City Creek Nature Notes – Salt Lake City

April 30th

Butterfly recovery

3:00 p.m. It is overcast but warm in another weekend day, the parking is overflowing and there are over one-hundred persons on the first-mile of road. Hiking down the road is a bearded hunter-type wearing camouflage fatigues and strapped to his backpack at two whitened deer antlers. He has been collecting, motivated that a market that can bring one-hundred dollars for their best high-point discards. But more usually, the price four dollars for average samples. The first young one-foot tall cattails reappear at the seep below picnic site 6. Last year’s grove is rebuilding (October 25th). A mallard is resting in the flood retention pond, unperturbed by four anglers casting around it. In the first mile, I hear eight unseen chickadees in the thickets. The call of an unseen hummingbird is heard.

Butterflies are recovering from the cold weather, and I glimpse five types of small butterfly with a wingspan of less than one and one-half inches that is feeding near a red-rumped worker bumble bee. They are fast and this makes identification difficult. One is a dusky orange with small black wing spots and a black thorax, perhaps a Zerene fritillary. Another is a uniform light blue. The third is light blue with widely-spaced blue-veins on its wings, probably a Western blue-tailed (Evere amyntula). The fourth is the same, but the veins are closely-spaced, possibly a Spring Azure (Celastrina ladonecho). The fifth has the same molted brown pattern as the light-decomposing leaf layer on the ground. I notice it because a small black ant is dragging one of the wings away, that is twelve times its size, back to its nest. That the ant has chosen this prize illustrates the importance of protein to the ant colony’s development.

On April 30th, 2006, the City continues to develop its proposal to create a 1.5 mile above ground greenway that would receive City Creek’s flow and “daylight” channel the creek above-ground from 45 South 700 West to the Jordan River (Salt Lake Tribune). On April 30, 2005, a Primary Children’s Hospital Patient ties a “wish note” on a tree to be planted in City Creek Canyon (Deseret News). On April 30th, 1996, the Salt Lake Tribune rates the Bonneville Shoreline Trail to City Creek Canyon the third best mountain bike ride in Utah. On April 30th, 1943, all travel into City Creek Canyon and north of Thirteenth Avenue was banned due to drought and extreme fire hazard (Salt Lake Telegram). On April 30th, 1899, the Social Wheel Club planned a bicycle outing up City Creek Canyon (Salt Lake Herald). Club plans for a 100-mile ride in June are discussed.
