Erosional furrows cut outflow sheets of Pleistocene ignimbrites of the Purico Complex that were erupted from a postulated 10 x 20 km ring fracture. The light-colored dome at the top center is Pleistocene in age, but the youngest lava domes, Cerro Chascón de Purico (center) and Cerro Aspero (the small dome at the bottom center) are of Pleistocene-Holocene age. The dacitic-to-andesitic Macon stratovolcano of Holocene age lies at the SW end of the complex (far left-center). The Guayaques volcanic chain lies at the upper right.
