On the way home between Montreello and
Mojave saw several dozen [illegible] woodpeckers
along one stretch of road a mile or two long.
Skidoo, 5700 ft, Inyo Co., Calif.
Jan. 1. Looked in one tunnel along the road at Skidoo. It
was a long cold, slightly drafty tunnel. Found
one torpid & Corynorhinus while driving up out of
Jan. 2 Death Valley at 6 p.m. saw many moths flying, temp.
[illegible] measured outside car window was 47°
Camped just north of Lone Pine at about 9 p.m.
Very windy, temp. in low 40s. In middle of
night (dark) temp. was 35° fell at dawn 20°
at dawn saw a single bat flying from the valley
toward the western foothills. When it became lighter
we saw 2 tunnels in the hills about where the
bat was heading. They were warm 58°, with
many owlets; found no bats in them but could
foresee many in the crooks.
Subway Cave, Inyo Co., Calif.
Jan. 20 Left 1 p.m. with auto. Arrived Subway 8-½ p.m.
According to Parrish the autumn has been very mild;
later night one of the few cold nights of the year. Looked
in Subway Cave briefly. Not many ticks or ice stalagmites. No
bats in north branch, which was rather dripping; the sleeping
glacier much too wet for sleeping of south branch. More flying
Jan. 21 Looked in Subway again; nothing in north branch; quite
a few in south. Only 1 in the usual hibernation chamber (37°)
all its rest on high ceiling of cross road (temp 32°). All torpid.
