Leaf Variation

2:30 p.m. I notice at various points along the first mile that the brown Gambel’s oak leaves by the side of the road are not uniform. Below picnic site 5, they are the rounded-lobe shape that I have come to define as “Gambel’s”. But below picnic site 7, there are Gambel’s oaks leaves that have lobed leaves on the bottom half and serrated leaves on the top. To make sure that I have not erroneously identified these leaves, I make a note to revisit these locations after the trees finish leafing out near the end of spring. It is overcast today, and without the sun, there are no stoneflies on the road. With the warmer temperatures, the flock of Black-capped chickadees at picnic site 3 have moved up canyon below picnic site 5. At home in the valley, I spot a flock of the chickadees’ cousin – Oregon juncos.

In Thoreau’s “Journal” on February 17th, 1854, he observes mice tracks in the snow.

On February 17th, 1907, City Engineer Kesley presented a report reviewing accomplishments on infrastructure improvements over the last several years, including the laying of 113 miles of paved roads, 100 miles of sidewalks, 40 miles of sewer lines, and 12 miles of water distribution lines (Intermountain Republican). Among his proposals to increase the City’s water supply was the construction of a 5,000,000 gallon reservoir at Pleasant Valley in City Creek Canyon and replacing a wooden flume with a concrete flume near the Brick Tanks reservoir in the lower canyon (id, Salt Lake Telegram, Feb. 18th, 1907).
