Weston 1946 Journal /8. July 6 Sand Dunes, Pinto Basin, elev. 1775 ft., 1 1/4 mi W + 2 3/4 mi S of Pinto Peak, Joshua Tree Natl Mon., Riverside Co. Calib. arrived at the center of the Basin at 6 p.m. There we parked the car at the edge of the road and headed for some sand dunes one mile +/- to the north. From 6 until 7 p.m. we were out on the dunes looking for reptiles and mammals. Several Callosaurus and Cnemidophorus were seen, the former out in the flat floor of the basin as well as on the dunes. One Uma was shot. At 7 p.m. we were back at the car and were eating dinner. Packing up some of our equipment (sleeping bags etc.) we hiked back out to the dunes to spend the night. After dark, we got to the dunes again at 9 p.m. We walked around with a Coleman lantern looking for vertebrate sign. On the soft sand we saw tracks of desert tortoise, ground snakes, one questionable track of a sidewinder, and mammal tracks, those recognized being Dipodomys, rabbit and coyote. Collecting was poor so we rolled out our sleeping bags and went to bed. Just before going to bed at 10:30 p.m. on the dunes, Wade and I set out some snap traps. He set out 30, I set out 25. The night was clear and no wind was blowing.
