Aconcagua, New Route on the West Face. The west face of Aconcagua is seen at advantage from the Plaza de Mulas. It is very wide and has room for many variants. After leaving the Plaza de Mulas, Argentines Daniel Alessio and Daniel Rodríguez placed three high camps. They found 150-foot rock walls alternating with gullies of rotten rock, ice cascades and tongues of very hard frozen snow (UIAAIV to VI). On January 11 in the last 500 feet they reached the southwest ridge and the summit.
