Last eruption

Cerro Negro de Mayasquer (Ieft) and snow-capped Volcán Chiles (right), seen here from the south, are twin volcanoes that straddle the Colombia-Ecuador border.  Chiles volcano is of Pleistocene age, but has hot springs and an active hydrothermal system on its eastern flank.  Cerro Negro de Mayasquer is a stratovolcano with a caldera open to the west.  Andesitic and dacitic lava flows are of possible Holocene age.  Solfataras are found on the shore of a small crater lake.
