The NW-most dome of the twin Las Derrumbadas lava domes, seen here from the NE along the highway to Perote, has undergone extensive hydrothermal alteration. Fumaroles on the domes remain active. The eroded hillside near the center is the outer flank of the San Luis Atexcac tuff ring, which contains a crater lake.
