June 25th

Fishing spiders

5:00 p.m. The first mile of road has turned into a green tube, and the garland of butterflies described on June 15th and June 22nd continues. The sky is clear and the air calm. Trees overhang above and views of the stream are obscured by thick underbrush except at picnic sites. The stream can also be accessed at small breaks made by anglers or at small natural breaks. There about ten of these breaks along the first road mile. I force myself through several of the breaks and look down to enjoy the cool, transparent stream. At each I find various types of spider webs: disordered tangle webs, sheet webs hung low just above the waterline, and the circular webs of Orb weaver spiders (Araneus sp.). Paradoxically, I see no spiders today, but their webs are full of hapless arthropod victims.

Lining the stream banks at these breaks are Bittersweet nightshade plants (Solanum dulcamara) a.k.a. Climbing nightshade with deep blue blossoms. These plants hug the stream’s steep banks and vertical rock retention walls, and they grow just above the waterline. At a few places along the first road mile, they incongruously protrude from the understory of serviceberry bushes (Amelanchier sp.), and there they are noticeable because their colorful blossoms are one of the few flowering plants that are left after the spring flower explosion. The Nightshade’s blossoms are either shriveling or extend vibrant yellow cones surrounded by blue petals. In the fall, these will yield bright red fruit.

Looking up from the stream and into the thick green sub-story, there are butterflies everywhere. They are the usual suspects for a canyon spring and early summer: Cabbage white butterflies, Western tiger swallowtails, Mourning cloaks (Nymphalis antiopa). These are now joined by White Admiral butterflies and by Common whitetail dragonflies patrolling overhead. I am used to seeing this floating butterfly assemblage traveling linearly on their feeding searches along bushes on the road’s sides, but here they fly in their natural setting. The butterflies follow large spiral flight paths broken by and traveling through the dense shrubs. In this setting, their frenetic sharp turns and chaotic shifts are necessary to navigate this complicated scene, and this explains these seemingly purposeless motions on their flights over the road. In this manner, the butterflies explore every possible hiding place in which a flowing blossom might be found.

At each of my stops along the stream, I see about five butterflies, and together with butterflies along the road, I estimate that there about 100 butterflies in the first mile road. Two Painted Lady butterflies (Venessa cardui) are also patrolling the roadside bushes. What flowering plant these butterflies are searching in the shurb understory is a mystery. The daytime flowering blossoms of spring are past, and only a few Foxglove beardtongue flowers remain open producing nectar. The only substantial flowering plant left is Yellow sweet clover. But the stands of this weed that line only the roadsides are fading, and on any one plant only one-third of the blossoms found at their peak are viable.

The fierce post-solistice sun begins to affect tree leaves. One or two Gambel’s oaks and Norway maples have a brace of leaves that are browned and shriveled at the edges. Once damaged, their leafs curl up, and the crabapple tree at the upper end of Pleasant Valley near mile 1.7 shows similar signs of stress. But the deciduous trees’ principal defense against the loss of water from heat and sunlight is a waxy layer on the upper surfaces of trees. This is best seen on the leafs of the western River birch trees. At the right angle to the Sun, their canopy flashes dappled green light for leafs titled away from the light and a blinding silver-white light for those at appropriate angle of reflection. University of Sussex ecologist Hartley notes that the waxy layer provides another benefit: it is some tree’s defense against caterpillars (Hartely 2009). Although caterpillars have evolved specialized feet to grasp leaf surfaces, caterpillars have a hard time walking over the wax layer, they fall off, and the plant is preserved. This may explain the caterpillars sometimes found along the road in the last week. I had supposed the caterpillars had crawled onto the roadway, but perhaps they have slipped and fallen from above.

Returning down canyon from milepost 1.5, insects are backlit by the Sun, and this makes them easier to see. At mile 1.1 near the entrance to lower Pleasant Valley, 30 to 40 Common whitetail dragonflies are circling between 50 and 100 feet above ground. Between the road surface and fifty feet, there are none. In cool places beneath the shade of trees, the prey of the dragonflies, groups of up to 100 gnats float. A small, immature desert tarantula (Aphonopelma chalcodes) scurries into the bushes.

Also mile 1.1, I hear raptor screams, and this repeats my earlier experience of June 21st. They are the unmistakable calls of two Peregrine falcons (Falco peregrinus). This time I travel back up canyon to get a better view, and below the eastern canyon wall near mile 0.8, more than a quarter-mile away, two peregrines are driving a smaller bird away from the canyon sides. There loud screams travel coherently through the calm summer air. This may be where the peregrines are nesting this season, but that side of the canyon does not have the steep cliffs found on its western walls. I note to watch this area closer to see if a nest can be confirmed.

Per Thoreau’s “Journal” on June 25th, 1852, he sees a rainbow in the eastern morning sky. He opines that younger birds are duller in color in order to protect them from predators. He hears a bobolink and a golden robin. He sees wild rose and butter-and-eggs. He notes that in cool air, the ridges on distant mountains are more distinctly seen. He describes a moon-light walk. On June 25th, 1853, he finds two bushes of ripe service berries and associated cherry birds. On June 25th, 1854, he sees a bittern. On June 25th, 1858, he sees two or three young squirrels playing. He observes how objects including grass and water skimmers cast lenticular shadows on the bottom of a river. He again notes how the lighter undersides of leaves illuminate dark sprout forests.

On June 25th, 1946, City Water Commissioner D. A. Affleck closed all lands in lower City Creek and above 14th Avenue to entry in order to prevent the possibility of grass fires (Salt Lake Telegram). Campfires were prohibited in upper City Creek Canyon (id). On June 25th, 1913, City officials plan to inspect the headwaters of Salt Lake valley canyons for water purity as part of a plan to develop more water sources (Salt Lake Telegram). On June 25th, 1896, new silver and lead ore bodies were discovered in upper City Creek Canyon about one mile from the old Red Bird Mine on Black Mountain (Salt Lake Herald). Mining work continues at other mines in the Hot Springs mining district, which includes City Creek (id). On June 25th, 1892, an old, destitute woman who had been living in cave in City Creek Canyon was sent to the hospital (Salt Lake Times).

The Oak Forest Over Time

External Link to Image

Comparison of Ensign Peak Area, Gambel Oak Forest – 1912 and 2017. Upper frame: author taken June 2017. Lower frame: W. H. Shipler taken September 12, 1912, Utah Historical Society. The foreground of the upper frame is contains cheat grass.

11:30 a.m. I am standing at the corner of 11th Avenue and Bonneville Drive where the road turns north above the lower canyon that leads to Guardhouse Gate. The Gambel’s oak forest is visible on the distant hillsides around Ensign Peak. Across the almost forty years that I have lived near the canyon, I have had the subconscious impression that the Gambel oak chaparral forest is expanding on the southern half of the Salt Lake salient hillsides that overlook the city and on the slopes that face the canyon. I take a photograph of the Gambel’s oak forest around the Ensign Peak area and begin looking for historical comparison photographs. One exists in the University of Utah Marriott Library archives taken by Salt Lake photographer William H. Shipler in September 1912 near the intersect of 11th Avenue and Bonneville Drive on the east side of the lower canyon. This was before Memory Grove and the State Capitol were completed in 1927 or any homes existed above the present State Capitol Building. The Ensign Peak oak groves appear in the background. Comparing the two photographs separated by almost one-hundred and four years, the Gambel oak groves in the gully to the north or and that leads to the peak have significantly filled in. The same is true of the next gully to the north through which the Bonneville Shoreline Trail passes. (Shipler 1912). Here, the Gambel’s oak forest is locally expanding.

Rogers of Columbia University matched a photograph taken by the Karl Grove Gilbert in 1901 with one that Rogers took in 1977 in Section 2, Township 3 South, Range 1 East, Salt Lake Base Meridian near the present day Karl Grove Gilbert Geologic Park west of the mouth of Little Cottonwood Canyon (Rogers 1984, Plate 45). (In 1890, Gilbert, a geologist, authored a landmark report on ancient Lake Bonneville (Gilbert 1890) and later succeeded John Wesley Powell as the head of the United States Geological Survey.) The Gilbert-Rogers photographs were of the Wasatch Front Mountain Range slopes that face the city west of Big Cottonwood Twin Peaks and Deaf Smith Canyon. Rogers noticed increases in the size of Gambel oak groves and maples on those western slopes (Rogers, Plate 46). I do other comparisons using two Landsat infrared images of Salt Lake City separated by thirty years and taken on July 14th, 1985 and on July 1st, 2015. Over those thirty years, I do not detect any advance or retreat of the oak forest along the ten miles between City Creek Canyon, Red Butte Canyon and Wire Mountain.

The oak forests surrounding Salt Lake City and in City Creek Canyon are extending their range, but only on selected lower Gambel oak chaparral slopes facing the city. Generally, the oak forest is stable and is not expanding.

