Hiking in Mount McKinley, Alaska: trails, map and practical info

Denali /dᵻˈnɑːli/ (also known as Mount McKinley, its former official name) is the highest mountain peak in North America, with a summit elevation of 20,310 feet (6,190 m) above sea level. At some 18,000 ft (5,500 m), the base-to-peak rise is the largest of any mountain situated entirely above sea level. With a topographic prominence of 20,156 feet (6,144 m) and a topographic isolation of 4,629 miles (7,450 km), Denali is the third most prominent and third most isolated peak after Mount Everest and Aconcagua. Located in the Alaska Range in the interior of the U.S. state of Alaska, Denali is the centerpiece of Denali National Park and Preserve. The Koyukon people who inhabit the area around the mountain have referred to the peak as "Denali" for centuries. In 1896, a gold prospector named it "Mount McKinley" in support of then-presidential candidate William McKinley; that name was the official name recognized by the United States government from 1917 until 2015. In August 2015, following the 1975 lead of the state of Alaska, the U.S. Department of the Interior announced the change of the official name of the mountain to Denali. Prior to this, most Alaskans already referred to the mountain as Denali. In 1903, James Wickersham recorded the first attempt at climbing Denali, which was unsuccessful. In 1906, Frederick Cook claimed the first ascent, which was later proven to be false. The first verifiable ascent to Denali's summit was achieved on June 7, 1913, by climbers Hudson Stuck, Harry Karstens, Walter Harper, and Robert Tatum, who went by the South Summit. In 1951, Bradford Washburn pioneered the West Buttress route, considered to be the safest and easiest route, and therefore the most popular currently in use. On September 2, 2015, the U.S. Geological Survey announced that the mountain is 20,310 feet (6,190 m) high, not 20,320 feet (6,194 m), as measured in 1952 using photogrammetry.
