July 21st, 2016 – End of Cyclical Year, Revised and Reposted

Microorganisms, Moss, Lichens, Glaciers, and Climate Trends

(Revised and expanded after lichen identification completed.)

3:30 p.m. It is another day intense summer heat, and as I pull into the parking lot, I take notice of a large Limber pine (Pinus flexilis at the lot’s end, south of the row of cultivar Horsechestnut trees. The Limber pine, Narrowleaf cottonwoods and the Horsechestnuts are among the largest plant organisms in the canyon, excepting some of the 50 foot diameter copses of Gambel’s oaks that may be one large, genetically identical sister plant. A bizarrely twisted, immature Limber pine hides behind to the east of side of the Guardhouse Gate building, and just past the gate, another conifer, a mature 70 foot tall native Engelmann spruce (Picea engelmannii). Key taxonomic differences between the two is that round pine needles occur in groups of two and flat fir and spruce needles are single. At mile 1.7 at picnic site no. 12. There a forty foot tall Rocky Mountain juniper (Juniperus scopulorum) is flanked by two taller Engelmann spruce trees. Although native to northern Utah, these three trees have been artificially planted to provide shade for picnic area.

Jogging up canyon about 100 yards up from the gate, I pass a deadly Bittersweet nightshade plant with small 1.5 inch green fruit. Splitting one of the fruit open, it is full of 1 mm bright orange larvae, and testing a few more, they are all infected. Given the number of young children that pass this spot, this is probably not a good place for a poisonous plant.

In the heat, I jog alone through an empty road, except for bicyclists. Near mile 0.3, sounds in the Gambel’s oak forest undergrowth betrays an yearling Mule deer stares back through the leaves. It is waiting for me to pass, so it can reach the stream and water. A bicyclist streaks unaware of its presence. A slight anabatic up-canyon wind provides a brief relief.

Beginning at mile 0.5 and the pond at picnic site 5, I collect the sponges placed in the stream and seeps on July 15th. The sponges have been collecting microorganisms for several days. I have looked at water samples from the stream under a microscope several times since May, but have never seen any microorganisms. That is a testament to how pure City Creek Canyon water is. My microorganism observing guide suggests using the sponges to trap organisms over time. The sponges also provide a protected framework that might appeal to microorganisms by providing shelter. The first sponge was located below the pond at picnic site 5, and it was placed under a cover of rocks such that stream water would continuously flow through the sponge. The first from the stream is a dark brown – a good sign. The second collected from the seep below picnic site 6 and the third is retrieved from the watercress seep also below picnic site 6. All three are a dark brown-grey color; the sponges have worked.

At the seep below picnic site 6, the Horsemint is in full bloom, and I count 32 Cabbage white butterflies feeding on them. A single Central bumble bee (Bombus centralis) collects among the butterflies. These are joined by an orange Mexican queen butterfly. I stand mesmerized by the glade for a few minutes. Nightshade is now also blooms in this glade.

Carpenter bee (Xylocopa californica) reappear after their first spring flight. Uniquely, they fly in a circular pattern closely around me twice, and having rejected me as potential food, they fly off with purposeful intent.

Proceeding again up canyon through the heat, only a few birds are heard at some distance from the stream. I cannot distinguish their calls, except for the nasal cawing of a Red-breasted Nuthatch (Sitta canadensis).

At mile 1.1, I stop where a large rock ledge overhangs the stream and admire a tremendous cottonwood cross, a Populus angustifolia x fremontii S. Wats. This 100 foot tree with a twenty-four inch trunk betrays it hybrid nature through two suckers, each 8 inches in diameter at the base. The parent tree has ovate leaves typical of the cross. Those leaf forms continue on one of the suckers, but at its very tip is one perfectly formed triangular Fremont popular leaf. Mid-way up the second sucker, that is also covered in hybrid leaves, is a bracket of perfectly formed thin Narrowleaf cottonwood leaves. This tree must be at least 100 years old, and perhaps it is older and witnessed the arrival of the Euro-American colonists in 1847. At a few minutes of enjoying this tree, I notice that it is looking back at me. More precisely, another Mule deer is on the rock ledge on the far side of the stream, and it is intently following me. I continue up canyon so it can reach water unmolested.

