The top of the ridge was park-like yellow pine forest with understory of Ceanothus (Cordu- latus?), scrub oak, and seedling yellow pines. Took 2 Fox Sparrows, a mountain chickadee, and a pygmy owl along the ridge top. Heard numerous Cassin finches singing in the tree-tops. On the way down collected an Oregon Junco by a shaded creek. The bird was one of a fair that came to my owl calls. Skinned in P.M. May 31, 1946 Trap lines yielded 1 Microtus californicus. Went east of camp about 1 1/2 miles and then left the road and cut up to the top of the ridge. The top of the ridge was very rocky with large, dense patches of manzanita and Ceanothus growing between the rocky outcroppings.

Hiked along the crest and then worked down through the yellow pine - Douglas Fir forest back to the road, taking Three Fox Sparrows, a mountain chickadee, an Audubon Warbler,