Per Thoreau’s “Journal” on June 24th, 1852, he observes clouds and describes the virtues of watching clouds. He smells fragrances blowing off a meadow, and notes that twin flower (Linnaea borealis) is past its peak bloom. On June 24th, 1853, he notes that birds use hair to line their nests. On June 24, 1856+, he notes that the surface of springs are covered with dust and insects. On June 24, 1857, he examines a screech owl nest. On June 24, 1860, he sees young bluebirds.

In 1949, Christensen examined the distribution of Gambel’s oak forests along the Wasatch Front, and he concluded that the oak forests had in some local instances proliferated since the arrival of the Euro-American colonists (id. at 64). He found increases in maples on the Oquirrh Mountains on the west side of Salt Lake valley. Generally, Christensen concluded that most of the increases occurred after 1900 (Rogers, 19). In 1984, Rogers at Columbia University re-examined the question in light of the then developing question of climate change. He compared 49 historical images with some 400 contemporary matching photographs. Based on images hillsides near Tooele and west of Lone Peak, Rogers concluded that both Big Tooth maples and Gambel’s oaks were expanding at selected locations (Rogers, p. 136 and Plates 43, 45, and 46).

Rogers speculated, while calling for further research, that the cause of the expansion of Big Tooth maples and Gambel’s oaks was increased precipitation (Rogers, 136-137). He felt that although difficult to show with certainty, that improved fire suppression by modern Utahans was not the cause of the increase. The rate of fires after 1900 had been constant despite a ten-fold increase in fire suppression funding (id. at 140). In theory, the cycle of fire followed by rapid cheat grass invasion should slowly erode the boundaries of the existing oak forest. Rogers’ offered the tentative explanation that extreme cold weather in the late nineteenth century may have overwhelmed the negative effects of overgrazing and fire, and colder weather allowed the oak forest and maples to expand (Rogers, 138-139).

Rogers’ 1984 hypothesis is consistent with later, recent tree ring studies in the Intermountain West that reconstructed a 576 year precipitation record for Rocky Mountains, including Utah (Bekker et al 2014, DeRose et al, Wang et al; see January 30th and February 9th). From the tree rings, Bekker et al found that persistent, severe droughts were far more prevalent in the distant past than in the 150 years of Euro-American presence in northern Utah. The local advances of Big Tooth maples and Gambel’s oaks may have been a long-term, delayed response to more frequent rain and snow. However, beginning in 1984, the year that Rogers published his results, the number of acres annually burning in Utah has an increasing upward trend (Utah Department of Agriculture and Food 2013 at 8).

Rogers’ fire-invasive grass theory, Bekker et al’s climate findings, and the increasing trend in the number of acres annual burned in Utah wildfires raise the question of whether the maples and oaks will retreat in the future. Utah will become drier in the future, and whether that trend is the result of regression to the mean of past temperatures or human induced global warming is irrelevant. Whatever the cause, if annual temperatures increase, the oaks and maples should retreat uphill. In City Creek Canyon, rising temperatures will cause the oak groves near the ridgeline to retreat and in the Wasatch lower montane habitat that hugs the canyon’s stream, the mixed oak forest will contract closer to the stream’s banks.

On June 24th, 1994, in a historical piece for the Salt Lake Tribune, Jack Goodman concluded that the “Lone Cedar” tree at 300 South 500 East was probably a pinyon pine.

Masters of the Wasatch Steeplechase

8:00 a.m. It is Saturday, and in the cool morning air, birds are active. Black-headed grosbeaks and Song sparrows are the most common. This morning is also the 39th running of the Wasatch Steeplechase (Adams 2017). The Wasatch Steeplechase is purist running event whose 17 mile path goes up the south part of the Salt Lake salient, over the limestone knife edge at the top of Little Black Mountain, down Smuggler’s Gap, and then out the City Creek Canyon Road. Over the course, about 3,000 feet in elevation is gained and lost. Unlike other Salt Lake City running events, there is no registration packet, no inflated air start and finish line blasting loud rock music, and no prize money. About 200 runners just show up at Memory Grove Park at 6:00 a.m. and start. Participants tend to be lean ectomorphs between the ages of 25 to 50 years old, and the best finish the race in about two hours and fifteen minutes. Last place finishes in about six hours. The purist ethic of the race is reflected in its liability waiver agreement:

“Whereas, participation in the annual Wahsatch Steeplechase is a privilege and sacred ritual in celebration of the Summer Solstice and, whereafter, the undersigned acknowledges the uniquely and hazardous nature of the race course, including raging streams at full flood, wicked sagebrush, poisonous snakes, and precipitous crags, and has inspected the course or in the alternative freely assumes the risk or failure to inspect the course” (Adams 2017).

I am a stocky American football player-like endomorph. Although I have solo-run the track (in reverse direction) about nine times in the last forty years, my best jogging time was somewhat more than six hours, but each time the route was both an inspirational and mystical experience. First, the route goes up seven miles along the City Creek Canyon Road to the end of the paved road through both the Gambel’s oak and maple forest. Then a near vertical trail leads 2,000 feet through an upper montane forest of Douglas firs and Lodgepole pine trees that is thick with Stellar jays. Then the route goes along a knife-edge ridgeline for one-half mile along the top of Little Black Mountain. Here, one must boulder back and forth along limestone ledges that tilt downhill and away from the direction of travel. In most places, a slip means a fall of ten to twenty feet onto a sixty degree slope. Survivable, but something to be avoided given the difficulty of extraction from this high mountain. Next is a about ten miles stretch under the watchful eyes of hawks and eagles that descends back through a Pinyon Juniper forest, along the Wild bunchgrass southern salient past the Little Twin Peaks, and then back through the Gambel’s oak forest to the canyon bottom. Along the summit and south salient, expansive views of the urbanized Wasatch Front cities, the Great Salt Lake, and the Bonneville flats extend at most one-hundred and fifty miles. In some years, dramatic summer storms flow across the Great Salt Lake dropping streamers of lightening from gray and black clouds. The route is a tour-de-force of the many of the Great Basin’s habitats. The Steeplechase is less of a run and more of a spiritual experience brought on by fatigue, dehydration, strong summer sunlight, and exertion at altitude. After each traverse of the route, I fall into a meditative, contented state for one, and if I am lucky, two days.

In September, another extreme race, the Wasatch 100, goes from 100 miles from Farmington, north of City Creek Canyon, along the upper headwaters of the canyon, and onto Park City, Utah, a mining town turned upper income ski-resort. The maximum allowed finishing time is 36 hours. Unlike the Steeplechase, the Wasatch 100, which is beyond my physical capabilities, has a more tradition competitive road-race feel, and by disposition, I have always favored the Steeplechase.

Per Thoreau’s “Journal” on June 17th, 1852, he notes that crickets sing loudly in the morning after hot summer nights. He sees or hears a brown thrasher, a red-eye, an oven-bird, and a wood thrush. Citus are blooming. He notes how a boulder has made a micro-habitat in which several tree seedlings have taken root. On June 17th, 1853, he notes that pogonias, adder’s tongue, blue-eyed grass, lambkill and mountain laurel are at their peak. He records an egg in a night-hawk nest has hatched. On the morning of June 17th, 1854, he feels dew covered grasses and sees cobwebs hanging across the grass.

On June 17th, 2000, the First Congregational Church planned to hold its annual outdoor service in City Creek Canyon. On June 17th, 1915, P. J. Moran was awarded the contract to build the reservoir at Pleasant Valley for the sum of $18,209.59 (Salt Lake Telegram). On June 17th, 1915, a locomotive was hauled to the capitol grounds along newly constructed track along the west side of City Creek (now East Capitol Street) to begin grading for the new state capitol building (Salt Lake Herald). On June 17th, 1894, the City changed from having a staff of full-time water tankmen (who clean water tank filters) to a part-time staff of day and night patrols (Salt Lake Herald).

Sego Lilies and Cheat Grass

6:30 p.m. The jet stream has reconnected over the Intermountain west to its usual spring route, and this has brought back strong, cooling breezes. This evening, I drive to the end of the road at North Terrace Hills Drive to walk up the trail from the Avenues to the south ridgeline of the Salt Lake salient that looks down into City Creek Canyon. I am looking for the Sego lily which blooms this time of year. One-quarter mile below where the trail intersects the road, I find patches of this Utah state flower (November 30th) among the parched Cheat grass. It is a bulb flower that rises from the hard ground sometimes without any leaves, and its four inch blossoms have delicate cream petals that are yellow at the base surrounded by splashes of dark red-purple. Against this central yellow backdrop, contrasting thick, white-colored stamens rise. I estimate about 80 lilies along are within a 100 feet along the trail for one-half mile below the ridgeline. Like most native desert wildflowers, it is a metaphor for beauty under adversity.

Also along the road are blossoming Canadian thistles (Cirsium arvense). Although a weed, its three inch light purple blossoms are a visually pleasing example of complexity in nature. Hundreds of small, spike like petals surround a central circular whirl of about 150 short, cylindrical, vertical stamens. The whirl pattern in its stamens betrays two counter-spirals of stamens that are arranged in left and right spiraling Fibonacci series.

