P. PEARSON 1949 68 July 14 No trips spring. Home 10 a.m. July 22 Left 8:15 a.m. with Mary, Pitler, and Dr. Esteban for Napa Co. Comperthina. First to Knowville where we looked in 3 tunnels. One steep tunnel with "debris" over it, skipped shaft entered by ladder. I went down about 75 feet and never did see bottom, no bats. This one (3) was up on hill. No 1 (no data) was on hillside behind abandoned house, and No 2 (one awake & cory) was just along road to Lower Lake. (1) Dr. caretaker here mentioned more tunnels 4 miles up right fork of road (which later returns to lower lake road at Reiff) so we drove there, a location known as Reid Mine. The manager said no bats in the tunnels & crossed out near the headquarters but referred me to 3 further up the road. Two were a few hundred yards back an old road (blocked) to the right of the road about ¾ mi. N of the headquarters. (One of these was a good tunnel but no bats. The other was more than half full of very murky water, we didn't go into it). The other tunnel had a narrow opening at the left edge of the road about 1¼ mi. above the headquarters. In this tunnel, which had several short branches, we caught 2 active & cory and 2 torped & f. Thus all 308+ bats were awake, both ff torped. Home 7:15 p.m. via Argentin & Pope Valley.
