Jan. 28 Dale Dry Lake area, San Bernardino Co., Calif.
This morning at 0845 Frank Aubrey,
Fritz Zabel, Mark Kuhn & I left UCR.
Just north of San Bernardino we
discovered Mark's sleeping bag had blown
off the car rack we were using.
We retraced our steps without finding
it, so I picked up an extra one at
home. We finally got underway at
1000. We drove through Hesperia, Lucine
Valley to Old Woman Springs. Two lite
stevansiana were seen at 1300 in the
sun at this location. At the time,
the wind was 7-15 mph from the S.E.; the
air temp. at 30" was 16.5°C; at 1cm. it
was 18.0°C.; soil surface temp. was 26.0°C.,
relative humidity was 37%. One was
setting on the windward side of a rock
pile in the sun. We found a fine
Joshua Tree woodland near Giant Rock.
It should be quite good for Sceloporus
magister. It is 11 miles north of
the junction of Old Woman Springs Road
and 29 Palms Road (between Joshua Tree
and Yucca Valley). We reached Dale Dry
Lake at 1620, then climbed one of the low
hills to the S.E. No Uma scoparia tracks
(or any other reptile tracks) could be found,
although numerous bird & mammal tracks)
were visible. It appears that all the
reptiles are currently hibernating here.
