and the other a little alone, about 2 Sherman in brushy rocky places along river, night clear. July 29 Clouded up during night. My traps caught 1 P. darwini, alcedon bolivensis, and colomys spp x Total 8. Between Challuana and Purquico, saw only two herds of vicunas (both together and united with grazing alpacas and llamas). Between Purquico and Uzoa there were numerous herds near the "Vicuna Refugio" (July 30). Camped among huge rocks, toda, grass etc at 2 miles east of Purquico and about 1000 ft above it. A few hundred yards below our camp there is an abrupt change to large bunches of various kinds, spiny or red-tubular flowered etc, very similar to my memory of Phyllostis megister habitat near Tarata. Pest out about 24 Sherman in good brushy-rocky habitat, and 15 ± centrap in more open rocky- sav places. Night clear. July 30 Barely frosty. My traps held 1 colomys soroline?!, 1 alodon bolivensis, and 1 Phyllostis darwini? - Andy and Dymon caught Colomys and Phyllostis older. Some of the Phyllostis are huge, but look more like darwini than megister. Patagona gigas is here. I don't recall anywhere where altiplano changes so abruptly to brush as here - within a few hundred yards. [illegible] Interminable switchbacks and rocky road from Purquico to a desert camp between Uzoa & La. Losing oil through night near grease seal.