At mile 1.2, I turn down-canyon on the Pipeline Trial in order to photograph some of the lichens on rocks that line the trail down to where it is perpendicular to the Red Bridge and Chimney Rock. The Gambel’s oaks that border each side of the trail are covered in a ubiquitous dusky orange lichen that is found throughout the canyon. Here the rocks are principally volcanic breccia or limestone conglomerates. The first rock has lichens that are three inch diameter turquoise dollops with raised fruiting centers. The second rock has a large turquoise dollop on one corner and fire yellow bright lichen on one face. This rock also has small dark black lichen circles. The third rock has bright orange circles with darkened brown centers. The fourth has similar bright orange two inch dollops with fruiting orange centers. This same orange rock lichen is common in the canyon. For example, it covers parts of the rock bridge at Weeping Falls near mile 5.2. This bright orange lichen only appears on rocks, and its dusky orange brother keeps to the trees. Near the end of this segment, a gully provides more shade an water. Here, the rocks are covered in complex moss complexes, and unidentified green-black small-onion like moss with fine white hairs.

Continuing up canyon to a western gully near mile 2.3, there is another slope with favored lichen rocks. Here the rocks are sandstone based. In the gully, the first rock is a kaleidoscope of circular lichens colored bright orange, turquoise, and black. The next rock is covered with a bulbous green-black moss with fine white hairs. This is followed by a rock covered in turquoise-green lichen that has a darker brown center. Finally, two foot square areas of an unidentified green-black bulbous lichen attach to a rock ledge’s horizontal surface. Looking over some of my other lichen photographs above milepost 5.0, two prominent upturned limestone ledges stick out next to the road. On these a montane grey-milk lichen that look like delicate leaf petals cling to the stone.

This is all a riot of color mixed with abstract design. Lichen are oldest and, for me, they embody the most alien of terrestrial life. I also hold them in the highest respect because they are all a form of extremophile. They thrive on canyon rocks that both bake to temperatures over 150 degrees during the summer, and they continue to reproduce during the subzero cold of deepest winter. They live on the surface of barren rocks and take all that they need from the passing air and rain. And, what else the need in terms of minerals, they obtain by dissolving the solid rocks to which they attach. Moss are less of an extremophile, but tree moss are one of the few plants that continue photosynthesis through the depths of winter (January 10th).

Returning down-canyon near mile 1.3, ahead, I again here the screeching of a Peregrine falcon. Two falcons are chasing two unidentified hawks away from the sandstone cliffs on the east wall of the canyon near mile 1.0. One falcon easily chases a hawk up canyon and over the ridge. The second hawk begins to climb in lazy, large circles, and the remaining peregrine follows. The peregrine raises higher and then stoops the hawk, all the while screeching loudly. This continues for about 15 minutes. At times I loose sight of the pair as they circle overhead with the Sun behind them. The spring sky is a deep blue, but today, the summer sun makes the atmosphere a white turquoise.

Continuing down-canyon, at picnic site 5 where I collected one sponge, an innovative young couple using long lengths of climbing webbing, have suspended two bright Central American woven hammocks over the stream. They lay side-by-side enjoying the stream-cooled air.

At Guardhouse Gate, there are the cut fireplace-sized remains of a large tree. A quick count of its rings indicates the tree is over one-hundred years old. As the the city cuts down infirm trees in the canyon, they leave the carcasses here as free firewood. The cause of this tree’s demise can be seen in one segment of log – it is riddled to the inner pith with boring beetle tunnels. To supplement my gathering of water borne small life, I also collect from the logs’ surfaces, samples of Green tree moss (probably Orthotrichum sp.) and of orange, black and turquoise lichens.

The lower flood retention pond is full of algae mats. A family of mallards graze on the greenery. The chicks, who a few weeks ago where only four inches long, are now twice that size.

At home, I examine water from the three sponges in under a microscope at 60 power of magnification in order to see some of the smallest plants and animals of the canyon. All of the samples consist mostly of bits of algae, some of which are strung on the ends of mold filament, pulverized bits of plant, and specks of silica. No moving protists are seen. A few rectangular-celled with diatoms with well-defined glass-like walls of the genus Fragellaria are found. Two circular diatoms of the genus Stephanodiscus are seen. Finally, a single, transparent perfectly formed leg of an insect exactly fills the eyepiece and then floats away. This is clean City Creek water.

At home and through the hand-lens, the leaves of the moss, which are present both on trees and on rocks in the stream, reveal their earlier evolution as compared to the leaves of the surrounding trees. They are thin and transparent sheets of green cells, and they lack any vascular features found in true leaves.

