Cerro Escorial

Cerro Escorial is a stratovolcano located in the Andes on the border between Chile and Argentina. Its crater sits at the summit, and ancient lava flows spread across both countries.

The volcano experienced a major eruption roughly 460,000 years ago that ejected substantial material. A significant lava flow occurred around 342,000 years ago during a later episode.

The volcano stands within the territory where indigenous communities maintain connections to the volcanic formations through their traditions and daily practices.

Visitors should attempt the ascent only during stable weather, as this location sits at high elevation in an alpine setting. Warm clothing and proper gear are essential for safety and comfort.

The Escorial ignimbrite formation resulted from a substantial eruption 460,000 years ago, producing 0.6 cubic kilometers of dacitic material.
