STS084-708-025 Coropuna and Soliman Volcanoes, Peru May 1997 This image shows two magnificent, snow-covered stratovolcanoes located in the Andes Mountains of southern Peru. Just to the left of center lies the 21080 foot (6419 meters) Coropuna Volcano. To the west (above) sits Solimana with at an altitude of 20069 feet (6121 meters). Both have been dormant for the past 100,000 years. To the west (top center and top left of the image) is the deep canyon of the Colohuasi River, which merges with the Ocona River (upper left). As the Andes have continued to rise, these rivers, which flow into the Pacific Ocean, have kept pace by eroding deep canyons and valleys.
