A panoramic view shows the crater ring of San Félix volcano, with Isla San Ambrosio on the horizon. San Félix Island, 800 km west of the Chilean coast, consists largely of a low lava platform separating two tuff cones. The Islota Gonzáles cone (right) is separated from the main island by a shallow submerged platform. Cerro Amarillo at the NW end of the island is the source of fresh-looking lava flows that reached the sea and formed the low lava platform.
