The 26 x 14 km late-Pleistocene Calabozos caldera contains several post-caldera vents of Holocene age. The Descabezado Chico group (mid right-center) was constructed over the buried western rim of the caldera. The Cerro de Medio group (mid extreme-right) grew within the southern part of the caldera. No historical eruptions are known, but hot-spring clusters occur within the caldera.
