Lake Junin, Andes Mountains, Peru June 1993. The dark feature in the center of the color infrared image is Lake Junin. Located at approximately 13393 feet (4082 meters) above sea level, Lake Junin is about 90 miles (145 kilometers) northeast of Lima in the Andes Mountains. Numerous erosional stream channels and deep canyons are visible at the top (northeast) of the image. The rivers drain eastward and eventually flow into the Amazon Basin of eastern Peru. Notice that there is a redder border that encircles three-quarters of the lake (except the southwest coast). This is an indication that healthy green vegetation (green, chlorophyll-bearing vegetation is portrayed as reddish hues in color infrared images) can be mapped around most of the periphery of the lake. The lake measures roughly 25 miles (40 kilometers) in length and approximately 9 miles (15 kilometers) in width. Some of the mountainous terrain immediately southwest of the lake shows an intensively folded, northwest- aligned landscape.
