The irregular ridge on the horizon is the SE rim of the compound 5-km-wide Tepetiltic caldera.  The NE caldera was offset from the center of the stratovolcano and its rim is lower to the NE (right).  The flanks of the andesitic-dacitic stratovolcano are blanketed by deposits of rhyodacitic ash and pumice from the caldera-forming eruptions.  Cinder cones on the NW and SE flanks of the volcano erupted alkalic lava flows.   Photo by Lee Siebert, 1997 (Smithsonian Institution).