Under the hand-lens, where the black lichens interface with the tree’s bark, a separate white hyphae through which digestion occurs. Lichens are composite organisms of algae or green bacteria living symbiotically with fungi. Through the hand-lens, one can see two colors, representing the two organisms in the turquoise and orange lichens. The turquoise portion of the turquoise lichen is also surrounded by white hyphae. The second color is green, and through the lens, these resolve as small bits of algae. That lichens exist on almost all of the trees in the first two miles of road is a good sign. Lichen are sensitive to air pollution and will disappear if Salt Lake’s air quality severely deteriorates over a long period.

The length of the day have changed noticeable from June 20th’s summer solstice. Sunset comes an hour earlier around 9 p.m.

St. Clair, Newberry and Nebeker (1991 and 1995) provide a comprehensive list of Utah lichens. They and Flowers (1954) describe which species of lichen are common in various northern Utah habitats, including for the scrub oak forest of Gambel’s oaks, the higher subalpine habitat of Quaking aspens, and the montane habitat of conifers. Brodo of the Canadian Nature Museum and Sharnoff and Sharnoff of the Missouri Botanical Gardens published the definite photographic identification guide for lichens: their massive 2001 “Lichens of North America”. They note common lichen species for the Gambel’s oak forest include Lecanora hageni, Phaeoplzyscia orbicu/aris, Physcia adscendens, Physcia dubia, Physcia stellaris, Plzysconia grisea, Xanthoria fallax, and Xanthoria polycarpa. Using these sources, my descriptions and photographs match with the following scientific names:

List of Lichens

• Hooded sunburst lichen (Xanthoria fallax): This is the dusky-orange lichen that covers most of the Gambel’s oak trees in the canyon (Brodo, Sharnoff and Sharnoff, 744).

• Pin-cushion sunburst lichen (Xanthoria polycarpa): This is the bright orange lichen that covers many rocks in the canyon, including the stone bridge at mile 5.2 (Brodo, Sharnoff and Sharnoff, 746).

• Stonewall rim-lichen (Lecanora muralis): This lichen was the even-toned yellow-green (turquoise) circles on rocks along the Pipeline Trail (Brodo, Sharnoff and Sharnoff, 383)

• Sagebrush rim-lichen (Lecanora garovaglii). This is the yellow-green (turquoise) lichen with a darker green center on a rock along the Pipeline Trail (Brodo, Sharnoff and Sharnoff, 380).

• New Mexico rim-lichen ( Lecanora novomexicana): This darker yellow-greenish lichen with yellow fringes was found in the gully near mile 2.2 (Brodo, Sharnoff and Sharnoff, 384).

• Gold cobblestone lichen (Pleopsidium flavum): This is the bright yellow lichen on one rock along the Pipeline Trail. (Brodo, Sharnoff and Sharnoff, 578).

• Powder-tipped rosette lichen (Physcia dubia): This is the delicate leaf-shaped lichen on the limestone vertical fins near mile 5.0 (Brodo, Sharnoff and Sharnoff, 554).

Like today’s Great Salt Lake (May 26th), ancient Lake Bonneville’s water levels and glaciation of the Salt Lake’s canyons at the end of the last ice age gives clues as to the climate of the Salt Lake valley and the canyon. That record is hidden within the valley’s rocks and trees. In 2015 and updating a prior study from 1997, Oviatt at the University of Kansas reconstructed date ranges in which ancient lake rose and fell by radiocarbon dating organic material in tufa deposits along the lake’s former shorelines. He concluded that Lake Bonneville began its rise about 30,000 years ago (id., Table 1). Between 15,000 and 18,000 years ago, Lake Bonneville reached its maximum height at about 5,100 feet, or near the northern end of Pleasant Valley in the canyon near mile 1.7. Following the failure of the Red Rock ice dam in Idaho, the Lake drained to the Provo Shoreline, which is Bonneville Drive and 11th Avenue in the City. Other the next 15,000 years, the lake gradually declined to the current level of the Great Salt Lake (id).

