Retana caldera, between Suchitán and Tahual volcanoes, is a prominent steep-walled caldera once filled by Laguna Retana. The lake periodically became dry and was refilled in the 19th and 20th centuries and has now been drained to provide access to rich soils on the lake floor. A canal drains the lake through a notch on its northern rim (extreme right). The caldera is seen here from its eastern rim (on the flank of Suchitán volcano). Volcán Tahual is the forested volcano behind the caldera at the right-center.
