The Tupungato volcano (Huarpe word that means: “viewing point of the stars”) is a stratovolcano located at the Andes mountain range in the frontier of Argentina and Chile.
Due to its great height, it has the privilege of being one of the tallest volcanoes of South America. Precise measure methods have given as result a height of 6,750 meters above sea level.
It is the highest mountain of the Andes at the South of the Aconcagua Mountain and it dominates its surrounding areas with its enormous size and its representative cone, which exceeds in many meters the neighboring summits. It is geologically considered an extinct volcano of the Pleistocene times; even if the Holocene volcano Tupungatito, located immediately at the South-West, with which it is often confused, is active having at least eighteen registered eruptions since 1829, the last ones being soft ash emissions in 1980 and 1986.
This volcano is visible from the valleys of the centre-North of the Province of Mendoza; from the city of Santiago de Chile, its vision is obstructed due to the numerous ridges before it; however, at the extreme South of the Chilean capital (Puente Maipo of the North-South) it is possible to see it. From its sides, the Colorado River has its source, which finally flows into the Maipo River, in Chile.
