1973 5 mi. N.W. Westgard Pass, 4100'; Inyo Co., Calif. June 27 We returned to our camp at Grandview and drove to Big Pine for gas. At about 7:00 pm we returned to Deep Spring Valley to set our traps. Set 13 traps near 4390 marker of hwy 169, about 10 mi. from Westgard Pass by Rocks. Soil quite sandy, with ATRIplex present, Thurg not dominant. The saltbush was a different species than that of the Owens Valley having winged bracts (drawing). Arrived about 1/2 hr after sunup to collect traps. Results: 7 Dipodomys ordii; 5 Perognathus sp (probably longimembris). No microps here. We decided to go to another locality to trap for the second night's trapping. We left about 10:30 AM for Mowamba Cyn, Inyo Co., from which the highest known specimen of D. microps have been taken (7700 ft.). The road leads east out of Independence and is paved the first 5 mi or so. Thereafter, it is dirt. At about 5500 ft. the road forks; I assumed the right fork to be the one I wanted to take, but the crown was too high for our car, and rocks prevented driving straddling the crown. The car also overheated at this point, so we turned back to go to an alternate locality, 5 mi. N. Benton Station.