Near the Sego lilies, there is a 10-inch diameter coyote burrow in the road bank to the west of the trail. That it sits along a heavily traveled mountain biking trail – perhaps between 50 to 100 people traverse this route each day – is unusual. It is not clear whether the burrow is currently occupied. The mouth of the burrow shows no recent signs of entry or exit, but there is contrasting excavated soil radiating below the entrance.

Below the ridgeline back over a mile to the trailhead, Gambel’s oak forest covers most of the land to the west of the trail, but the oaks only cover patches of ground to the east. Birds sing from their hiding places. I see Black-billed magpies at the trailhead and a Green-tailed towhee within the first quarter-mile. Near the ridge, Song sparrows, Black-headed grosbeaks, a hummingbird, and chukars are heard. From their calls within one-third of a mile of the ridgeline, I estimate 150 birds are present. None appear to be flying.

I reach the east-west running ridgeline and begin to climb another 150 feet to a small peak to the east of the intersection of trail and ridge. As with my last visit to this peak (January 5th), wind is blowing strongly from the north. The reason for the song bird’s grounding becomes apparent: in the steady wind, an avian farmer, a Cooper’s Hawk, hovers motionless about 20 feet above the ridge. The low Sun is filtered through clouds to the north, and its light sets the yellow molted breast feathers blazing. The hawk continues for hover for another minute, turns and glides off to the east just below the ridgeline.

From the peak, which bears a concrete and metal Salt Lake City survey corner marker indicating an altitude of 4,905 feet, or about 900 feet above the valley floor, there is a clear view down 20 miles of Wasatch Front Mountain Range from Grandview Peak and Little Black Mountain on the north, to Lone Peak on the south. In the evening light, the two sandstone geologic “U”‘s synclines that define Red Butte Canyon, Emigration Canyon, and part of Parleys Canyon are easily seen (January 9th). These sit on top of a larger deeper “U” shaped syncline of limestone that stretches from City Creek Canyon on the north and emerges again in Millcreek Canyon on the south. Perhaps this geology also explains why the streams in Red Butte and Emigration canyons reduce to trickle. Unlike City Creek and Millcreek with their limestone upper canyons, the surface bedrock of Red Butte and Emigration are porous sandstone. (Parleys Canyon contains two dams that hold back the stream.) Underground water may not be trapped along limestone layers. This is speculation, and another possibility is that Red Butte and Emigration canyons, unlike City Creek, were never reforested after the foresting and mining eras of the last half of the 19th century. Summer surface water may simply evaporate. To the west, the jet stream is marked by a fast moving line of clouds that extends from the southwest to the northeast.

Looking at the lands around the peak, they are one-third green oak forest, one-third dried brown Cheat grass, and one-third still green native brome. It must have been an impressive spring sight of green meadows before the invasive grasses arrived. The peak itself is covered in Cheat grass about six inches deep, and because of this year’s heavy winter snow, an acquaintance reports stands several feet in height along the Bonneville Shoreline Trail below this peak. The cheat grass is read to burn, and within the last week across the state, six large cheat grass wild fires of over 1,000 acres have burned. Several smaller cheat grass fires of a few acres in size also occurred in Salt Lake Valley over the last week, but those were quickly suppressed. Although overgrazing immediately after the Euro-american colonization of the valley in 1847 quickly converted fire resistant native bromes and bunch grasses to non-native adventive grasses spotted with sagebrush (March 13th), cheat grass was not present in the valley or on the Avenues ridgeline. This weed grass was introduced in California in 1870 (id), and the grass followed along the railroads lines east (Monson and Kitchen, 1992, p. 24), but may have also traveled as a contaminant in feed grain (id at 33). Cheat grass was first collected in Utah in 1894 by M. E. Jones on Provo, Utah (Barbour and Billings, p. 264; Monson and Kitchen). How fast it overtook native grasses statewide is unclear, but in 1932, Pickford of the Intermountain Forest and Range Experiment Station noted that while Cheat grass, which he called Downy brome, was found in all areas of the north half of the state, it was only dominate in the Great Salt Lake area (Pickford, 1932; Monson and Kitchen, 24). Pickford found that Cheat grass was most dense (11 percent coverage) on plots that had been both grazed and then subjected to a grass fire, but it was absent from plots that had never been grazed or subjected to a burn. What makes Cheat grass different is the higher frequency of its burn cycle and the higher temperatures at which it burns (Monson and Kitchen, 24). There is a direct relationship between the level of the prior winter’s precipitation and cheat grass fires in the following summer (Monson and Kitchen, 24). One-hundred and twenty-three years later, this hot burning grass covers the Avenues ridgeline, more than half of the City Creek canyon walls of the Salt Lake salient, and much of the State. The state and federal agencies spend about 83 million USD per year fighting wildfires in Utah (Stambro et al, 2014, Chap. 9), and much of that total is related to cheat grass fires.

The peak is also covered in unidentified, one-half inch nymph crickets. When walking forward, every step raises five or six nymphs that jump forward to avoid being crushed. They are marvels of camouflage, and their dark brown, light brown, dusky yellow and dirty white colors perfectly match the surrounding dried grass. They move at the slightest provocation and it takes several attempts to locate one for a photograph. Even knowing where it is, I have to stare at the brown grass for fifteen seconds before I can make out the cricket’s outline.

Despite the invasives, the expansive view of the surrounding hills and mountains is inspiring, and I return home a happy and contented person.

In Thoreau’s “Journal” on June 10th, 1853, he notes honey locust, black willows and blackberries are in bloom. He hears a robin. On June 10th, 1856, he watches a huckleberry bird and finds a pigeon woodpecker nest with young. On June 10, 1857, he sees a snake. On June 10, 1860, he examines a bat suspended in the daytime forest.

The Fibonacci series seen in the whirls of the center of a bull thistle plant reappears in many plant contexts, including how seeds are distributed around a pine cone (Klar, 2002) and how branches are radially distributed around on tree (Nelson 2004). The study of the arrangement of leaves on a plant is called phyllotaxis. There are several competing hypotheses for how leaves self-assemble themselves themselves in a Fibonacci series, and the prevailing theory is that these spatial patterns are the result of most-efficient packing solutions (Klar). Hormonal diffusion is also theorized but the actual mechanisms are unknown (id). Limited progress has been made in defining the theoretical mathematics of how a circle of undiffentiated meristem plant stem-cell tissue can transform into a spiral pattern and on identifying candidate biochemicals that control the process (Flemming, 2002).

Restoring areas contaminated with cheat grass has proven difficult and expensive in terms of both capital and labor (Barbour and Billings, p. 264; Monson and Kitchen). Salt Lake City and Salt Lake County have spent over 150,000 USD since 2008 trying to rehabilitate about 180 acres (0.3 square miles) in City Creek and Parleys Canyons that are contaminated with both Yellow starthistle and Cheat grass (see May 21st). The best strategy for restoration is reseeding following a cheat grass fire, but its effectiveness is limited to level areas (Barbour and Billings, 264-265) and not the steep slopes of City Creek Canyon and the Salt Lake salient. Although the city considered a controlled burn program in City Creek in 2010 (Gray and Harrison, 1999; Salt Lake Dept. of Public Utilities 2010, Salt Lake City Corporation 2010a), it was not pursued, and currently the Utah Conservation Corps is using the labor intensive method of manually denuding and spraying fields in lower Pleasant Valley, including along a steep slope (May 17th and May 21st).

On June 10th, 2006, students at the Design Workshop recommend daylighting City Creek Canyon stream from the mouth of City Creek, along North Temple, all the way to the Jordan River (Salt Lake Tribune). Daylighting means raising the creek which now traverses the city’s center in underground pipes back to the surface. (Prior U.S. Corps of Engineer and City proposals recommended daylighting City Creek beginning at 700 West.) On June 10th, 1898, the National Guard plan exercises in City Creek Canyon (Deseret Evening News).

First Loud Cricket with Metamorphosis

7:00 p.m. True night does not come until after 9 in the evening, and the start of the estival season is one week away. It the sixth day of late spring heat in the nineties, the jet stream is forcing its way into the Intermountain west, and the jet stream traveling southwest to the northwest over adjacent Nevada. This has brought high winds to the canyon. The leaved trees whip back and forth under its hand. In response to the days of heat, invasive Cheat grass (Bromus tectorum) that covers the hillsides on both sides of the Salt Lake salient have dried to an early season brown. The hills are a patchwork of brown Cheat grass and other later maturing bromes that are still green. Cheat grass is susceptible to burn in quick moving, high temperature fires, and authorities are worried over a bad fire season. Utah normally has 400 grass fires per year. Under the force of the wind, small birds restrict themselves to short thirty foot flights between trees. At the pond at picnic site 5, I startle a grounded Song sparrow, while a Black-headed grosbeak performs its trill call overhead.

As the wind starts to die down, I hear the first loud cricket – just one – of the season. I suspect that these also may be the cicadas heard yesterday in the tops of Gambel’s oaks (June 7th), and their wings have hardened overnight. In two months, large choruses of crickets will fill the canyon night air (August 15th and August 18th). Large mosquitoes (sp. Culiseta), possibly Marsh mosquitoes (Culiseta inornata), fly through the shadowed evening light.

