Red Cone (center) is the largest of a group of isolated basaltic scoria cones and lava flows on the floor of the Rose Valley in the western part of the Coso volcanic field. The late-Pleistocene scoria cone is seen here from the NE, with the towering fault scarp of the Sierra Nevada Range in the background. Highway 395 traverses Rose Valley between the cone and the Sierras.
