P. PEARSON 1951 5 Dec 3 Temperature on the beach when returning yesterday at 10 a.m. 73°, humidity 73°. This morning at 6 a.m. temp. 60°, humidity 80°. Nothing in traps but some footprints near one of Anita's. Dec 4 Much driving over much bumpy road and some photography of the Loma and baremore. Slept on long upgrade approaching arequipa. Dec 5 Most of day in Arequipa, then back up the hills to the SW. Camped near the crest of these hills at 8500 ft. Stony sandy hills with scattered dried shrubs and tall cactus (pipes 2" drain). Had just parked bus when spotted herd of guanaco's only 300 yards away. Collected one with Horvat. Skinned it, then set 35 Museum specials down a sandy wash and along a stone wall (remains of mining activities). Anita set 25. Served fillet for supper. Temp: + Dayt: +46° Dec 6 Skinned mice (2 Phyllotis in my line and 2 in Anita's) and finished guanaco. Both my mice along a stone wall, none out in desert under shrubs. One of Anita's along stone wall, other under pipe cactus. Then drove to about 20 km. W of Moquegua. Some mice barcaver on the Molle-do road, and several mice stretches of loma vegetation. More of the rusty orange "rootless" deben. Numerous flies + beetles among the low flower meadows. The orange deben is found on the inland fringe of the Loma. The wild "Penstemon" frequently seen out on the gravelly desert is also almost rootless, hence unattached. It can be dislodged with a nudge. Camped in a dry wash about 20 km. W of Moquegua. Scattered shrubs in the wash and a few feather-leaved trees.
