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.

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.
