J. G. Hall 1952 July 2 Sagehen Creek, 3 mi. NW Hobart Mills, Nevada Co., Calif. 2 PM. Started downstream from where highway 89 crosses. Visited the roadside colony for a while. This seems to be a well established colony with most of nearly aspen cut. Some sprouting from stumps, mostly of 3" diam. Counting nodes indicated sprout- ing started 1949. (:: cut fall of '48 ?). Good willow supply. A great deal more grass than found in other colonies. Some winter high-topping of aspen 6-7' from ground. Most aspen cut 15' or down to water. Some willow use. Although it covers a larger area than rockslide col- ony, first impression based on subjective measurements of willow use + aspen use is that this colony is intermediate in age between rockslide & highest. Several downed trees 6" only partially used, smaller branches trimmed & removed & bark eaten off main trunk in a couple of places. Large & small pines killed by drowning. About 5 small dams in series, about 20- 50 yds apart, lodge between 2nd & 3rd dams. Pond gets deep, about 5' in vicinity of lodge. Several 1" willow stumps show sprouting, mostly growing from 1951 on. Pewee & Sapsucker seen out around dead snags felled by
