Journal 23 Myrmal Reig 1969 July 8 2 mi. N Casapalca, 14,400 ft., Dep'ts Lima, Peru 6:00am We checked our traps. I caught nothing in my 39 Shermans. Carl caught 1 Phylotis [illegible] andium in the same type of habitat as I trapped in. Dr. Pearson caught 7 mice in a rockier place than mine, with the same lupins & Senecio. He caught 2 Colomys sorellers, 43 Phyllotis andium, +1 Phylletis darwini posticalis. Ray trapped at higher elevation where we are camped (>14000). In rocky bunch-grass, he caught 1 dead Phylletis darwini posticalis, 1 Creomys feldskii, 2 Calomys ducilla, and 2 Colomys sorellers. Apparently then, Pearson, Carl and I were trapping in the range overlap of Phyllotis darwini posticalis and Phylletis andium, while Ray was trapping in pure P. darwini posticalis territory. Last night it was well below 0°C, and a wind was blowing. This morning it was -4°C, and so abundance of frost on the ground indicates moisture. Where we trapped at [13,300] ft., it was less windy and warmer. The slopes are steeper with less grass and more chaparral. The locality line is 2 mi. N Casapalca, 14,400 ft. We will take chremes from 10 of the live mice [illegible] today. 4:30 pm. OPP, Ray, + I set about 35 small Sherman + 30 large folding Shermans about 100 ft. up the road from where we trapped last night. Dr. Pearson set his folding Shermans along rock walls + bunch grass on the north-facing slope (as was last night's slope). Ray turned
