Hoffmeister 1942 Itinerary June 10 Waucoba Pass, Inyo Co., Calif. creek, is about halfway between Oak Creek, in which we saw "live" oaks and Big Pine Creek, in which we saw no "live" oaks (=oaks that don't lose their leaves in the winter). Along Birch Creek there was a dense thicket of willows at about the 4500 foot-level. We did not investigate the thickets closely, so I do not know if there were any Neotoma fuscipes houses. In driving down from our camp along Big Pine creek I saw several (15') Citellus beecheyi. They occupied as far up as approximately the 6500 ft. level. Returned to Big Pine, and drove via Juricks, up the Waucoba Pass Road into the Inyo Mountains. One strikes the piñon-juniper belt at roughly the 5500'ft. level, but here they are very sparse. Continued down and out of Marble Canyon and on to the summit of the pass which leads down into Saline Valley. This is approximately east of Waucoba Mountain. Our elevation, 7300 feet, is taken from the barometer. We are lodged in the cabin of a Mr. Cressfield of Big Pine. The slopes and gullies are covered with piñon- juniper (about 1/2 piñon; 1/2 juniper). There are flats scattered irregularly throughout this area, and these flats are filled or grown with Artemisia, Chrysothamnus, Lupinus, some Loa and
