The Pinacate volcanic field covers approximately 55 x 60 km and contains numerous maars and scoria cones. The field is prominent in this arid region of NW México near the head of the Gulf of California. The crater rim across the center of the photo is the 1.6-km-wide Cráter Elegante maar. Pinacate Peak in the distance is at the summit of Santa Clara shield volcano, which contains many scoria cones and lava flow fields.
