Pearson - 1994 8 Then drove south, part of the road great but about an hour of detour through thick dust. Saw 5 crested tinamous. Camped in mixed Larrea about 10 km south of El Sosneado. Saw one hare at campsite. November 15- Drove up the valley to Las Lenas. Lots of goats below the ski resort. The road was blocked by snow at 6 km above the main ski lodge, at about the same point where it was blocked at our last visit several years ago. Most of the habitat is dry rocky slopes with thorn bushes (Mulinum, Berberis, Azorella, yellowbark bushes with heavy spines, brownbark bushes with slender spines, Ephedra. Hare droppings. A few seeps have big clumps of a very spiny bunchgrass plus big heads of Azorella and some ?Distichia?. About midday I set 7 steel traps, 18 Shermans, and 4 Museum Specials, mostly in indistinct runways between the big green bunchgrass, hoping for Euneomys mordax. Saw no droppings or other sign, but about three burrow openings. Anita set 28 Shermans, 26 Museum Specials, and 3 steel jump traps, all on dry stoney hillside. She saw some pale, coarse, rice crispie Euneomys droppings, about the right size for E. chinchilloides. Later in the afternoon (4:30) we found a seep with big Azorella heads amid the spiny bunchgrass and with fresh-looking holes under the yareta and with big Euneomys-style droppings; even an "earth" core made up entirely of dead stems of yareta, apparently hollowed out of the inside of a big head of yareta and pushed into a runway in the snow. One big head of yareta had a mouse hole chewed through the top of the dome. We set 3 steel traps and 6 Museum Specials. I forgot that we had some cage traps in the car. Ran my traps at 6 p.m.: 1 lizard, 2 Abrothrix longipilis under scrub bushes. Anita had 1 lizard, 1 Auliscomys, and 1 Abrothrix. November 16- Night cold but not freezing. My traps in the morning had a male and a female Abrothrix longipilis, a male Auliscomys, and a male Chelemys. Anita had 6 male Abrothrix, 1 female Abrothrix, and 3 Chelemys. The "mordax" line in the yareta had 1 Abrothrix and several sprung and dragged Museum Specials. Female Abrothrix were pregnant and one Abrothrix was only about 20g. The Chelemys were pregnant also, and both male Auliscomys were breeding. These mice could not
