South America, Argentina, Dos Picos, Cordillera del Río Tigre

Dos Picos, Cordillera del Río Tigre. Three expeditions visited this rugged region, which lies about 80 miles south of Bariloche, west of Cholila. The members of the Club Andino Esquel, who made the first ascent of the south (highest) tower of the Cerro Dos Picos (8,300 feet), Señores Eggmann, Hardt, and Porcel, said that the ascent was "serious but without very great difficulties.” Señores Cazaux and Michel of the Centro Andino de Buenos Aires several weeks later climbed the northern tower, which they classified as exceptionally difficult. In March and April Dr. J. J. Neumeyer, Dr. Venzano, Birger Lantschner and M. Marqués of the Club Andino Bariloche explored this region further, during which they made the first ascent of a peak they called Cerro Orion.
