La India Dormida ("The Sleeping Indian") is a portion of the western rim of El Valle de Antón caldera that forms a distinctive profile. A popular hiking trail leads to the saddle (left) at the foot of La India Dormida and then to its head, which rises 300 m above the flat caldera floor. The caldera wall exposes deposits of Tertiary Iguana pyroclastic flows that are capped by the Tertiary Piedra andesitic lava flow.
