P. PEARSON 1955 The south facing slope here is all bunch grass, no lupine. Among the lupines are some shrubby, desiccated leafed yellow-flowered ?sericea??. Looks more like andinum terrini than darmini, much warmer here than at the 14,000 ft. camp. Cultivation on both N and S slopes; very steep. Also put traps at 1 mi. W Casopolca, 13,300ft. on a south- facing slope growing to rich, the desiccated leaf yellow-flowered ?sericea?, and lesser grasses + forbs. The upper part of the line had some Baccharis (a couple of 5-foot-high bushes, fleshy sericea, and also a woody thorny shrub with red Indigo paint brush flowers. I think some as above Tarata Schquisen or Chiquiguan, or something like that. Enough iden so that ozole could live here. The upper of these two trap lines is where a mine aqueduct carrying sludge crosses the valley by suspension bridge and the lower line is just below where this sludge is dumped into a side canyon. Aug. 15 Might clear, ice at 13,300ft. The upper trapline (1mi. W Caspolca, 13,300 ft., rich) caught only 4 Hesperomyz and 1 phi darmini postrealis. The lower trapline (1 1/2 mi. W caspolca, 13,200ft, 13,200ft, lupine) caught ?7 andinum, 5 postrealis, 2 Hesperomyz, and 1 abdon jdsalcai. Andinum and postrealis were in adjacent traps, but in general the postrealis more open, the andinum more bushy. Drove over the pass to Orroya, then north toward Cerro de Pasco. The pass, about 16,000 ft, is smoothly bare.
