The most prominent features of the Serdán-Oriental volcanic field are the two Las Derrumbadas lava domes. The NW (left) and SE (right) domes are of similar height and lithology and rise about 1 km above their bases. The Serdán-Oriental is a broad closed basin at the eastern end of the Mexican altiplano containing lava domes, tuff rings, lava flows, and scoria cones of late-Pleistocene to Holocene age. Several of the tuff rings, such as Laguna Atexcac and Laguna Alchichica, contain crater lakes.
