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.
