Pearson - 1993 15 were in nire forest/scrub also, with lots of berberis clumps and cow trails. My line 21 Shermans and 21 Museum Specials alternating, then 15 more MS. Peg's line:30 Shermans and 30 MS, not alternating. Anita's line: 28 Shermans and 28 MS set in pairs. Peg and Anita checked much of their lines before dark, but nothing. 29 November- Cold rains and drizzle most of the night, and even snow/drizzle in the morning. Large puddles in the road, along the road, and at places in the forest. Picked up traps about 7:30 a.m. I had 1 Ako longi and 1 Auliscomys, both in Shermans. Many MS sprung by the rain. Peg had 4 mice in Shermans ( 1 Geoxus, 1 Ako olivaceus, 1 Ako longi, and 1 Auliscomys) and 3 in MS (2 Ako longi and 1 Ako olivaceus). Anita had 5 mice (in Shermans 1 Geoxus and 1 Auliscomys, and in MS 2 Ako longi and 1 Ako olivaceus). Skinned until noon, then got hopelessly stuck on the way out the road. With the help of the whole Chihuay family, a horse, three other helpers, and finally the Chihuay jeep, we got out. They accepted no payment. Weather cloudy. Then drove back to the west end of Lago Mascardi and camped back the road to a quarry, about 100 m from the Rio Manso Superior. This is perhaps 1/2 km west of Sigfrido's cabin and the Campimento Educativo. Lots of small fields of green grass and clover, much grazed. The habitat is nire forest opened up for grazing. Lots of patches of enormous Berberis calafate up to 10 feet tall and stems >2 inches in diameter,lots of retamo on Peg's and Anita's lines, lots of grazed clumps of bamboo, some rosa on Peg's and Anita's lines, bigpatches of lupine on my line near the river, all interlaced with cow trails. I put out 27 Shermans and 27 MS, alternating, near the river in old nire forest with bambo and Berberis, patches of lupine, grazed. Peg put ut 25 Shermans and 30 MS paired. Anita put out 28 Shermans and 28 MS paired. They checked part of ther lines before dark; nothing. 30 November- Drizzle and snow overnight, about 1/2 inch on car and bushes. Overcast. Picked up traps at 7 a.m. My line had 1 Ako longi and 1 olivaceus (in live traps). Peg had 1 Oryzomys and 2 olivaceus. Anita had 5 Ako olivaceus. So, all the olivaceus were nocturnal, and most squeaked when handled. Day mostly overcast. Drove to the cirque at the end of the road. Many big trees down along the road. Never did see the top of Tronador. Then home; drizzle or rain all the way.