In Thoreau’s “Journal” on June 8th, 1851, he notes white pines have stamen blossoms. On June 8th 1853, a pair of hawks swoop on him as he walks near his nest. He notes that white pine is in flower. On June 8th, 1860, he notes that the summer afternoon shower season has begun. Red oak leaves have fully developed.

* * * *

Whether cricket or cicada, this clicking insect is a newly hatched pupae that has likely undergone some form of metamorphosis. In complete metamorphosis (holometabolous), such as that which occurs in butterflies, the egg hatches a larvae caterpillar, the caterpillar weaves a pupal sack, and then an adult emerges. In incomplete metamorphosis(hemimetabolism), an insect egg develops into an miniature adult, the nymph, and as it expands, it sheds its exoskeleton as it grows. In the canyon, incomplete metamorphosis is seen in crickets and Box elder bugs. Among the vertebrates, frogs and salamanders also undergo metamorphosis. Since insects, numerically, are the most diverse type of animals, 45 to 60 percent of all animals on the Earth undergo metamorphosis, and our mammalian form of infant development is a relatively infrequent mode (Jabr 2012). The evolutionary just-so story by which metamorphosis arose is that an intermediary stage of development allows the larval and nymph stages to exploit different food niches from adults in the same habitat. Truman and Riddiford suggest that natural selection acted on the hormonal mechanisms of ancestral species to create the radically different developmental stages (Truman and Riddiford 1999).

On June 8th, 2003, the Salt Lake Tribune reported the experiences of many Salt Lake Valley residents in how they use the local canyons, including City Creek Canyon. The Outdoor Industry Foundation is conducting a study of dispersed recreation use in Utah, and it finds that 81 percent of Utahans engage in outdoor activities (id). On June 8th, 1951, The Audubon Society scheduled a trip up City Creek Canyon (Salt Lake Telegram). On June 8th, 1950, City tests of City Creek Canyon water show a high degree of purity and low coliform count (Salt Lake Telegram). On June 8th, 1933, the Wasatch Mountain Club scheduled a hike from Rotary Park in City Creek to Mueller Park (Salt Lake Telegram). On June 8, 1906, a committee of the City Council recommended that a permit to allow Henry B. Anderson to harvest 24 cords of cedar wood in City Creek be denied on the grounds of a need to protect the watershed (Salt Lake Telegram). On June 8, 1895, the Utah Forestry Association reported on its activities in reforesting stands of trees in City Creek Canyon (Salt Lake Herald). The Association also resolved to compile data on the extent of deforestation, rainfall and its impact on flooding (id).

June 2nd

Evolution of Angiosperms

8:00 a.m. Some days are beyond beauty. This is the first official day of the five months in which cars are allowed in the canyon on alternating days, and I have decided to drive up to the end of the road to jog the uppermost canyon. It rained last night, the undergrowth and trees are all covered with thick layer of drops. As I drive up the road, the morning birds are active. With the windows open, I mentally tabulate a count as I slowly travel up the winding road. It comes to about 20 birds within earshot for every quarter mile. This suggests a population of some 800 smaller song birds along the five and three-quarters of paved road and the subsequent 2 miles of trail in a band for 50 yards on either side of the road.

Continuing the drive up canyon, Wild roses are open to Pleasant Valley, mile 1.1, and Wild geraniums are open to mile 5.0. Along the first mile, a new flowering plant, another weed, has sprung up to two feet tall seemingly overnight. It is Western salisfy (Asteraceae tragopogon dupon). Although a noxious invader, it is an admirable plant. To avoid the heat of the day, it folds closed into a pen-like tip, but now in the light morning sun, it shows sixteen thin yellow petals surrounded by hair-thin sepals. The center has a sharply contrasting black band. It lines the roadside and at Pleasant Valley, Utah Conservation Corps treated field, that removed yellow starthistle, is now covered with another invasive – salsify. A purple variant of this plant is also found along the first mile road.

At the water treatment plant at mile 3.4, the canyon narrows, and flashes of blue and black flittering into the Gambel’s oaks reveals a flock of Stellar’s jays. Stellar’s jays prefer the coolness of a montane habitat, and in contrast, their cousins, the Scrub jay, prefers the hotter lower canyon. But the Stellar’s jay is more territorial, and thus, more entertaining. When a hiker enters their territory, one will immediately swoop down to the trail and call with its repetitive “caw” in both curiosity and in complaint. The action of one will others of its tribe, and this provides the walker with an avian presidio under which one must pass inspection. Later in the afternoon, further up the trail at the end of the road, as I walk under a large moss covered log, a Stellar’s jay lands above me, its mouth full of moss intended for use as nesting material. It glances back for a quick inquisitive look and then proceeds on its business.

Resuming the drive up the road and as the walls of the canyon close in, the canyon transitions from Gambel oak forest to deciduous maple and Box elder tree forest. The road becomes a single track. The heavy moisture on the leaves is heated by the first penetrating morning sun, and as a result, the air is thick with mist and dew. Shafts of light peak make it through the dense overgrowth and illuminate the mist into yellow tubes. Here, the canyon feels most like an eastern forest. Although the dense greenery only extends for a few hundred yards on either side of the road, the narrow canyon walls cut off any vistas, and this is what I remember of my boyhood eastern forests. The green goes on forever and the all sense of direction is lost. Here, stream bed widens and the stream slows. But then, near mile 4.5, there is an abrupt transition to a Rocky Mountain forest (Peet 2000) dominated by Douglas fir and Norway spruce. The stream narrows and the stream bed becomes boulders that are angular and freshly honed from bedrock. This change is also announced by great vertically upended limestone fins on the western wall of the canyon that have been turned by earthquake faults (Sept 1st). The Wild geraniums thin out, and the first Mountain bluebells, a cool weather plant, appear and become more frequent. The air thickens more and forest becomes medieval.

Along this stretch of road between Lower and Upper Rotary Park, the bird communities, mostly of American robins, Song sparrows, Warbling vireos, and Black-headed grosbeaks are spread out into distinct communities, unlike in the warmer first mile canyon. The distinct trill call of a community of Chirping sparrows is heard. I also hear a lone Mountain chickadee calling. This is where they have come, since the lower canyon is too hot for them. This segregation of birds into unique groups along the road gives me the opportunity to stop and study the distinct songs and calls of a group of Warbling vireos.

The sun rises further and the mist burns off as I reach the end of the road at mile 5.75, and the old mining road and trail that leads to the Treasure Box mine begins. I have not been here since the end of last summer (Sept. 8th), and it feels restorative to be in the most natural of the canyon’s regions. Leaving the car and proceeding up the trail, where the direct sun penetrates, a green canopy of maples and box elders closes in, while on shaded eastern slope, Douglas firs reach to trails edge. The air is heavy with the smell of wet leaves and chlorophyll. Crossing the first and second red metal bridges affords views up the stream, and it is a torrent of white, with only hints of blue water. The stream has become a silver ribbon. After the third metal bridge, the trail rises, the canopy deepens and the undergrowth becomes impenetrable. This stretch is as the lower canyon appeared around 1900. Shipler’s photograph of the lower canyon road taken around 1903, appears nearly identical to this morning’s rise in the trail (J. Willard Marriott, Id. 459448, see also Salt Lake Tribune, May 24, 1903). The chirping call of a Green-tailed towhee is heard.

For the next half-mile, the trail is about 150 feet east of stream, and the trail consists of sharp rocks that a month ago were another snow-feed branch of the stream. Geraniums and blue bells thicken along with young stinging nettle plants. All are so covered with last night’s rain water that my shoes quickly become soaked, but I do not care. A Mourning cloak butterfly with an odd color variant flies down canyon. Instead of the yellow-white trailing band, its trailing wing band is a dusky orange. Other now common butterflies appear uniformly distributed along the trail: Western tiger swallowtails and newly-hatched smaller Spring azure butterfly butterflies. The Spring azures flock in groups of three to six, and the harsh high-altitude light brings out a new property to their colors. Depending on the sun angle, their wings flash a deep medium blue, their streaked light blue, or flat light blue. The deep blue is new variation to their iridescence. There is a new unidentified one and one-half inch butterfly. It has forewings of patterned medium dark grey and rear-wings that are a grayish black. The colder air at this high altitude, along with their lack of exposure to humans, make insects sluggish. In the lower canyon, the Red-rumped central worker bumble bees are skittish. But here, the bees remain still when approached, and I am able to take a clear pictures of several.

Song sparrows, Warbling vireos, a Spotted towhee, Yellow warblers, and Lazuli buntings, another refugee from the lower canyons, are heard in profusion. But again, they rest in distinct communities in the spacious upper reaches of the canyon instead of being distributed uniformly along the trail. Jogging uphill feels good for the legs, but my progress is slow. I cannot resist the urge to stop and listen to each community of bird and to playback stock recordings of their calls, in part to assure to identification, and in part for the simple enjoyment of somehow communicating with them. At one point, the land between trail and stream widens, but is particularly lush with a low canopy. There I hear a single American dipper, the first of the season.

