The oldest volcanic center of the San Cristóbal volcanic complex is La Pelona caldera, whose eastern wall forms the forested ridge in the center of the photo.  Formation of the caldera was accompanied by the eruption of large amounts of dacitic pumice.  Part of the caldera floor is visible at the left, but the western rim and floor has been buried by products of Casita volcano, where this photo was taken.  The Marrabios Range volcanoes of Telica, Las Pilas, and conical Momotombo can be seen in the distance. Photo by Lee Siebert, 1998 (Smithsonian Institution).
