Three major Quaternary volcanic complexes are visible in this Landsat satellite image of Baja California. The N-S-trending Las Vírgenes volcanic complex to the left consists of three stratovolcanoes that are progressively younger towards the south. The 10-km-wide La Reforma caldera along the Gulf of California coast to the right displays darker andesite flanks and a resurgent dome in the center. The extensively eroded El Aguajito caldera has indistinct margins but the large resurgent dome forms the roughly circular eroded hills west of La Reforma.
