Crenulated Trees

4:30 p.m. Another storm refreshes the snow. While jogging up-canyon, I notice the various depths of creases in the barks of trees, particularly in mountain cottonwood trees. When young, their bark is almost smooth. The depth of the crenulations in cottonwoods’ bark increase with age, until near mile 1.0, an aged cottonwood has creases that are almost two inches in depth.

In Thoreau’s “Journal” on January 25th, 1852, he describes a frozen cattail. The sight of the sun reflecting off of the bottom of a stream reminds him of summer. On January 25, 1856, a collected pine cone opens are being warmed in Thoreau’s home. He marvels at the difficulty of and the ability of squirrels to remove seeds from a closed cone. On January 25, 1858, Thoreau notes the many types of buds on trees.

On January 25th, 1925, forty-one students of the University Hiking Club, went up Black Mountain, slid down the mountain’s backside, and hiked out City Creek (Utah Daily Chronicle, Jan. 30th, 1925).
