Cerro Cajón Perdido. Attempts. More than 20 climbers, which included Italians from Venice and Argentinians from the town of General Alvear, joined forces for a campaign among the little known peaks of the southern part of the province. They climbed Cerro Alvear (4534 meters, 14,878 feet), the south face of Risco Plateado (4920 meters, 16,142 feet) and explored the unclimbed east face of Sosneado (5189 meters, 17,025 feet). Their main objective, Cerro Cajón Perdido (4660 meters, 15,291 feet), a fine rock cathedral, repulsed all attempts. In one the climbers reached some 150 feet below the final rock tower, but had to retreat on account of the steepness of the unstable rock. Leaders were Francesco Santon, Italian, and Guillermo Rodríguez, Argentinian.
