Mayhew 1960 Journal 23. Apr. 11 Mojave Desert, San Bernardino Co., Calif. Dinner at 1720. While there we found a live adult Crotalus cerastes about 30 feet from the car. After eating, we began night collecting back toward Dale Dry Lake at 1830. All we found before we reached Dale at 1940 were 2 DOR Crotalus cerastes and 1 DOR Uma scoparia. We camped near Dale in our usual location at 1940, after driving 149 miles today. Minimum temp. tonight was 54° F. Maximum temp. today was 79° F. A S.W. wind, 10-15 mph (gusto to 23), blew all night, making our camp a rather unpleasant place. Apr. 12 I arose at 0605 because I was sick, sick, sick of sand in the face. The wind is still blowing as hard as ever, but the clouds have disappeared. The other 2 fellows didn't arise until 0720. after breakfast, we decided to leave the area + return later in the month. We left the region at 0845. 18 miles east of Dale Dry Lake we stopped to look for lizards in a rocky area near the road. Two Sauromalus obesus (a pair) were captured here. No other lizards were seen. We drove on to a lunch stop 9 miles north of Desert Center. At this stop we captured: Diposaurus derelicis-3 (2ad Ø; 1im Ø; 2 im ♀)
