Mount Johnson is an mountain summit located in the Alaska Range, in Denali National Park and Preserve, in Alaska, United States. It is situated on the west side of the Ruth Gorge, southeast of Denali and south-southwest of The Moose's Tooth. Its nearest higher peak is Mount Wake, to the northwest. Despite its relatively low elevation, it is notable for its north face with over 4,000 feet of vertical sheer granite with climbing routes called the Escalator and Stairway to Heaven. The first ascent of the peak was made in 1979 by Gary Bocarde, Charlie Head, John Lee, and Jon Thomas via the south ridge. The mountain was named by famed explorer Dr. Frederick Cook who claimed the first ascent of Mount McKinley in 1906, but was later disproved.
