English: The Cerro Bayo volcanic complex lies along the Chile-Argentina border east of the Salar de Gorbea, the light-colored area at the left-center portion of this NASA Landsat image. A young well-preserved crater can be seen NE of an older snow-covered center (bottom-center). A younger northern center along the national border has a well-preserved 400-m-wide crater. The 5401-m-high summit of the Cerro Bayo complex, located west of the border in Chile, is the source of two viscous dacitic lava flows with prominent levees that traveled to the north.
