Tecuamburro, seen here from the SE on the Pacific coastal plain, is a small, forested stratovolcano or lava-dome complex of mostly Pleistocene age.  Tecuamburro and other lava domes forming the right-hand peaks were constructed during the late Pleistocene or early Holocene within a horseshoe-shaped, east-facing caldera.  The caldera resulted from structural failure of the older Miraflores stratovolcano on the left.  The latest dated eruption from Tecuamburro formed Laguna Ixpaco, a phreatic tuff ring on the NW flank, about 2900 years ago. Photo by Lee Siebert, 1988 (Smithsonian Institution).