For the next half mile, the trail begins to narrow travels next to the stream, and the trail crosses a series of rock outcrops. There the trail becomes broken rock interspersed with patches of stream feed marsh, and the stream water itself is so pure that individual rocks can be seen distinctly on the stream’s bottom. A few Spearleaf scorpionweeds (Phacelia hastata) that have delicate light purple, fuzzy blossoms, hide in sun sheltered spaces. Along the broken rocks, I notice the small, 5 millimeter, dried-out shells of snails covering the trail. Over a 100 feet of trail, I count about the same number of shells. On picking one up and to my astonishment, there is a miniature live snail in each shell. I am unable to identify them.

Next, the trail starts to rise towards the first of four hanging meadows, and in the first of which stills with Louis Meadows SNOTEL weather station. Aspen trees first appear, a sure sign of a Rocky Mountain meadow ahead. Mountain bluebells surround the trail on both sides, and a few Western blue elderberry trees (Sambucus nigra ssp. cerulea) rise from the surrounding bluebells. Each elderberry is heavily festooned with white, lacey panicles. In the autumn, as their dark fruit ripens, these are a favored trail snack.

As I crest the lip of Louis Meadows hanging valley, the SNOTEL station comes into view. It sits in the middle of field of Mountain bluebells the size of two football fields, and the field is surrounded by a grove of waving aspen trees to the west and Douglas firs to the east. It is an idyllic sight; one that I feel privileged to experience. I begin to feel giddy and overwhelmed by biophilia.

While my heart feels love, my intellect says my expansive feelings are not the effect of altitude at just 6,700 feet (2,042 meters), but of ultra-violet radiation. The 10 a.m. summer Sun is high in the sky, and its warmth penetrates all clothing. The exercise of hiking in Western summer mountains is a relaxing experience. The cool air makes hard, fast hiking enjoyable, but at the same time ultra-violet relaxes the muscles and the mind. Pictures taken here today all are blue tinged from the uv light. With every 1000 meters in altitude, uv light increases in intensity by 10 percent. An internet uv intensity calculator suggests this morning’s ultra-violet index is 12.

As I nearly reach the trailhead and the car, the only other hiker in the canyon today, a young man in his twenties, overtakes me, and he can only mutter, “That is so unbelievably beautiful!” as he passes by. Words escape us both. We have been closer to creation and the other world of the upper canyons of the Wasatch Mountain Range.

Driving out the lower canyon and back to that other reality of my human social and economic existence, the Mosquito Abatement District surveyors are examining their blue painted tree holes (November 7th). They are taking a census in order to estimate the canyon’s mosquito population.

In Thoreau’s “Journal” on June 2nd, 1853, he travels through a thick fog and notes that birds are still making song. He sees cherry birds and yellow bluebead lily, an eastern plant, and red sorrel. On June 2nd, 1855, he describes a moth cocoon opening. On June 2nd, 1858, on a camping trip to a mountain top, he examines a snow bird nest, and hears a chewink, a wood-thrush, and night-hawks. On June 2nd, 1859, he finds a grossbeak nest in a blueberry bush. On June 2nd, 1860, he sees bats and a king-bird.

Fully preserved angiosperms first appear in the fossil record about 130 million years ago and by 90 million years ago, flowering trees had dominated the forest canopy. Pamela and Douglas Soltis at the University of Washington with Mark Chase at the Royal Botanical Gardens used modern gene mapping to reconstruct the evolutionary phylogenetic clades of flowering plants (Soltis, Soltis and Chase 1999). Soltis and Soltis review state-of-the-art flowering plant clades as of 2004 (Soltis and Soltis 2004).

Magallon and Sanderson at the University of California at Davis used the rate of diversification of woody plants in the fossil record to estimate the age of the major families (Magallon and Sanderson 2001, Fig. 4). Members of the Sapindales family, which includes maples seen in the canyon, appeared about 60 million years ago. The Rosaceae family members in the canyon, which include Western serviceberry, apple trees, chokeberry, ash trees, and Woods rose, evolved relatively recently, about 45 million years ago (id). Modern oaks appear about 35 million years ago. In Utah around 35 million years ago, the Farallon Plate had passed through Utah, crustal spreading behind the plate cracked Utah’s surface, and the spreading generated Utah’s volcanic era (January 7th). The volcanic breccia at milepost 1.0 of the canyon was forming (id).

On June 2nd, 2002, teenager Elizabeth Smart was kidnapped from her Federal Heights home and was hidden on the south slope city side slope of the Black Mountain-City Creek ridge for two months (Salt Lake Tribune, March 15, 2003). The hiding place was not found by a 2,000 person search organized by the Laura Recovery Center (id). On June 2nd, 1915, the City Commission approved plans to build a 5,000,000 gallon reservoir at Pleasant Valley (Salt Lake Herald). On Decoration Day (May 30), a picnic was held in City Creek as reported on the social page of the Deseret Evening News.

May 29th

Memorial Day

3:00 p.m. Today, I drive up to mile 4.2, picnic site 20, and jog in the upper canyon to mile 5.1, and the Weeping Rock Cave. While the lower canyon and city are in the summer-like eighties, the upper canyon remains in the low sixties. In the lower canyon, all Gambel’s oaks have leafed out, but at milepost 2.0, most are not leafing. There is distinct band of bare oaks or oaks that have leafed out by twenty to thirty percent, but the canyon’s appearance is still a heavily wooded green, because all of the other deciduous maples, ash, and cottonwood have leafed out. These create an illusion of green around the stream, but the maples, together with Douglas fir and Norway spruce, block the view of the oaks further away from the road. The higher one goes in the canyon, the less leaves that oaks have until a glimpse of slope at milepost 4.5 and Lower Rotary Park shows all the oaks to be leafless. The upper canyon transitions from oak woodland to a mountain fir habit, and by mile 5.0, over half the trees are firs or spruces.

Although the stream is at first wider than the lower canyon, near mile 5.0, the canyon narrows as vertical limestone fins, turned by earthquake faults (Sept 1st). The canyon closes in further and the stream turns into a white, turbulent mass as it crosses younger volcanic rocks. This western canyon feels more like an eastern forest because it is directionless. Green meets the eye in all directions, and only the flowing of the stream gives a sense of location or direction. American wild mint (Mentha canadensis) grows by the roadside, and I gather a few leaves to make tea with at home.

The butterflies have taken refugee here, having followed the thermocline up canyon. Fifteen Desert elfin and Spring azure fly intertwined a dance. Mourning cloaks abound. Blue-eyed barner dragonflies are seen. Unlike the hotter lower canyon, the shaded upper canyon with its step sides is flooded with insect life. Numerous small biting flies and other insects force me to move on after stopping for a few minutes. Picnickers light fires to keep the insects at bay. There is enough life here to keep small birds well fed.

Bird communities along the road are dispersed, homogeneous and larger than in the lower canyon. Warbling vireos dominate near mile 5.1. Song sparrows are at mile 4.8. The large group of vireos allows me to spend sometime listening to their calls with some assurance of matching unusual calls to a species. A bird will make familiar textbook Warbling vireo call, followed by another unrecognized call. I hear three distinct vireo calls that I cannot match with catalogue recordings for this bird. A single female Broad-tailed hummingbird (Selasphorus platycercus) hovers a few inches off the ground inspecting a dandelion. A few flashes of blue streaking into the forest reveals Stellar’s jays. A Rock squirrel peaks from around a bush. Returning down canyon, a mallard pair floats in the flood retention ponds below mile 3.0, but I see no chicks.

At Weeping Cave, the stream is split in two. The western stream carries about 12 cubic feet per second of water down-canyon in a torrent. The eastern branch consists of about 2 cubic feet per second of subterranean flow that emanates from a vertical Mississippian limestone fin. The fin itself is distorted into melted lines of red and browns, not from water, but from extreme heat when this outcrop was buried far underground. On one volcanic boulder in the stream’s middle, a Red maple and a Norway spruce shrub are growing from crevasse in the bare rock. Backlit by the southwest sun, the maple casts a reflection of a pure light green on the flat water’s surface.

Returning down canyon, a mallard pair floats in the flood retention ponds below mile 3.0. I see no chicks. The heat, the sunlight, and that it is a holiday, make everyone in the city lethargic. No one is focused, including myself, and a day of relaxation is the rule.

All parts of City Creek Canyon function as a place of remembrance and grieving. We connect death with a return to nature, and it is not uncommon to read about, hear of, or pass small informal wakes in the canyon. Memorials are also left by people grieving the loss of loved ones along City Creek Canyon road. Physical memorials typically consist of cards or a handwritten note with flowers left at the base of a tree. A specific part of the canyon, Memory Grove, has been set aside for grieving and formal remembrance of war dead.

