At some , the base-to-peak rise is the largest of any mountain situated entirely above sea level. With a topographic prominence of and a topographic isolation of , 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 1917–2015. 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 high,〔 not , as measured in 1952 using photogrammetry. ==Geology and features== Denali is a granitic pluton lifted by tectonic pressure from the subduction of the Pacific Plate beneath the North American Plate; at the same time, the sedimentary material above and around the mountain was stripped away by erosion. The forces that lifted Denali also cause many deep earthquakes in Alaska and the Aleutian Islands. The Pacific Plate is seismically active beneath Denali, a tectonic region that is known as the "McKinley cluster". Denali has a summit elevation of above sea level, making it the highest peak in North America and the northernmost mountain above 6,000 meters elevation in the world.〔 Measured from base to peak at some , it is also the largest of any mountain entirely above sea level.〔 Denali rises from a sloping plain with elevations from , for a base-to-peak height of . By comparison, Mount Everest rises from the Tibetan Plateau at a much higher base elevation. Base elevations for Everest range from on the south side to on the Tibetan Plateau, for a base-to-peak height in the range of .〔 Prepared for the Boston Museum of Science, the Swiss Foundation for Alpine Research, and the National Geographic Society〕 Denali's base-to-peak height is little more than half the of the volcano Mauna Kea, which lies mostly under water.〔(【引用サイトリンク】url=http://science.nationalgeographic.com/science/earth/surface-of-the-earth/mountains-article/ )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Denali」の詳細全文を読む スポンサード リンク
