Twin Buttes, the two cinder cones at left-center, were formed SE of Burney Mountain, the prominent andesitic lava dome complex at the right.  Blocky, partially vegetated lava flows extend to the north from the cinder cones.  The twin cones are part of a large area of young volcanism located north of Lassen National Park.  Burney Mountain is a large dacitic complex of five overlapping lava domes of Pleistocene age. Photo by Lee Siebert, 1998 (Smithsonian Institution).
