Cráter Elegante, seen here in an aerial oblique view from the NW, is a 1.6-km-wide maar in the Pinacate volcanic field. Within the crater walls are exposed basaltic lava flows, sills, and dikes pre-dating formation of the maar, which are overlain by pyroclastic surge deposits that cover the rim and outer flanks. Lake beds within the maar have been radiocarbon dated at between about 13,000 and 17,000 years, indicating a late-Pleistocene age for the maar-forming eruptions.
