RBC2. Had 17 small Sheevens out all day, but caught nothing. Saw a q Orestachillus standing on the ground at Volstrichs house. Seal singles, but heard no trumpets. Quite sterile area. We go along a stream at 13,900 ft. between Zogs Sickle and Zogs Sorasta. April 5 night overcast, clearing toward morning. Frost on windshield but not on car. Morning partly cloudy, afternoon cloudy. Drove about 10 miles, then discovered from roadscreaper that we were on the Condarine Road, so turned around and headed for Santa Rosa. Turned back to Caeserchala road just over the divide from Santa Rosa and drove back to our old Viscacha camp, food just as awful as ever. The Caeserchala Valley was full of alpacas and sheep. Hundreds of them, and a thatched hut x Decided not to stay there, so drove back almost to the turn off the main road and camped in a nice empty Valley. About 5 min E of Zogs Sorasta, 15,250 ft. Put out about 65 large + small Sherman baited with rolled coto, along stone walls. Saw anising Bolivian. Saw one band of Vicunas between here and Caeserchala: one male with a band of 10 that included at least 2 young. Started to snow - fell just before dark, and offed on all night. Full moon was bright through the clouds, so the mice had snow and moonlight. Ran part of trophy in 1 AM, but nothing. Warm + still.
