This image taken Jan. 14, 2015, acquired by the Operational Land Imager (OLI) on Landsat 8, shows the glaciers of Sierra de Sangra, an icy stratovolcano spanning the border of Chile and Argentina. Snow and ice are blue in these false-color images, which use different wavelengths to better differentiate areas of ice, rock, and vegetation.

Since the end of the Little Ice Age, the ice fields of Patagonia and other parts of South America have been shrinking as have increased. A number of studies have investigated these changes, which can affect the communities downstream that rely on the glaciers for a steady water supply.
