Pearson-1992 2 mostly cloudy and windy. Drove up Cerro Otto to Piedras Blancas and visited our two bamboo clumps. About same. Clump A1 out in the open had two surviving shoots about 2m tall; a little snow in the middle of the clump. A few other patches of snow on the slope, but not as much as last year (when we were a week or more earlier). Lenga leaves were wellout on some of the trees. Lots of earth cores from tucos and/or Chelemys, plus heaps of loose earth up to 10 gallons in volume, not at all weathered, some of them in fairly forested spots where unlikely to be tucos. Finished doing the pellets collected by Patricia Fierro on October 25 at Rayhuao, 25km S Pilcaniyeu =halfway between Pilcaniyeu and Las Bayas. Pellets were under mixed conifer and hardwood trees around the ranchouse; from the size they were Bubo: Ako. xantho. 12 (o,?,ygad,ygad,?,ad,o,ad,ad,ad,ad Euneo. chinch. 9 (o,ad,o,ad,ad,ad,ad,o,ad Reithro. 5 (ad,ad,ad,ad,ad) Ctenomys 2 (both small) Eligmo. 2 (ad,ad) Aulisco. 1 (ad) Abro. longipilis 1 (ad) Bird 1 Insect 1 (large chestnut sheets of chitin) Went to Patricia Fierro's and Jorge Vallerini for dinner. Very windy/rainy/snowy. Raw. Signs blown down. Jorge says lots of rocks at Rayhuao where the pellets with Euneomys came from. About a half-inch of wet snow and wind while we were there. October 29- Bariloche. Morning cold (38), clear, windy. Ice on the sidewalks in shady places. Cars from the suburbs had more than 3 inches of snow on their roofs. Since we have been here this trip, the pressure has risen gradually 500 ft. Gave two Euneomys skulls to Parques. About 4 pm put traps out for Akodon xanthorhinus on the road to the airport. Dramatic difference in snow cover between the turnoff from the lakeshore highway (no snow) to the airport (about 2 inches). I put 29 Shermans baited with rolled oats and Anita put 29 baited with rolled oats and cornmeal; bunchgrass, rosa mosqueta, Colletia, Acaena, Berberis. Cold and windy, partly cloudy. After dinner Maria Elena D'Angelcola, Salta 587 1A, came calling. She is from Univ. Buenos Aires and is looking for field experience. Had done some work with fishes. November 30- Temperature at apartment 40°F, airport 2°C and 40km wind;. Still some snow out near the airport. Ran our traps at 8:30, sunny, windy. My line had 4 Abro. longipilis, 3 Auliscomys, 1 Oryzomys, 1 Reithrodon; all
