Peterson 1935. Nine rat traps set amongst rocks of cliffs of Road Creek Canyon + 4 mouse traps amongst buildings adjacent to camp grounds. Also one steel trap set in burrow found beside a cliff on canyon slope. Evidence of former presence of wood rats found in form of old feces + nests, but present number of rats few due to distribution of poisoned grain some- time previous to our arrival. Deer startled out of semi-sprawling aspen while setting trap. Identification of deer impossible due to failing daylight. July 31. 13 mi. N Paradise Valley, 6700 ft. Humboldt Co., Nevada. Catch consisted of one Neotoma c. cinerea, one young Perognathus p. olivaceus (along fence of Range's residence), 4 Peromyscus + m. sonoriensis. Hike up side canyon to peak about 7500 ft. to south of camp site. One Callospermophilus lateralis and 4 Eutamias m. sculptor shot on slopes canyon + on peak. Cattle seen, manifested much alarm at sight of a muck-bearded human being. Skins prepared of the Neotoma c. cinerea, Callospermophilus lateralis and one Eutamias m. sculptor.