In 2011, Laabs, Marchetti, and Munroe and colleagues used residual Beryllium 10 isotopes in rocks, taken from the glacial moraines in Little Cottonwood Canyon in Salt Lake valley and American Fork Canyon in Utah valley, in order to date when glaciers retreated up from the ancient lake’s shores. An ongoing question existed amongst geologists, based on conflicting earlier studies, concerning whether the Salt Lake glaciers receded before, coincident with or after the end of the last Ice Age and-or before, coincident with or after the end of the peak level of Lake Bonneville. Figure 1 of their study shows the area of glaciation stretching from American Fork to the south and Farmington, Utah in the north, thus, including City Creek Canyon. They concluded that glaciers covering the Salt Lake valley canyons started to retreat 15,700 plus or minus 1,300 years before the present, either during or shortly after the maximum 5,100 foot shoreline height of ancient Lake Bonneville. Their confidence interval overlaps the 15,000 to 18,000 years before the present found by Oviatt for the maximum height of Lake Bonneville. Deglaciation started about 4,000 years after the end of the continental Ice Age at 18,000 years ago. Because the lake reached its maximum and retreat of the local glaciers started after the end of the Ice Age, Laabs, Marchetti, and Munroe et al concluded that the local climate between 18,000 and 15,000 years ago was wetter than thought by prior geologists.

That there were glaciers in City Creek Canyon below Grandview Peak and at the canyon’s final hanging valley (September 8th) seems evident from an examination of any terrain map and hiking the canyon. But to my knowledge, there are no studies dating the glacial deposits in City Creek Canyon. Van Horn and Crittenden’s geologic map shows no surficial glacier features (Van Horn and Crittenden, 1987, U.S.G.S. I-1762). Perhaps there was a lighter ice sheet over the canyon 15,000 years ago, but it was insufficient to crave the bedrock.

The Engelmann spruces and other pine trees that live in association with the spruces, tell the history of Salt Lake valley’s and the canyon’s climate for the last 13,000 years before the present. In Little Cottonwood Canyon, Engelmann spruce share the glacial scoured hillsides with Limber pine (Pinus flexilis). Engelmann spruce is more tolerant of wet earth and colder soil temperatures, and Limber pine is more tolerant of dry earth and warmer soil temperatures. Thus, as climate changes occur over thousands of years, the relative amount of pollen left in soil layers beneath their canopy gives a general indication of weather in the distant past. In 1979, Madsen and Currey at the University of Utah used a bog in Gad Valley near Snowbird Ski Resort to reconstruct Utah’s late Holocene climate (Madsen and Currey 1979). Based on moraine deposits, the maximum extent of glaciation that extruded glaciers into the Salt Lake valley floor occurred about 25,000 years ago. After a period of warming, a second smaller glacial period ensued and Madsen and Currey, using the bog at Gad Valley places that around 12,500 years ago. Then glaciers within Little Cottonwood Canyon retreated and disappeared. A similar bog in Albion Basin at the top of Little Cottonwood is dated at 9,500 years (id, 258). Using the ratio of Engelmann spruce and Limber pine in the Gad Valley bog, Madsen and Currey were able to reconstruct the relative climate of the canyon, and by extension the Salt Lake Valley and City Creek Canyon, for the past 12,500 years. Between 13,000 and 8,000 years before the present, the valley’s climate was cooler and wetter than today. Between 8,000 and 5,000 before the present, advancing Limber pines indicate a warmer and drier climate than today. Then there was a brief period in which temperatures greatly declined, followed by a quick warming and a gradual decline to today’s cooler temperatures with respect to the 13,000 year mean (id, at Fig. 6 and 265). In contrast, precipitation has been on a gradual decline for the last 6,500 years and is currently near the 13,000 year mean (id). These are consistent with Grayson’s climate divisions for the Great Basin Holocene generally: 10,000 to 7,500 years before the present (early), 7,500 to 4,500 years before the present (middle), and 4,500 years before the present until today (late) (Grayson, Chap. 8).

Over the last 4,500 years, a picture of trends in Salt Lake City’s local climate can be developed from tree ring, Gad Valley bog pollen, and other climate research. Since 4,500 years before the present, there was a brief period in which temperatures greatly declined, followed by a quick warming and a gradual decline to today’s cooler temperatures with respect to the 13,000 year mean (Madsen and Currey, Fig. 6 and 265). It is now colder than average than over the last 13,000 years. The Little Ice lasted from about 1300 C.E. to 1850 B.C. There were highly variable swings in temperature during this time, but those changes were not global, but regional (Solomon et al 2007; Houghton et al 2001). In Utah, the Little Ice Age ended in 1850 and was followed by the most severe winter in Utah history, the winter of 1855-1856.

