Two dramatically different volcano morphologies are visible in this photo of Las Pilas volcanic complex. Conical 818-m-high Asososca stratovolcano (left foreground) has a pronounced erosional valley on its southern flank. Broad Las Pilas volcano (right background) rises to 1088 m and has a more complex volcanic history. These are the two most prominent of a roughly 30-km-long chain of N-S-trending vents.
