Hoffmeister 1942 Itinerary May 15 4 mi. SW Olancho, 5200 ft., Inyo Co., Calif. Left Berkeley yesterday, May 14, in company with Ward C. Russell and Frank Alois Stelka at 6:15 a.m. in the Dodge truck. Drove via highway 99 through the San Joaquin Valley to Bakersfield. From here drove, via highway 178, up the Kern River Canyon. At 12 miles, by highway, out of Bakersfield, the Kern River is next. At this place, and for several miles along (up) the River, the habitat appears suitable for Peromyscus crinitus. It was in this general vicinity that Guttman (Biol. Survey) collected about 40 years ago, a P. crinitus. This is the farthest this species has ever been taken west of the crest of the Sierra Nevada. In the lower end of the Walker Basin, at Bodfish, there were junipers growing in the valleys and on the slopes, but no piñons. We continued on to 1 mi. E Isabella, where we camped for the night. Here, on the Doyle Ranch property, we collected Tricolor Blackbirds and Red-wings. These were along a creek grown with cattails & Sirpus predominately at this place. Tricolor Redwings were the most abundant, with nest building completed and egg laying finished in most instances. Collected a mud turtle, Clemmys marmorata, along this creek. I also heard a mouse run along a runway leading into a hole, and assume it was a Microtus californicus. Citellus beecheyi were observed along the highway only as far as 20+ mi. out of Bakersfield. Piñons were seen again only 1 mi. from the summit of Walker Pass in the Basin. Apparently the piñons rim the Basin, rather than occur in the bottom of it. Broke camp 1 mi. E Isabella at 8:30 a.m., May 15, and drove over Walker Summit to Freeman. Here we turned north and drove up Owens Valley
