Incahuasi

Incahuasi is a volcanic mountain in the Andes of South America. It lies on the border of the Catamarca Province of Argentina and the Atacama Region of Chile. Incahuasi has a summit elevation of 6,621 metres above sea level.

The volcano consists of a 3.5-kilometre-wide caldera and two stratovolcanoes. Four pyroclastic cones located 7 kilometres to the northeast have produced basalt-andesite lava flows that cover an area of 10 square kilometres.
