Earth from space: Mt. McKinley, Alaska

The Operational Land Imager on the Landsat 8 satellite captured this image of Denali, or Mt. McKinley, on June 16, 2013. The mountain, composed primarily of granite, is located in the heart of the Alaska Range and has two significant summits that rise above the Denali Fault. The South Peak is the taller of the two. As seen in the lower image, a number of glaciers slide from its slopes into surrounding valleys, including Ruth, Kahiltna, and Peters glaciers.
