Culbreath 1942 S. Fork Mt. 4 mi N. Mad River Rock. El, 3,100 Trinity Co., Calif. Jan 17 When one yellow legged frog was collected. Working up the grassy slope not found a pure isolated group of 12 large Western Red Cedars. The Golden Crown Kinglets and Mountain Chickadees were feeding in their tops. Just before reaching the top of the ridge the grassland breaks into a border of Western Red Cedar Trees that are about 10-16 feet tall this runs into brush principally manzanita and directly on top is a good stand of Douglas Fir and White Fir. A road runs along the ridge of the mountain. Car travel is prohibitis at this time of year by snow. Large patches of snow were covering the road in places 8 to 12 inches deep. I worked along this road to the 5000 foot elevation and then dropped down the ridge to the west. A good cold wind was blowing along the ridge and most of the birds were on the west facing slope where they ever protected. The ridge that I came down was almost pure Western Red Cedar, down to 4000 foot level, where it merged into the Douglas Fir. The only birds observed in this cover were large bands of Juncos and small groups of quail and small groups of Kinglets and Chickadees.
