Mount McKinley is in the back round of this perfectly clear day in Don Sheldon's Amplitheater. This photo was taken on May 20, 2010 on the Ruth Glacier after a landing with K2 Aviation. Don Sheldon was an innovator when it came to aviation in Alaska and throughout his bush pilot career. He made his name helping Bradford Washburn survey Denali (aka Mount McKinley) in the late 1940's for the Boston Museum of Science, by being one of the first pilots to have the nerve to land on a glacier.

To land on a glacier, Sheldon would make a low pass just yards above his projected landing area to check out his runway. This would be done to verify that there was sufficient snow coverage and no crevices were not exposed. Once all looked good, Sheldon would make his final landing.

Besides being one of the innovators of glacier landings Sheldon received recognition for making various rescues in his single engine planes.
