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, who later became the 25th president; McKinley's name was the official name recognized by the federal government of the United States from 1917 until 2015. In August 2015, 40 years after Alaska had done so, the United States Department of the Interior under the Obama administration announced the change of the official federal name of the mountain to Denali.{{cite press release|title=Denali Name Change|url=https://www.doi.gov/sites/doi.gov/files/elips/documents/3337%20-%20Changing%20the%20Name%20of%20Mount%20McKinley%20to%20Denali.pdf|publisher=U.S. Department of the Interior|date=August 28, 2015|access-date=August 31, 2015|archive-date=October 8, 2018|archive-url=https://web.archive.org/web/20181008012637/https://www.doi.gov/sites/doi.gov/files/elips/documents/3337%20-%20Changing%20the%20Name%20of%20Mount%20McKinley%20to%20Denali.pdf|url-status=live}}{{cite web|last=Campbell|first=Jon|title=Old Name Officially Returns to Nation's Highest Peak|url=https://www.usgs.gov/news/old-name-officially-returns-nations-highest-peak|publisher=U.S. Board on Geographic Names (U.S. Geological Survey)|date=August 30, 2015|access-date=May 16, 2016|archive-date=June 5, 2016|archive-url=https://web.archive.org/web/20160605070047/https://www.usgs.gov/news/old-name-officially-returns-nations-highest-peak|url-status=live}}{{cite web |url=http://www.gpo.gov/fdsys/pkg/CRPT-113srpt93/html/CRPT-113srpt93.htm |title=Senate Report 113-93 – Designation of Denali in the State of Alaska |author=Mr. Wyden, from the Committee on Energy and Natural Resources |date=September 10, 2013 |publisher=U.S. Government Publishing Office |access-date=September 16, 2015 |quote=The State of Alaska changed the name of the mountain to Denali in 1975, although the U.S. Board on Geographic Names has continued to use the name Mount McKinley.

In 1903, James Wickersham recorded the first attempt at climbing Denali, which was unsuccessful. In 1906, Frederick Cook claimed the first ascent, but this ascent is unverified and its legitimacy questioned. 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 measured the mountain at {{convert|20310|ft|m|0|abbr=out}} high, 10 ft lower than the {{convert|20320|ft|m|0|abbr=out}} measured in 1952 using photogrammetry.

Geology and features

Denali is a granitic pluton, mostly pink quartz monzonite, 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.{{cite web|last=Brease|first=P.|title=GEO-FAQS #1 – General Geologic Features|url=http://www.nps.gov/dena/upload/Brief%20Geology%20of%20Mt.pdf|publisher=National Park Service|date=May 2003|access-date=March 17, 2013|archive-date=March 8, 2016|archive-url=https://web.archive.org/web/20160308043818/http://www.nps.gov/dena/upload/Brief%20Geology%20of%20Mt.pdf|url-status=live}}{{cite journal |url=https://journals.openedition.org/geomorphologie/147?lang=en |first1=Kenji |last1=Yoshikawa |first2=Yositomi |last2=Okura |first3=Vincent |last3=Autier |first4=Satoshi |last4=Ishimaru |date=2006 |title=Secondary calcite crystallization and oxidation processes of granite near the summit of Mt.

The Pacific Plate is seismically active beneath Denali, a tectonic region that is known as the "McKinley cluster".{{cite web |last=Hanson |first=Roger A. |title=Earthquake and Seismic Monitoring in Denali National Park |url=http://www.nps.gov/akso/nature/science/ak_park_science/PDF/2006Vol5-1/Earthquake-Monitoring.pdf |url-status=dead |archive-url=https://web.archive.org/web/20080210130333/http://www.nps.gov/dena/upload/Brief%20Geology%20of%20Mt.pdf |archive-date=February 10, 2008 |access-date=March 17, 2013 |publisher=National Park Service |pages=23–25}}