Since 4,500 years before the present, precipitation has been on a gradual decline for the last 6,500 years and is currently near the 13,000 year mean (Madsen and Currey). From 1492 to the present, the tree rings show that persistent, severe droughts were far more prevalent in the distant past than in the 150 years of Euro-American presence in northern Utah (Bekker et al 2014). Variability in Salt Lake City precipitation since the 1960s, including severe drought in the 1960s and peak flooding in the 1980s, is tied to the Pacific Quasi-Decadal Oscillation, an 11 year cycle of drought and heavy precipitation tied to ocean temperatures off the coast of California and Japan. The level of the Great Salt Lake acts as a recorder of climate, and the Lake’s level has been recorded continuously since 1875 (USGS, 2017a, USGS, 2017b). In the summer of 2016, it dropped to a new historical low of 4,190.1 feet (id).

In 2010, Wang and colleagues at the Utah State University associated the Pacific Quasi-Decadal Oscillation (PQDO) with a northern Utah three-year leading precipitation and a six year leading level of the Great Salt Lake (Wang, Fig. 4 at 2166). In the association with the level of the Great Salt Lake, PQDO warm phase peaks are associated with the lowest lake levels and PQDO cool phase troughs are associated with the highest lake levels. In 2013, DeRose, Wang and colleagues used tree rings to reconstruct the level of the Great Salt Lake back to 1429, and they associated the lake’s level to the pacific oscillation back to 1700 (DeRose 2013). In recent years, the PQDO has been good for Utah. While California has suffered severe drought, the PQDO has kept annual precipitation relatively higher in Utah (IWWA Project).

The PQDO has not had a phase change since 1997 and the change to a heavy precipitation pattern is overdue. Despite heavy winter snowfall in the high mountains during the winter of 2016-2107, Utah remains in an extended drought with unseasonably warm summers.

Future uncertainty is added by the effect of global warming. Has global warming disrupted the Pacific Quasi-Decadal Oscillation? What will its future impact be? However, even excluding global warming, Salt Lake City and Utah are on a path towards relatively hotter weather and declining water supplies as compared to the past.

On July 21st, 1942, the City banned the entire north bench of Salt Lake City to entry due to fire hazard, but access to City Creek Canyon would remain open (Salt Lake Telegram). On July 21st, 1906, the Deseret Evening News published a picture of a 10 foot snow bridge across City Creek Canyon about nine miles up the canyon. On July 21st, prize fighter Tommy Reilly trained by taking a long run up City Creek Canyon (Salt Lake Telegram). On July 21st, 1903, about 100 Ute Tribe members gathered for an annual celebration at the mouth of City Creek Canyon (Salt Lake Herald). (In the present, the Ute Tribe holds an annual meet at Liberty Park.)

April 15th

More Blossoming

2:00 p.m. Several cultivar cherry trees blossom. They range in size from small bushes to two specimens with the first quarter-mile that are between twenty and thirty feet tall. In these larger trees, the gray birch-like pattern to their bark in addition to their bright white flowers are the keys to identification. More Box Elder shrubs have bloomed. One of the three horsechestnut trees at the Guardhouse gate parking lot have exploded, and each bud reveals a radial pattern of leaves surrounded by a cone-shaped green compound set of ovaries. Red ozier dogwood bushes that have leafed out have grown small compound blossom heads that look like heads broccoli. Chokeberries have resumed blooming and one near mile 0.2 is festooned with hanging flowerless blooms at the end of multiple heads at the end of long thin stems. Two immature rock squirrels betray themselves as their run over dry crackling leaves above the roadbank. A shadow across the road reveals to small hawks racing over the road. Their flight is so fast that identification is not possible, but front-wing line has a rounded shape. One seeking to increase its diving speed, folds its wing in to transform itself into a bullet shape. In an instant, they are gone around a ridge. Painted Lady butterflies are joined by a another cousin: a small dusky black butterfly that deep black triangular wing-tips with white spots. After yesterday’s warmth, the snow-melt fed stream today flows at it highest level.

The parking lot is overflowing with cars and their are sixty or seventy people along the road. The watercress gleaners have returned (October 16th) and they are carrying out bags of this edible that they removed from the seep below picnic site 6. I have changed my opinion on this practice: watercress is an invasive that chokes the stream, and if it is overharvested to the extinction, the stream may improve for native fish.

As I jog up-canyon, two young men bicycle down-canyon. They are wearing packs with hi-tech two-part snowboards strapped to the back in a triangle formation. They have ridden to the end of road and then hiked up to Grandview Peak for spring skiing. I did a similar 17 mile road trip ski tour and hike in the 1980s, and it is heartening to see the next generation of young men who would test themselves not in the arena of commerce or in sports against other men, but against the power of the nature. I give the trailing rider a big thumbs up, acknowledging what they have done. But he sees not as a kindred spirit, but only an old man on the lower road to which he gives no return glance.

