A lava flow of the Pleistocene-to-Holocene Palei-Aike volcanic field is seen here from Cerro del Diablo. The large volcanic field straddles the Chile/Argentina border north of the Straits of Magellan. The southernmost of the Patagonian basaltic plateau lavas, Palei-Aike contains lake-filled maars and basaltic scoria and spatter cones with associated fresh-looking lava flows.