= Structural geology =

The high topography of Denali is related to the complex structural relationships created by the right-lateral Denali Fault and Denali Fault Bend. The Denali Fault is caused by stresses created by the low-angle subduction of the Yakutat microplate underneath Alaska. The Denali Fault Bend is characterized as a gentle restraining bend.{{Cite journal |last=Burkett |first=Corey |title=Along-fault migration of the Mount McKinley restraining bend of the Denali fault defined by late Quaternary fault patterns and seismicity, Denali National Park & Preserve, Alaska |journal=Tectonophysics |date=2016 |volume=693 |pages=489–506 |doi=10.1016/j.tecto.2016.05.009 |bibcode=2016Tectp.693..489B |hdl=10919/101887 |hdl-access=free }} The Denali Fault Bend represents a curvature in the Denali Fault that is approximately 75 km long. This curvature creates what is known as a "space problem". As the right-lateral movement along the Denali Fault continues, high compressional forces created at the fault bend essentially push the crust up in a vertical fashion. The longer the crust stays within the restraining bend, the higher the topography will be. Several active normal faults north of the restraining bend have recently been mapped with slip rates of approximately 2–6 mm/year. These normal faults help to accommodate the unusual curvature of the restraining bend.{{citation needed|date=March 2024}}

=Geography of the mountain=

Denali has two significant summits: the South Summit is the higher one, while the North Summit has an elevation of {{convert|19470|ft|m|0|abbr=on}} and a prominence of approximately {{convert|1270|ft|m|0|abbr=on}}.{{cite peakbagger |pid=270 |name=Mount McKinley-North Peak, Alaska |access-date=March 18, 2013}} The North Summit is sometimes counted as a separate peak (see e.g., fourteener) 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.{{cite web|title=Denali National Park and Preserve|url=http://denali.areaparks.com/parkinfo.html?pid=7821|archive-url=https://archive.today/20130410125354/http://denali.areaparks.com/parkinfo.html?pid=7821|archive-date=April 10, 2013|publisher=AreaParks.com|access-date=March 18, 2013}}{{cite web|title=Denali National Park|url=http://www.planetware.com/tourist-attractions-/denali-national-park-us-ak-dp.htm#US-AK-MM|publisher=PlanetWare|access-date=March 18, 2013|archive-date=December 2, 2013|archive-url=https://web.archive.org/web/20131202234319/http://www.planetware.com/tourist-attractions-/denali-national-park-us-ak-dp.htm#US-AK-MM|url-status=live}} With a length of {{convert|44|mi|abbr=on}}, the Kahiltna Glacier is the longest glacier in the Alaska Range.

Naming

{{main|Denali–Mount McKinley naming dispute}}

The Koyukon Athabaskans who inhabit the area around the mountain have for centuries referred to the peak as {{Lang|koy|Dinale}} or {{Lang|koy|Denali}}. The name is based on a Koyukon word for 'high' or 'tall'.{{cite news |url= http://www.adn.com/article/20150830/it-s-official-it-s-denali |title=McKinley no more: America's tallest peak to be renamed Denali |last=Martinson |first=Erica |date=August 30, 2015 |newspaper=Alaska Dispatch News |access-date=August 31, 2015 |quote=The name "Denali" is derived from the Koyukon name and is based on a verb theme meaning "high" or "tall," according to linguist James Kari of the Alaska Native Language Center at the University of Alaska Fairbanks, in the book "Shem Pete's Alaska."

In 1896, a gold prospector named it McKinley as political support for then-presidential candidate William McKinley, who became president the following year.

=Climbing history=

During the summer of 1902 scientist Alfred Brooks explored the flanks of the mountain as a part of an exploratory surveying party conducted by the U.S. Geological Survey. The party landed at Cook Inlet in late May, then traveled east, paralleling the Alaska Range, before reaching the slopes of Denali in early August. Camped on the flank of the mountain on August 3, Brooks noted later that while "the ascent of Mount McKinley had never been part of our plans", the party decided to delay one day so "that we might actually set foot on the slopes of the mountain". Setting off alone, with good weather, on August 4, Brooks aimed to reach a {{convert|10,000|ft|m|0|abbr=out}} shoulder. At {{convert|7,500|ft|m|0|abbr=out}}, Brooks found his way blocked by sheer ice and, after leaving a small cairn as a marker, descended.{{Cite book|url=https://www.nps.gov/parkhistory/online_books/dena1/history.pdf|title=A History of Mount McKinley National Park|last=Person|first=Grant|publisher=United States Department of the Interior|year=1953|pages=9–12|access-date=August 15, 2019|archive-date=August 3, 2019|archive-url=https://web.archive.org/web/20190803082633/https://www.nps.gov/parkhistory/online_books/dena1/history.pdf|url-status=live}} After the party's return, Brooks co-authored a "Plan For Climbing Mt McKinley", published in National Geographic magazine in January 1903, with fellow party-member and topographer D. L. Raeburn, in which they suggested that future attempts at the summit should approach from the north, not the south.{{Cite book|title=To The Top of Denali: Climbing Adventures on North America's Highest Peak|last=Sherwonit|first=Bill|publisher=Alaska Northwest Books|year=2012|isbn=978-0-88240-894-1}} The report received substantial attention, and within a year, two climbing parties declared their intent to summit.{{Cite book|title=Distant Vistas: Bradford Washburn, Expeditionary Science and Landscape 1930–1960|last=Sfraga|first=Michael|year=1997|page=256}}

