Mercedario

Mercedario is the fourth highest mountain in South America, behind Aconcagua, Ojos del Salado, and Monte Pissis. Mercedario is a huge eroded volcano, located less than fifty miles north of Aconcagua. Each of the two peaks dominates the view from the other's slopes. Mercedario, like Aconcagua, is a gently sloping mountain, and is a relatively easy climb.
