The inner caldera rim of Ceboruco forms the ridge extending across the photo in this view looking toward the SE from near the summit. The inner caldera wall consists of massive dome lavas that were emplaced within the outer caldera. The unvegetated lava flow in the foreground was erupted from a vent within a scoria cone complex at the western side of the inner caldera, probably in 1870. Flat-topped Volcán Tequila forms the peak in distance to the upper right.
