Denali in Alaska has the highest mountain peak in North America. The mountain has a summit elevation of 20,310 feet (6,190 m) and a base-to-peak rise of approximately 18,000 ft (5,500 m). Since 1896, the mountain had been officially called Mount McKinley in support of the then-presidential candidate William McKinley. After decades of efforts, the name was changed in August 2015 to Denali as this is what Alaskans, mountaineers and native Alaskans had called the mountain for years. The word is based on the native Alaskan Koyukon word “Deenaalee”, meaning “the high one”.
