Mayhew 1960 Apr. 11 Journal 22. Mojave Desert, San Bernardino Co., Calif. Frank Aubrey, Walter Mobley + I left UCR at 1015 on our monthly collecting trip. The weather was beautiful when we left, but as we approached Yucca Valley, we could see a good sized [illegible] cloud bank in the east. By the time we reached our collecting site at Dale Dry Lake, the sky was completely overcast, and the weather was quite cool for this time of year. We arrived at Dale Dry Lake at 1345. We began to look for lizards, in spite of the weather, at 1355, and continued to look until 1525. During that time the maximum air temp. was 25.8°C. We saw a total of 5 Uma scoparia (all adults). We caught 2 of these (1♂; 1♀). We saw + caught 1 Urosaurus graciosa [adult] + 1 Chimactis occipitalis (imm.). No other reptiles were seen. It appeared the coolness produced by the overcast, and the S.W. wind (9-12 mph), tended to keep the animals inactive. at 1530 we drove east toward Rice to see if we could get out of the wind behind the hills. In spite of our efforts, we were unable to escape the wind. Not one vertebrate (alive) was seen before we reached the Riverside - San Bernardino county drive. However, 2 Masticophis flagellum + 1 Phyllorhynchus decurtatus were found DOR. We stopped at the county line to cool
