Photo by Jim Luhr, 1990 (Smithsonian Institution). A vertical aerial photo shows the nested craters of Volcán Riveroll (right-center) and the intersecting craters of Volcán Basu (below and to the left). The Riveroll craters are breached to the NW (upper left). Dark-colored basaltic lava flows extend to the SE from both cinder cone complexes. The flow from Riveroll diverts around the Kenton cinder cone at the lower right. The light-colored areas are windblown sand. The Pacific coast shoreline is at the left, and the body of water at the upper right is part of San Quintín Bay.
