Mayhew 1960 Journal 19. Mar. 21 Mojave Desert, San Bernardino Co., Calif. We reached UCR at 2040, after driving 227 miles today. We drove a total of 991 miles on the entire trip. Mar. 28 Deep Canyon area, Riverside Co., Calif. Walter Moberly, Frank Aubrey & I left UCR at 0910 in the '52 Chev. camry-all (1223) for the Coachella Valley. I had seen 4 Diposaurus israelis active on March 24th, so we were trying to get some. There were strong winds blowing on the desert today, however, so not many animals were active. One adult Diposaurus dorsalis was seen all day (we caught it). The first Crotaphytus wrighti we've seen this year was captured today. We returned to UCR at 1540, after driving 143 miles today. April 2 Mojave Desert, San Bernardino Co., Calif. Frank Aubrey & I left UCR at 0720 with 25 Field Zoology students. We reached the Mojave River, 3 miles north of Cedar Springs at 0830. Spring apparently has not arrived in this region yet. Few leaves are to be seen on any deciduous tree. Very few birds were seen during our stay. The wind was rather strong, which may have partly explained the rather small number of birds seen or heard.
