Mt. McKinley at 20,320 feet is the tallest mountain in North America. It is in Denali National Park, Alaska. I flew out of Talkeetna a small airport that flies all the climbers up to the glaciers to start their climbs. It was just me and the pilot, we were in a high wing Cessna. This plane is great for aerial photography because you can open the window with an unobstructed view, thus no plane wings in your foreground.
