686 Horse Ridge, at 5500 ft., SE Ruth, Trinity Co., Calif. May 28, 1933 Gilmoe 1933 and Yellow Pine seem to be the dominating Trees and are of huge size. Form about 500 ft. approx. 500 ft. there is a stand of White Pine in the bottom of the canyon which by now has become somewhat dry and precipitous, 75°. The Firs & Douglas Spruce at the head of the canyon do not represent good Canadian zone territory for Nestoma fusiceps & Eutermas bogomae were taken there. However, Fox Sparrows and Green Tailed Tanagers in small numbers seemed to be Nearby breeding nearby. There appears to be no good Canadian zone areas on the West side of Horse Ridge, despite the patched Canadian brush and trees. Probably on the east side of the ridge, where David now lies heavily, there is better Canadian Zone spots. From about 4000 down to the valley floor of the Mad River, the canyon mentioned above seems to be like many of the surrounding ridges, dry with scattered Yellow Pine, Douglas Spruce and Black Oak.
