The Southern Andes of South America as seen from STS-60

STS060-85-000AH (3-11 Feb 1994) --- This view is centered at about 44 degrees south along the Chilean continental margin of South America. The dark-colored coastal region is heavily forested by dense old-growth forests that are now being cut, but east of the mountains in Argentina the dry climate supports very little vegetation. This desert region known as Patagonia appears as light brown colors. The coastline is especially dramatic because it is shaped by the tortuous channels carved by glaciers which have left fjords. These fjords have effectively cut across the continental divide, and are bordered by active volcanoes which reach elevations between 2, 000 - 3,000 meters. The prominent volcanic peak in the center of the frame is Mt. Melimoya. To the north is a long, snow-covered volcanic ridge called Cerro Yantales. Cerro Yantales recently reported greatly increased fumarolic activity, including the emission of yellow gases near the summit. Russian and American scientists will use this photography to look for further evidence of increased activity like snow melt around the peak. Other Russian and American scientists are particularly interested in mapping the summertime snowline and firm (permanent snow field) elevations as early indications of any potential climatic variation in the making.
