The 2048-m-high Mondaca lava dome (bottom center) produced a large youthful rhyodacitic lava flow that traveled north and dammed the Rio Lontue, eventually reaching 7 km to the NW (upper right). This eruption may have taken place during historical time, possibly during the 19th century. The solitary small Mondaca lava dome is located NNW of the Descabezado volcano complex and west of the Calabozos caldera.
