Aconcagua, South Face. Argentines made an ascent and descent of the south face of Aconcagua. They were Guillermo Vieiro, Jorge Vitón, Fermín Olaechea, Héctor Cuiñas, Felipe Frasson and Eliseo Busto. They were on the mountain 17 days. This is the first time that a party on this difficult route has also descended the wall.
