K Pearson 1950 December 16, 1950 Clear Lake, Lake Co., Calif. Left about noon with brats. Arrived at Sulphur Bank house about 3 PM + found there one Coy on a raft in basement room. I marked the spot where she hung and left her undisturbed. Proceeded to the tunnels at Lucerne. Both empty. The north tunnel has recently had either a fire or an explosion in it. There is fine black dust on ceilings & walls of the entire right branch of that tunnel. A terrible smell - south tunnel was drippy back in the right fork as well as near the entrance where the floor had visible puddles. The north tunnel was mainly drippy near the cave in far way back. Checked tunnels at 9 PM - no brats. AM temp outside = 45°; in north tunnel it was 52° about 15 feet in from mouth. We went back to the Sulphur Bank house and found our female unmoved since yesterday. Temperature near this bat was 79°. Came home through Acton Spring + picked up one headed ♀ (gray vagina) for some open survival experiments. Dec. 20-21, 1950 Markella Mines, 2000 ft., Napa Co., Calif. Left at about noon with Bledel & Paynie, heading first for Acton Spring. Litter attic 50°
