This photo looks east from Las Tortugas volcanic center towards the town of Atenguillo. Low hills just behind and sightly to the left of Atenguillo are eroded trachybasaltic lava flows of Pliocene age. The ridge in the background exposes late Cretaceous ashflow tuffs that make up the Atenguillo graben walls. Photo by Paul Wallace, 1998 (University of California Berkeley).