The origins of Memory Grove begin in 1912 as a general use park, similar to Liberty Park. On April 14th, 1912, a petition from citizens proposed the creation of a park system for the city, including establishing a park at the canyon’s mouth, now Memory Grove (Salt Lake Tribune). Memory Grove was created in the context of the construction of the State Capitol Building and the aftermath of World War I during the 1920s. In 1920, the Gold Star Mothers of the Service Star Legion asked the city to donate land at the mouth of City Creek Canyon to create a memorial park for their sons who died in WWI (Salt Lake Tribune and Goodman, May 30, 1993). On April 25th, 1920, the Salt Lake Herald published an artist’s rendering of a proposed iron bridge that would cross City Creek at 7th Avenue. A similar proposal was suggested by G. A. Iverson of Northeast Bench Improvement Association on May 24th, 1920 (Salt Lake Telegram). The bridge was to be part of a proposed memorial WWI war dead at what is now Memory Grove. By the end of 1920, the Gold Star Mothers had purchased 300 trees and planted them near the mouth of the canyon (Salt Lake City Tribune and Goodman, July 31st, 1994). On November 5th, 1920, a subcommittee of the City Planning Committee, including Mayor Clarence Neslen, outlined plans to create a new park at the canyon’s mouth (later Memory Grove) and to turn City Creek Canyon into a large park (Salt Lake Telegram). By 1926, Mrs. E. O. Howard, a Gold Star Mother, raised 60,000 USD from private donations, a state appropriation and contributions from the city and county for the park and Memorial House construction (Salt Lake Tribune and C. Monson, Sept. 16, 1994; Salt Lake Tribune and Goodman July 31st, 1994), or about the equivalent of 830,000 USD in 2017. The Memorial House was to be constructed by renovating the abandoned Salt Lake City Waterworks maintenance shed. On December 17, 1926, the Salt Lake Telegram reported that a mature horse chestnut tree, that was being dug up at the corner of 100 South and 300 East, was being donated and relocated to Memory Grove Park in City Creek Canyon. On May 30th, 1927, Governor George Dern (grandfather to actor Bruce Dern and great-grandfather to actress Laura Dern) dedicated a monument to the Mormon Battalion at the southeast corner of the Utah State Capitol grounds that overlooks lower City Creek Canyon and Memory Grove (Monument plaque visited May 2017). The sculpture was rendered by Chicago artist Gilbert Riswold (id).

Memory Grove Park was constructed in increments from 1920 through 1927, and Memorial House served as the meeting place and wedding chapel for the Gold Star Mothers for several decades thereafter (Salt Lake Tribune, July 31, 1993). In 1920 and 1924, trees were planted (Salt Lake Herald, April 16, 1920; Salt Lake Telegram, April 15, 1924). On June 14, 1926, the Memorial House was dedicated (Salt Lake Telegram). On June 27th, 1926, a tablet containing the names of 732 Utahans killed in WWI was unveiled (Salt Lake Telegram, June 24th, 1926). In a March 1927 ceremony, Gold Star Mothers R. W. Fisher and Clesson Kinney noted the contributions of “Mayor Nelsen, Councilman Crabb, Mr. Slater of Liberty Park, Mr. Parkinson of the U.S. Forest Service” to the park’s creation (Salt Lake Tribune, July 31st, 1994). On October 8, 1927, the Austin Artillery Memorial was dedicated (Salt Lake Telegram). The Austin Artillery Memorial, an obelisk to the north of the pink meditation chapel, commemorates Capt. James Austin and three other Utah officers who were killed in the Argonne Forest during WWI (Salt Lake City Tribune and Dawn House, May 26, 2003). During this period, the Rotary Club constructed the related Rotary Club park at miles 4.5 and 5.5 of City Creek Canyon (Salt Lake Telegram, August 17, 1927).

Riswold sculpted the art deco female reliefs on the columns at the entrance to the Grove. They set the grove’s tone. In a west relief, a Grecian clothed mother looks over her shoulder to a military cross in the background. Riswold also did the sphinxes on the entrance to the Masonic Temple near 700 East South Temple (Utah Capitol Preservation Board 2017). In 1932, a second round greek style structure was added to the south of meditation chapel. It holds an octagonal bronze plaque that lists about 732 Utahans killed in WWI (Plaque visited 2017).

On April 2nd, 1935, Gold Star Mother E. O. Howard of the Salt Lake Gold Star Mothers Committee presented the Committee’s opposition to a City Street Department Plan to build a bridge across City Creek Canyon above Memory Grove (Salt Lake Telegram). They supported a plan to build stone stairs on the east side of Memory Grove to the Avenues.

World War II saw the addition of other monuments. On July 28th, 1948, the war dead chapel was dedicated at Memory Grove in front of a crowd of 10,000 (Salt Lake Tribune and John Ure, November 9th, 1997). This is the pink granite chapel in the center of the park. The Memorial Chapel was donated by the family of Ross Beason Jr., a pilot killed off the coast of Italy in WWII, but whose body was not found (House 2003). The Beason family dedicated the Memorial Chapel to all soliders whose bodies were never found (id). A step leading to the Chapel reads “In memory of 42 brave sailors who followed me to their death. C.A. ‘Red’ Beam, USN (ret.).” Beam dedicated the step in memory of his platoon that was wiped out, except for himself, during a WWI raid on Tarawa Island (House 2003). This step could not be found in 2017. 1,405 Utahans died or were missing in action in WWII (United States Military Archives 2017).

In May 1983, the park was damaged during a 100 year flood of City Creek. On February 3, 1991, the City Parks Department considered proposals to renovate the then abandoned Memorial House in Memory Grove (Salt Lake Tribune). On October 4th, 1994, the Utah Heritage Foundation reopened the renovated Memorial House, where its offices remains today (Salt Lake Tribune, October 16th, 1994). On November 9th, 1997, the Memory Grove Foundation announced its plans to raise $500,000 to renovate war memorials in Memory Grove (Salt Lake Tribune). On May 9th, 1999, the successful completion of the Memory Grove Foundation’s program to repair monuments in City Creek Canyon was reported (Salt Lake Tribune). On August 11, 1999, trees in the park were substantially destroyed by a tornado (Salt Lake Tribune, August 18, 1999).

On September 24th, 1999, Rep. Ralph Becker announced a $250,000 grant from the Metropolitan Water Conservancy District to rehabilitate Memory Grove following its destruction by a tornado (Salt Lake Tribune and Jim Woolf, Sept. 24th, 1999). On September 30th, 1999, City Director of Public Utilities LeRoy Hooten, Jr. announced the construction of a six-by-six foot concrete pond near Memory Grove in which dogs can wade (Salt Lake Tribune). Dogs entering City Creek’s stream have quadrupled the coliform count. On July 20st, 2001, City Planning Director Stephen Goldsmith noted that a gate had been added at Memory Grove to control traffic (Salt Lake Tribune).

In 2003, a Korean War Dead monument was added to the park (Plaque visited 2017). (The Vietnam era memorial is on the west capitol lawn. The Iraq Afghanistan war memorial is in Cedar City, Utah.) 141 Utahans died in Korea (Salt Lake Tribune. Apr. 25, 2013). 370 Utahans died in Vietnam (Virtual Wall). Through 2010, an unofficial count for Iraq and Afghanistan was 39.

A stone monument listing 6 Utah Medal of Honor recipients was also added. Recipients include George E. Wahlen, after whom the Salt Lake Veteran’s Hospital is named. Medic Wahlen was shot several times during the Battle for Iwo Jima such that he was unable to walk. Nonetheless he crawled across a battlefield under enemy fire to give assistance to other wounded soldiers. Whalen survived. George T. Sakato, a member of the WWII Nisei battalion led a charge against repeated enemy attacks. Brian Miles Thacker, still living, defended Firebase 6 in Vietnam as it was being overrun by North Vietnam regulars. He stayed behind and provided cover fire that allowed all other base members and wounded to evacuate. He evaded the NVA as the base was overrun and made his way back to US held territory through hostile ground. Jose F. Valdez’s WWII platoon of six was attacked by German tank. Valdez drove the tank off using only a carbine. The German army counter attacked with two companies (160-500 men). Valdez volunteered to and stayed behind to hold off the attack, allowing his platoon mates to escape. He was shot more than once, but still managed to evade capture and return to US lines. Valdez later died from his wounds sustained in the counter attack.

Battle deaths, meaning military deaths on both sides of a conflict plus collateral civilian deaths, were: WWI, 17 million; WWII, 60 million; Korea, 1.2 million; and Vietnam, 2 million (Lacina and Gelditsch 2005), or a total of about 80 million persons.

On February 1st, 2011, the Salt Lake Rotary Club, who built Rotary Park in upper City Creek Canyon in 1921 and who renovated the Ottinger Hall in 2005, the former fireman’s association meeting house near Memory Grove, celebrated its 100th anniversary (Salt Lake Tribune and Mike Gorrell, Feb. 1st, 2011). Ottinger Hall is now a youth center.

