Pearson - 1996 10 14 November - Night clear, spectacular stars. No dew or frost. Picked up the traps at 8 a.m.; not touched. There are many viscaccia droppiings in places, Phyllotis droppings, and Euneomys droppings. Some Ephedra near the crevice. Picked up 4 owl pellets at the crevice, plus some scraps of other mice. The presence of Euneomys pellets up on shelves in the crevices and nearby makes me wonder if Euneomys eating Ephedra might be the beast that formed the amber, rather than Phyllotis. Euneomys was abundant during the time the amber was being deposited in those other caves for which we have dates. Home for lunch. Joined by Eileen, John, and their two girl helpers from Enrique Lessa's lab in Uruguay. They are radio- tracking about 10 sociabilis. The pellet material from the amber crevice contained: 4 Oligoryzomys, 3 Auliscomys, 1 Akodon xanthorhinus, 4 Akodon longipilis, 3 Reithrodon, and 1 unknown. No Euneomys. Patricia Fierro came at teatime, then Christie came by at 8:30 to return a trap he had found today out at Los Juncos. He visited the region with Liz Barnosky. They saw a pair of barn owls at the rock outcrop. They want to go caving up under the big condor cliff. He saw a few condors. Temp last 24 hours 48-69. 15 November - Bariloche. Clear; overnight minimum 50. 16 November - Bariloche. Clear, warm. Drove out to the Hipodromo, then took the old dirt road to the west that ends up at Lago Trebol. Goes through wild country, much of it with no houses, good for trapping. When we came to the end of the road at Lago Trebol, a road race was on and we were stuck for about an hour while 50 snarling Fiats and Renaults, etc. screeched past, spaced a few minutes apart. Then headed home on the road past Colonia Suiza. We actually drove through downtown Colonia Suiza, but nothing there. Then ran into anotheer roadblock because of another segment of the road-race, so had to return to Bariloche via the Lake front. Nice grove of old pines, Monterey? cypresses, etc near where the back road emerges at Lago Trebol. Clara Bosch's brother lives there. Then drove out to Laguna Los Juncos and stopped at Marful's two houses, but gate locked at both of
