The Pleistocene-Holocene Pinacate volcanic field encroaches on the Gran Desierto of Sonora, Mexico. The field includes one large shield volcano and several hundred cinder cones and associated lava flows. In addition, there are a number of maar volcanoes, the most prominent of which is the Elegante Crater. This is an active volcanic field and future eruptions are anticipated.