On April 15th, 1909, a brush fire broke out at four miles above Eagle Gate in City Creek Canyon (Deseret Evening News). On April 15, 1906, boxer Young Corbett trained in City Creek (Salt Lake Herald). This was probably Young Corbett II, who later became the world Featherweight boxing champion. On April 15, 1898, the Utah Forestry Association planned to assist in planting trees in City Creek Canyon (Salt Lake Herald). On April 15, 1896, negotiations between the City and the Salt Lake and Ogden Gas and Electric Light Company broke down, prompting the City to further consider constructing an electric power station in City Creek Canyon (Salt Lake Tribune).

September 24th

Recovery

4:00 p.m. In the afternoon, the storm moves on, the clouds become broken, the air warms, and where the broken clouds create windows, beams of sunlight illuminates individual trees into beacons of color. Which part of the canyon and which tree is featured changes constantly. After an hour, the broken clouds end, the sky clears, and the canyon is bathed in the soft sunlight of Fall. The The ground dwelling crickets seem unaffected by the storm, but only the hardiest individuals of each type of flying insect is out, and this makes it a day of ones. I see exactly one of the entire cast of flying insect characters that are common to the canyon: one gnat, one dragonfly, one red-rumped central bumble bee, one white cabbage butterfly, and one jet black wasp with yellow-tipped tail. Five hundred feet above, a lone raptor that is to far to away to identify soars. As a finish my jog, the lowest part of the canyon is much warmer, and more gnats have returned. It will take a few days of warm weather for the flying insects to fully recover.

Because of the fall colors and because the canyon will be closed to public automobile traffic for six months in another week, city residents have turned out for automobile touring. I stop counting after the fiftieth car has passed. This annual automobile closure restricts the canyon only to pedestrians, bicyclists, and an occasional hunter, and during its winter sleep, the closure allows the canyon to recover.

Dragonfly Feast

5 p.m. The Sun is lower in the sky at 5 p.m. and is less fierce as compared to the summer solstice over 45 days ago. At mile 0.3 at a bend in the road, the group of about 15 dragonflies are doing dramatic acrobatic maneuvers. They’re doing rapid right angle turns, barrel rolls, and inverted loops. Because they are back lit against the low Sun on the western ridge, the cause of their gyrations is also visible. The air is filled with small gnats. Each gnat is barely one fiftieth the size of a dragonfly and if not back lit, they would be invisible. The wild flight of the dragonflies are attempts to catch the gnats in flight. The dragonflies wait for the gnats to fly up towards the Sun and then streak in from behind or below. At the last second the dragonflies flip over and try to catch their prey. Presumably, the dragonflies are waiting for the gnats to be blinded by the Sun as they fly upwards. But the physics of the matter is against the dragonflies. Being so much smaller and lighter, the gnats can make instantaneous right angle turns that the dragonflies cannot match. Being much smaller, the distance between the brain and muscles of the gnats is so much less that their reaction time is much faster than the dragonflies’. As a result, the dragonflies are rarely successful. I follow one dragonfly who manages to catch a meal on its sixth attempt. When I run past this spot again on my way out of the canyon, it is in complete shade, but now the swarm of dragonflies has grown to about 50 individuals. High above, a hawk circles.

Surfing Hawk

4 p.m. I reach the 1.5 milepost sign where the canyon first opens up. A summer storm front has moved in and there is a stiff breeze blowing up canyon. About a hundred and fifty feet up, but too far away to identify, a hawk is surfing the wind. He or she is flying a wide circle, perhaps three quarters of a mile in circumference, by making only subtle changes in its trim feathers. I watch for about 4 or 5 minutes, transfixed, and during this time, it only flaps its wings two or three times. Angling its wings to the wind to form a sail, the hawk gains altitude quickly. As it is about to disappear over the ridge line, a bicyclist whizzes by loudly playing, on a digital device affixed to their machine, a news report about another attention-getting statement by one of our presidential candidates, this being an election year. The broadcast breaks my meditative hawk-watching state and brings me back into my daily life of those things that my friends tell me should really matter. I am glad to have a refuge like the canyon a few minutes from home where such things are, temporarily, trivial and unimportant.
