The Coso volcanic field at the western edge of the Basin and Range province consists of largely Pliocene to late-Pleistocene rhyolitic lava domes and basaltic cinder cones covering a 400 sq km area.  This view looks south across the range from Cactus Peak with some of the 38 light-colored rhyolitic lava domes of the Coso volcanic field in the foreground and dark-colored basaltic cinder cones and associated lava flows in the background.  Active fumaroles and thermal springs are present in an area that is a producing geothermal field.  Photo by Paul Kimberly, 1997 (Smithsonian Institution).
