Artesonraju. During July and August 1974, an Argentinian expedition of the Centro Andino Buenos Aires was active in the Cordillera Blanca. Bad weather defeated several attempts to climb Alpamayo by both the north and south ridges. An attempt on Artesonraju (6025 meters, 19,766 feet) was, however, successful. The peak was climbed in mid-August. Climbers were R. Alvarez, H. Cuiñas, F. Olaechea, A. Perazzo, M. Serrano, G. Varoli and G. Vieiro (leader).
