MF Smith 1993 JOURNAL Bariloche, Prov. Rio Negro, Argentina Mon Dec. 6 We released all except the Abrothrix xanthorhina and drove back to town. I processed the two dead Abrothrix xanthorhina while Payne talked with Michael Christie about their poster. At 11:00 am Payne and I drove north past the site where Eileen Lacy is studying Ctenomys sociabilis and on to the Incaful Valley. Payne took a habitat shot of one of the caves where they found amber, similar to the woodrat amber in the western US. We also climbed around at the entrance to a cave where Michael Christie had found amber, trying to find a sample to show with their poster. We didn't find any very good examples. I got a picture of the cave where Payne has analyzed the bones from owl pellets over the last several thousand years. The weather was very good today, the clearest day we have had, after a week of rain that was very welcome. When we got back to Bariloche we processed the rest of the animals from El Condor. Milton Hallards was expected at the Pearsons, but didn't show up today.
