Cerro Plata is the highest summit of the Cordon del Plata and for a long time was considered to be over 6,000m. It lies south of Vallecitos, but both normal routes are generally accessed from the Salto base camp. On September 25 Rodrigo Maique and Sebastian Ruiz (Argentina) climbed a new route on the east face. They approached on the 22nd, via Quebrada de la Angostura, and thoroughly acclimatized before setting off from camp at 3:30 a.m. Climbing through scree and penitentes, they reached a couloir. Where it split, they took the left branch. (The right branch had been climbed in 1980 by Alessio and Mon.) At first the angle was 40° over iced scree, then it steepened to 55° snow and ice. They eventually emerged onto the east ridge and reached the summit, which has marvelous views northwest to Aconcagua. They descended a couloir of less than 40° to regain camp and named the route Falto la Gorda.
