Cerro Negro de Mayasquer
- VolcanoCerro Negro de Mayasquer is an andesitic to dacitic stratovolcano on the Colombia-Ecuador border. It contains a caldera open to the west. An historical eruption reported in 1936 is probably false and may have been from Reventador volcano. Solfataras are found on the shore of a small crater lake.
