Mount McKinley or Denali "The Great One" in Alaska is the highest mountain peak in North America, at a height of approximately 20,320 feet (6,194 m). It is the centerpiece of Denali National Park.
Mount McKinley has a larger bulk and rise than Mount Everest. Even though the summit of Everest is about 9,000 feet (2,700 m) higher as measured from sea level, its base sits on the Tibetan Plateau at about 17,000 feet (5,200 m), giving it a real vertical rise of a little more than 12,000 feet (3,700 m). The base of Mount McKinley is roughly a 2,000-foot plateau, giving it an actual rise of 18,000 feet (5,500 m).
The mountain is also characterized by extremely cold weather. A thermometer left exposed at an elevation of 15,000 feet (4,600 m) on Mount McKinley over 19 years recorded a temperature of −100 °F (−73.3 °C) at some point during its exposure. There is also an unusually severe risk of altitude illness for climbers, due to not only its high elevation but also its high latitude. At the equator, a mountain as high as Mount McKinley would have 47% as much oxygen available on its summit as there is at sea level, but because of its latitude, the pressure on the summit of McKinley is even lower.
Layout of the mountain
Mount McKinley has two significant summits: the South Summit is the higher one, while the North Summit has an elevation of 19,470 feet (5,934 m) and a prominence of approximately 1,320 feet (402 m). The North Summit is sometimes counted as a separate peak (see e.g., the List of United States fourteeners) and sometimes not; it is rarely climbed, except by those doing routes on the north side of the massif.
Five large glaciers flow off the slopes of the mountain. The Peters Glacier lies on the northwest side of the massif, while the Muldrow Glacier falls from its northeast slopes. Just to the east of the Muldrow, and abutting the eastern side of the massif, is the Traleika Glacier. The Ruth Glacier lies to the southeast of the mountain, and the Kahiltna Glacier leads up to the southwest side of the mountain.
Mount McKinley is commonly referred to by its native name Denali, which is the name currently recognized by the State of Alaska. When Denali National Park and Preserve was established by the Alaska National Interest Lands Conservation Act, December 2, 1980, the Alaska Board of Geographic Names changed the name of the mountain back to Denali. However, the U.S. Board on Geographic Names maintains the name McKinley, ostensibly to help visitors avoid confusion between the mountain and the park. Use of the name "McKinley" remains common, particularly in the Lower 48; however, Alaskans and mountaineers generally use the name "Denali" to refer both to the park and to the mountain.
