A cluster of cinder cones of the Camargo volcanic field lies within the arid northern Bolsón de Mapimí graben in north-central México, about 150 km SW of Big Bend National Park in Texas. More than 300 volcanic vents, mostly cinder cones and lava cones, are located in a broad 2500 km² lava plateau that extends 60 km E-W and 70 km N-S. The Camargo field is mostly Pliocene in age, but activity continued into the Pleistocene.
