Cerro Negro de Mayasquer, astride the Colombia-Ecuador border, is a stratovolcano with a caldera open to the west. Andesitic and dacitic lava flows are of possible Holocene age (Hall 1992, pers. comm.). Solfataras are found on the shore of a small crater lake. An historical eruption reported in 1936 may have been from Reventador (Catalog of Active Volcanoes of the World). The higher, glacier-covered summit of the Pleistocene Chiles stratovolcano lies only 3 km to the SE. Chiles last erupted about 160,000 years ago, but has hot springs and an active hydrothermal system at its eastern flank.
