MF Smith 1993 JOURNAL Rio Castaño Overs Nov.24 was able to pull the van out on the first try. It was too late to drive up to see the glacier today because the traffic is one way going down after 4pm, and we needed to get to our next site to get the traps out. We drove down a gravel road past a quarry to a cow pasture along the upper Rio Manso just above where the river flows into Lago Mascardi. Payne thinks this is only a kilometer or so from Juli's Contreras' type locality for A. mansoensis. Much of the area seemed to be overgrazed, but we set in bushes near as much tall grass as possible. We set 165 traps. Payne grilled steaks for dinner. During the night we had snow again, even though we were farther east and lower in elevation. This kind of storm is unusual this late in the spring (equivalent to the end of May in the US). Lago Mascardi (west end), Prov. Rio Negro, Argentina Nov.30 In spite of the snow we caught several animals here: 9 - Abrothrix olivaceus (same thing as mansoensis?) 1 - Oligoryzomys longicaudatus 1 - Abrothrix longipilis