In counterpoint to the Memory Grove memorial to war dead, Salt Lake City hosts another unique memorial indirectly related to the non-combatant victims of war: the International Peace Gardens in Jordan Park at 1000 South and 900 West. The Peace Garden was conceived in 1939 by Mrs. Otto Wiesley and the Salt Lake Council of Women as a beautification project for the 1947 Utah Centennial (Salt Lake Council of Women 2017). Construction was halted by WWII, resumed in 1947 after the end of WWII, and the peace garden was dedicated in 1952. The garden contains monuments donated by 28 different countries. The United States’ “Peace on Earth” statute in the gardens features heroic images of mothers that was created by Mormon sculptor Avard T. Fairbanks. The statute is dedicated to “the hope we can leave a more peaceful future to our children.” Inscriptions on the statute read “Our Hope to the Children”, “Peace on Earth”, and “The Dawn of a New Era”. After the 2002 Winter Olympics, 84 “Peace Poles” were installed at the entrance to the gardens: one for each country participating in the winter Olympics. (Other sources list 78 countries as participating in the 2002 olympics.) There are about 156 similar peace gardens and another 146 larger peace parks around the world (peace.maripo.com)

Political scientist J. R. Rummel of the University of Hawaii (d. 2014) specialized in systematically counting civilian non-battle deaths – those deaths in conflicts not between two states – and he total an astounding 262,000,000 losses from 1900 to 1999 (Rummel, 1994, 1997, 2002). Examples include the Khmer Rouge in the 1970 and Stalin in the 1930s. The world population increased by 5.5 billion persons between 1900 and 1999, that is the net of live births less deaths. Therefore, Rummel’s 262 million represent at at most 5 percent of all persons alive during that century. Using more sophisticated estimates, some experts place the figure at less than 1 percent of all persons who were alive during the twentieth century.

Many more days are devoted in the United States to remembering military battle dead as compared to civilian battle dead, other civilian victims of conflict violence or life in general. Memorial Day is one of the three official United States’ holidays that are related to war and the solemn remembrance of war dead: Memorial Day (May 30th), Independence Day (July 4th), and Veterans Day, (November 11th). Veteran’s Day was originally Armistice Day that remembered the war dead of World War I, and four other days are now observed primarily by the United States military: Pearl Harbor Day (December 7th) marks the beginning of World War II; the less well-known Armed Forces Day (May 21st); D-Day (June 6th) marks the landing of allied forces on the French coast; and V-J Day marks the end of World II (September 2nd). German Remembrance Day, the German day for remembering war dead, is observed annually around November 14th at Fort Douglas cemetery at the monument to 41 German WWII prisoners of war who died in Utah. From the view of First Peoples, Columbus Day (October 9th) marks the beginning of Euro-American genocide against native Americans and is also a day of remembrance. From the view of United States working people, Labor Day (September 4th), celebrates a compromise that ended violent conflict between labor and upper classes. Although not widely observed in the United States, International May Day celebrations began in Chicago in 1886 with celebration of labor’s declaration for the eight-hour work day, but was quickly followed by the violence of the Haymarket Massacre on May 4th. Today, it is observed worldwide as a day commemorating the struggle between labor and capital.

In contrast to the seven days commemorating war dead, two unofficial and one official United States holiday celebrates life and nature: Earth Day (April 22nd), Arbor Day (April 27th), and Christmas near the first day of winter. These are supplemented by two other unofficial days related to the movement of life through the seasons: the first day of spring and autumn. No official United States holiday commemorates civil battle dead or other civilian victims of conflict violence. In 1981, the United Nations established the International Day of Peace on September 21st of each year (United Nations, 1981).

On May 29th, 2009, Utah Governor John Huntsman, county Mayor Peter Corroon and Salt Lake City Mayor Ralph Becker held a press conference in City Creek Canyon to announce a new planning process administered by Envision Utah called “Wasatch Canyons Tomorrow” (Salt Lake Tribune). On May 29th, 1993, James R. Cook, in a letter to the editors of the Salt Lake Tribune, proposes to transform Traverse Ridge at the south end of Salt Lake Valley into a nature reserve similar to City Creek Canyon at the north end of the valley. (By 2017, Traverse Ridge was transformed in a luxury subdivision). On May 29th, 1914, City officers visited the newly completed City-Creek Wasatch Boulevard in anticipation of its opening on May 30th (Salt Lake Telegram, Salt Lake Tribune). City Creek Canyon Road has been widened to Pleasant Valley (id).

Spring Bird List

3:30 p.m. In the morning I am woken by the cawing of an American crow (Corvus brachyrhynchos) standing outside my window, but then I drift back off to sleep. Around noon, neighbors are buzzing over their photographs of a common Red fox (Vuplus vulpes) hunting mice in the city cemetery about one-third of a mile from my home and on the south-City side of the east-south canyon ridgeline.

In the afternoon, the cold snap of the last few days has ended and the canyon is again warming into the sixties under blue, ideal spring skies. Driving into the canyon along Bonneville Drive, the grasses have reached up to three feet high, but in the canyon they remain between one foot to eighteen inches in height. Along Bonneville Drive, young Curly dock plants rise, but there are none in the fields at mile 1.5. Arrowleaf balsamroot has noticeably disappeared from the surrounding hillsides through mile 1.5, and its yellow color has been replaced by the duller yellow of fields of Dyer’s woad. Along the first mile, where a few days ago there was a single Sticky Wild Geranium, there are now ten, and four blue penstemons are blooming. The other major blossom are the white inflorescences of chokecherry bushes or trees. Blue is the color of canyon near the stream, but at the Pleasant Valley lower field, I scan the surrounding hillsides for a hint of Arrowleaf balsamroot. There is none, only the green of the balsamroot’s wide bases surrounded by wide swaths of Dyer’s woad. A pattern repeats in the many sun-exposed small gullies that lead to the western salient’s ridgeline and below the eastern salient’s cliffs: Groves of green Gambel’s oak or Red Maple fill the damp soil or seeps along side canyon gullies, but where the side canyons begin to flare out, the dryer soils, formerly covered with balsamroot, are now covered in Dyer’s woad. At lower elevations along the western slope above the Pipeline Trail and above Bonneville Drive, some balsamroots remain in bloom, but their numbers are rapidly dwindling from their shriveling flowers.

Butterflies are recovering in the rising heat. Yesterday’s Western tiger swallowtail and Desert Elfin butterflies are joined by a few Spring Azure and White cabbage butterflies. About eight new, small and black unidentified butterflies appear. They move too fast to see any detail. Two examples of a new unidentified small black spider are on the road, and a small black ant is carrying a whole insect pupae, about eight times it size, back to its underground ant lair. Common houseflies are active on the road, and a larger Blue-eyed darner dragonfly patrols up and down the road. Along the Pipeline Trail, I flush out two Mormon crickets. Instead of red underwings (May 8th), they now flash muted orange underwings.

Where the chokecherry bushes are warmed by the sunlight, they are the buffet for the insects. The best of these is along the Pipeline Trail near mile 0.9, and the chokecherry bush is covered in about seventy bees, flies and a American Lady butterfly. The bush sits near a seep in a bend in the trail. It is in a large-tree shaded area, but a single shaft of light penetrates and warms the bush and its nearby air to fifteen degrees more than its surroundings. Another shaded chokecherry bush about fifteen feet away is ignored by these flighted insects. On the chokecherry inflorescences there are also two types of flies, one large and one small, and three types of bees, including a red-rumped worker bumble bee, wild common honey bee (Apis var.) and one of two Utah varieties of the Carpenter bee (Xylocopa californica) (Hodgson and Trina 2008). Near this seep, a tiny unidentified slug, about 1 centimeters by 3 millimeters in diameter crawls up the trail, and I help to the mud next to the seep. Three other chokecherry bushes fifty yards up from Guardhouse Gate and a full chokecherry tree at picnic site 4 are similarly covered, but to a lesser degree. These are also sunbathed.

A flock of four distant raptors circle and glide up canyon. Birds along the first 1.5 miles of road can be divided roughly into seven neighborhoods or groups: at Guardhouse Gate, at road mile 0.4, at road mile 1.0, the lower half of Pleasant Valley, mile 1.1 to 0.9 of the Pipeline Trail, the Trail between mile 0.9 and 0.5, and the Trail between mile 0.5 back to the Gate. There are more calls than yesterday, with between 5 to 10 birds in each neighborhood. By sound alone, I can pick up a few of the easiest out of a chorus of ten different songs: the Lazuli Bunting at the Gate; a Song sparrow and an American Robin near mile 0.5; a near road mile 1.0,; and a Black-chinned hummingbird flying near Trail mile 1.0. I have gathered recordings of about 40 spring birds on my smart telephone, and have begun to replay them constantly in the hopes of building a beginner’s skill for distinguishing their songs. The avian soundscape is being to make more sense to my untrained ear.

