Cook's claimed photograph of the summit of Mt. McKinley.
Fake Peak is a small outcrop on a ridge beside the Ruth Glacier in Denali National Park and Preserve in Alaska, USA, 19 miles southeast of the summit of Mount McKinley. It has been shown by Robert M. Bryce that the "summit photograph" produced by Frederick Cook as evidence supporting his claim to have made the first ascent of McKinley was in fact taken on Fake Peak. At 5,338 ft, this is almost 15,000 ft lower than the true summit of McKinley.
