JPMajors 1974 Camp list 50 Km W of Villa Mascardi by road, 300', Provincia de Rio Negro, Argentina 17 May camped on edge of moraine from glacier on Mount Tronador, beside a small stream. Rained throughout the night, and snow accumulated not too far above us (in fact some of our rain was mixed w/snow.) Nothofagus pumilio, N. antarctica, and N. dombeyi were present. The Chusquea colchica and other lower plants forming a very dense ground cover. Colaptes pitius Dendrocygnes lignaris (1) Campephilus magellanicus (3) Aphrastura spinicuda 100+ in several large mixed feeding flocks Pygarrhichas albogularis - 10 with Aphrastura Scytalopus magellanicus ± 15 Km N of El Bolivian by road, on Arroyo de los Repolles, altitude: Provincia de Rio Negro, Argentina 17 May altitude = 1800' partly logged Araucaria forest with a few undulate - interspersed Nothofagus many Rosa, a few Aristotelia magui. The bottom of the river in valley, is not wide - less than 200m across, and much if it has been cleared, probably by leaves/leaves near our camp. The river itself is ~10m across where there is only one channel. But in several places the water flows in several channels each under 5m across. Water is shallow; few pools appear to be over 30cm to 1m deep. It is a fast rushing stream, + obviously runs much higher at times of the year. During the evening of 18 May when we arrived, the rain showed signs of (melting cap - extensive cloudless patches). But about 0630 rain began again + has continued all day. Some mixed snow.
