On September 21, 2015, the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite captured this true-color image of southern Chile (west) and Argentina (east) as it flew over Patagonia on a late winter day.

The Andes Mountains stretches north to south roughly along the border between the two countries and is crowned by the Southern Patagonian Ice Field. Covering an area of about 13,000 sq. km. (5,019 sq. mi.), with a length of about 360 km (224 mi) and an average width of about 40 km (24.8 mi), the Southern Patagonian Ice Field is the second largest contiguous ice field in the Southern Hemisphere (the first is Antarctica).

On the eastern side of the ice field, the run-off from glaciers form large lakes, such as the three milky blue lakes in this image: Lago San Martin, Viedma Lake, and Lago Argentina (from north to south). Viewed at high resolution, the glacial tongues can be viewed at the source of each of these lakes.
