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. · Foto: Photo by Minard Hall, 1985 (Escuela Politécnica Nacional, Quito)
