Culbuth 1942. Jan 24 S. Fork Mt., 4 mi N. Mad River Rock, El 3100 Trinity Co, Calif Little collecting was done today due to heavy rains and winds. One woodrat was caught in a steel set for a cottontail under an old junk pile. One Peromyscus maniculatus and one true fox were caught in manzanita corn, and two Microtus were taken in the shot grass under logs at the edge of a young glade. One Chithionomy was caught under down logs under a Douglas fir corn. Jan 25 This AM. Ward and I drove to the ridges of South Fork Mountain on highway 36. One flycatcher, one golden-crowned kinglet and one chukades were collected at a point 1 1/2 miles north and 2 miles east of Mad River Rock. It was raining lightly but the wind was very strong all along the ridge. At times the clouds formed fog right to the ground. The ridge is covered at the above point with scattered stands of scrub, California black oak and Douglas Fir in pure stands. Small open glades intersperse the tree covered slopes. Manzanita is found but its forms only limited corn. Evidently the manzanita plants
