The small volcanic center with the crater outlined by snow just to the left of the bottom center of this NASA International Space Station image (with north to the upper right) is Cerro Pantoja. This eroded basaltic-andesite volcano of Pleistocene age along the Chile-Argentina border has a Holocene cinder cone on the Argentinian side. The deep blue lake at right-center is Lago Constancia, and the large stratovolcano with a snow-filled summit crater at the top of the image is Puyehue.