As I reach Guardhouse Gate, there is a young woman standing 50 feet from the road, half obscured by blinds made leafed branches of Gambel’s oak, and she is singing gospel and folk songs in a loud but beautiful voice. She has long-black hair, is wearing a short, summer dress of yellow printed ethnic cotton, and is illuminated by that special warm light before dusk. Several strolling couples and myself discreetly walk up to the side of the road for an impromptu concert. For a moment, my mind is momentarily transported back to my adolescence and a similar scene from 1971. After a few minutes, everyone wanders away, leaving her to practice her singing without disturbance, but grateful for a unique moment.

The slate of spring canyon birds for this year has sufficiently filled out that a list is timely. The 54 species represented shows the diversity of bird life that is finding living niches in the canyon and making connections between its plants and insects.

The Wasatch Front Mountain Range has not seen a decline in the number of avian species since the Euroamerican arrival, but no opinion is expressed on any decline in the population of these birds. As noted before (March 4th), ornithologist Robert Ridgeway conducted a survey of birds in Parley’s Park at the summit of Parley’s canyon about ten miles from City Creek Canyon between June 23rd and August 16th, 1869 (Rawley, 69-79). He found 116 bird species. Comparing Ridgeway’s list with Cornell Ornithology Laboratory’s Ebird List for City Creek Canyon for 1900 through 2017 shows 149 species (Cornell Ornithology Lab. 2016, Cornell Ornithology Lab. 2017). For the years 2000 to 2017, 147 species are listed, and for 2012 to 2017, Cornell totals 143 species (id). There are some minor non-duplicates between the historical and modern lists. The Yellow-bellied sapsucker is not currently found in City Creek, and the range of other birds has changed. Birds such as sandpipers and Sandhill Cranes do not presently frequent City Creek but can still be found at the Great Salt Lake’s beaches and marshes. But essentially, the avian diversity of Ridgeway’s 1869 mountain birds is still intact at City Creek Canyon after 148 years.

That the diversity of Utah’s many migrant birds is stable is also shown by Parrish, Norvell, and Howe of the Utah Division of Wildlife Resources in a multi-year study from 1992 to 2005 (Parrish et al. 2007; Norvell, Howe and Parrish 2005). Examining 202 statewide bird species over 12 years at 37 Utah sites, Parrish and colleagues found no significant trend in mean annual species richness (id, p. 27, Fig. 4).

On May 20th, 2014, Salt Lake Fire Captain Scott Winkler reports that the City has spent $650,000 on six new firetrucks specialized from fighting fires in grass brush areas around luxury homes near Ensign Peak and in City Creek Canyon (Deseret News). On May 20th, 1903, the City Council and Mayor considered issue bonds to construct reservoirs including a 5,000,000 gallon reservoir at Pleasant Valley (Salt Lake Telegram). On May 20th, 1901, an estimated three-hundred people went up City Creek Canyon, one-thousand to Liberty Park, and three-hundred for recreation (Salt Lake Tribune). On May 20, 1896, the City council considered moving the responsibility for maintaining City Creek watershed protection to the health department and the duties of the City Creek Canyon patrolman were described (Salt Lake Tribune). There were five full-time patrolmen. Three men are employed at the lower Brick Tanks keeping the screens clear of debris. Two men are employed for 12 hours per day to service the upper high-line tank screens and to patrol the upper canyon to prevent sheep grazing. Two other men service the Twentieth ward tank and the Capitol Hill Reservoir (id). City Creek has been rip-rapped for two miles above the lower Brick Tanks. On May 20th, 1896, high spring run-off has turned City Creek into muddy water and the water is clearing (Salt Lake Herald).

Winter Interlude

3:30 p.m. The jet stream is again broken and chaotic (May 8th). This time the discontinuity stations a huge low pressure system, shaped like some misplaced galaxy with great arms separated by open spaces, over Idaho, and this weather system brings cold arctic air back into the canyon. Temperatures drop over night into the thirties and only reach the high forties during the day. Banished winter makes returns. Throughout the morning, the sky, between the arms, alternates with an hour of sunlight that turn again to dark skies and rain. As I enter the canyon, light snowflakes, miniature versions of winter’s mature form, fall from the sky, and turn to a light rain. The high walls of the canyon are again covered with a light snow and Little Black Mountain is frosted white. But the snow is deceptive. Along the road only a few patches remain on the leaves of the broadest ground plants. On the hillsides, the Arrowleaf balsamroot blossoms reflect white, not yellow, but this will all be gone in another hour. Next to the winding road, the plants are invigorated by cold, and groups of songbirds sing louder, not softer, in defiance of the prior season. Two bonded pairs of mallards swim the flood retention pond. Three groups of songbirds collect at the Gate, near mile 1.0 and again in Pleasant Valley. A single raptor is soaring up-canyon along the salient. Butterflies are vanquished.

At Pleasant Valley, the 50 meter diameter Gambel’s oak grove has now fully leafed out. There members of Utah State University’s Utah Conservation Corps have returned (Oct. 16th) for further work on their starthistle field abatement. Last year’s removal of the starthistle plants has made a lush, green field in lower Pleasant Valley, but it has given the myrtle spurge an opportunity to return. Today, they pull the spurge in the field and on the hillside surrounding the oak copse. It is hard, labor-intensive work, perhaps impractical, and I can see the temptation that biologists in the past had to use either chemicals or biological controls in the form introduced invasive insects. Both techniques end with unanticipated, adverse results. The City has already tried chemical sprays on the starthistles (Salt Lake Tribune, May 20, 2008), but that failed at Pleasant Valley.

I revisit the stretch of flat stream near picnic site 11 that I have named Rivendell (Jan. 19). I expect to find the entire area flooded. The stream has doubled in size to about 18 feet across and 18 inches in depth, but its surface runs smoothly downstream. There is a same sandy beach, barely two feet wide, at the water’s edge, and there deep hoof prints tell of mule deer coming for a drink earlier in the day.

Returning down canyon by the Pipeline Trail, the Sun comes out as the next arm of the low pressure system arrives. A Broad-tailed hummingbird flutters in the oaks, and another chorus of about eight songbirds starts up again. On the road, the warmth entices a bright yellow Western tiger swallowtail butterfly out of the bushes.

On May 17th, 2006, Sarah Grant is training in City Creek for a 3,000 mile cross-country fund raising ride to benefit Splore, a local disabled outdoor program (Salt Lake Tribune). She plans to raise $30,000. On May 17th, 1926, twenty-four men and women of the Wasatch Mountain Club hiked up City Creek to “Scotts Peak” at the canyon’s headwaters (Salt Lake Telegram). On May 17th, 1919, City Park Commissioner George Y. Wallace argued for the creation of a scenic boulevard up City Creek Canyon and then along 11th Avenue and the bench to attract the new automobile tourism (Salt Lake Telegram).

Filed under: Gambel's Oak — canopus56 @ 2:12 pm

Sister Oak

2:00 p.m. At Pleasant Valley, a favorite copse of Gambel’s oak, about 50 meters in diameter that sits on a western hillside has leafed-out at once. A week ago, it was bare. Such simultaneous leaf-out and abscission (leaf dropping) in a small tree grove is indicative that the trees are genetically identical. Back on February 14th, I speculated on whether Gambel’s oaks, like aspen trees, form large monoclonal groves. Gambel’s oak mostly reproduce asexually, but they switch back to sexual reproduction in response to a forest fire (Feb. 10th). Although many of the oak groves in the canyon have a 50 meter elliptical shape, as this grove does, along the Pipeline Trail, there are long stretches of slopes covered in dense unchanging oak trees. Between the beginning of the canyon at Guardhouse Gate and higher altitude groves at Pleasant Valley, there is a clear ordered geographic sequence of increasing dates of Gambel’s oak leaf-out as altitude increases. But the leaf-out in the higher copse and in lower larger groves of the oak occur in unison at each location.

The snow pack is completely gone from Little Black Mountain and is almost gone from Scott’s Hill. From the valley floor, it still remains on Grandview Peak.

In response to an inquiry made back in February to the Utah Native Plant Society, a biologist-researcher responded on my speculation on whether Gambel’s oak could form monoclonal mega-plants like Utah’s aspen grove named Pando. Chalmers at the University of Utah and colleagues found a statistically significant association between the genotypes of eleven Gambel’s oak clumps about 12 meters in diameter at nearby Red Butte Canyon and their leaf abscission date, but no relationship was found between their geographical distance and their leaf-loss date (Chalmers at al 2015). One of the study’s researchers, Kohl at Utah State University, was perhaps being kind to me in suggesting that he could not rule out larger-sized genetically identical Gambel’s oak mega-plants, but he felt there was little possibility of obtaining funding to test the question.

On May 9th, 1999, the successful completion of the Memory Grove Foundation’s program to repair monuments in City Creek Canyon was reported (Salt Tribune). On May 9th, 1907, Finacune, a nationally known boxer, arrived in Salt Lake to train in City Creek Canyon for a match set in Ogden (Salt Lake Telegram). Billy (William J.) Finacune (b. 1882) fought many title contenders around the turn of the century. During 1907, his last two fights were against Dick Hyland and Mugsey Shoals in Ogden, Utah.
