Peruvian Ascents. The following list of ascents in 1956 by Peruvians, as well as other important data, were provided by César Morales Arnao, of the Grupo Cordillera Blanca de Huaraz. Whether these are first ascents or not, is not clear. From the San Antonio de Esquilache mine, west of Puno, Gustavo Alencastre Montúfar climbed Sayhua, 18,996 feet, Caballuni, 18,964 feet, and Ankasillo, 18,340 feet. With Jorge Pakusich and Percy Cáceres, Alencastre climbed the west ridge of Huago- chullo, 18,209 feet, in the same region. Alfredo del Arroyo and Elsa Garrido Klinge climbed the west peak of the Nevado Anticona, 17,389 feet, July 39, and, on August 4, César Morales Arnao and José Tord Nicolini climbed the central peak, 17,161 feet, of the same mountain, from Ticlio by the south glacier.