During the early summer of 1903, Judge James Wickersham, then of Eagle, Alaska, made the first recorded attempt to climb Denali, along with a party of four others. The group attempted to get as close to the mountain as possible via the Kantishna river by steamer, before offloading and following Chitsia Creek with a poling boat, mules and backpacks, a route suggested to them by Tanana Athabaskan people they met along the way. The party received further navigational assistance at Anotoktilon, an Athabaskan hunting camp, where residents gave the group detailed directions to reach the glaciers at the foot of Denali. On reaching the mountain, the mountaineers set up base camp on the lower portion of Peters Glacier. Aiming for the northwest buttress of Denali's north peak, they attempted to ascend directly; however, crevasses, ice fall and the lack of a clear passage caused them to turn and attempt to follow a spur via Jeffery Glacier where they believed they could see a way to the summit. After a dangerous ascent, at around {{convert|10,000|ft|m|0|abbr=out}}, Wickersham found that the route did not connect as it had appeared from below, instead discovering "a tremendous precipice beyond which we cannot go. Our only line of further ascent would be to climb the vertical wall of the mountain at our left, and that is impossible." This wall, now known as the Wickersham Wall, juts {{convert|15,000|ft|m|0|abbr=out}} upwards from the glacier to the north peak of Denali.{{Cite web|url=https://www.nps.gov/parkhistory/online_books/dena/hrs3.htm|title=Denali NP: Historic Resource Study (Chapter 3)|publisher=National Park Service|access-date=August 20, 2019|archive-date=October 7, 2019|archive-url=https://web.archive.org/web/20191007022143/https://www.nps.gov/parkhistory/online_books/dena/hrs3.htm|url-status=live}} Because of the route's history of avalanche danger, it was not successfully climbed until 1963.{{sfn|Beckey|1993|p=139}}

Later in the summer of 1903, Dr. Frederick Cook directed a team of five men on another attempt at the summit. Cook was already an experienced explorer and had been a party-member on successful arctic expeditions commanded both by Robert Peary and Roald Amundsen.{{Cite book|title=Continental Divide: A History of American Mountaineering|last=Isserman|first=Maurice|publisher=W.

The party navigated up the Cook inlet and followed the path of the 1902 Brooks party towards Denali. Cook approached the mountain via the Peters Glacier, as Wickersham had done; however, he was able to overcome the ice fall that had caused the previous group to turn up the spur towards the Wickersham Wall. Despite avoiding this obstacle, on August 31, having reached an elevation of about {{convert|10,900|ft|m|0|abbr=out}} on the northwest buttress of the north peak, the party found they had reached a dead end and could make no further progress. On the descent, the group completely circumnavigated the mountain, the first climbing party to do so.{{sfn|Beckey|1993|p=295}} Although Cook's 1903 expedition did not reach the summit, he received acclaim for the accomplishment, a {{convert|1000|mi|0|abbr=out}} trek in which he not only circled the entire mountain but also found, on the descent, an accessible pass northeast of the Muldrow Glacier following the headwaters of the Toklat and Chulitna rivers.

In 1906, Cook initiated another expedition to Denali with co-leader Herschel Parker, a Columbia University professor of electrical engineering with extensive mountaineering experience. Belmore Browne, an experienced climber and five other men comprised the rest of the group. Cook and Parker's group spent most of the summer season exploring the southern and southeastern approaches to the mountain, eventually reaching a high point on Tokositna glacier, {{convert|25|mi|0|abbr=out}} from the summit.{{sfn|Beckey|1993|p=295}} During their explorations the party mapped out many of the tributaries and glaciers of the Susitna river along the mountain's south flank. As the summer ended, the team retreated to the coast and began to disperse. In September 1906, Cook and a single party-member, horseman Robert Barrill, journeyed towards the summit again, in what Cook later described as "a last desperate attempt" in a telegram to his financial backers. Cook and Barrill spent 12 days in total on the attempt, and claimed to have reached the summit via the Ruth Glacier.

Upon hearing Cook's claims, Parker and Browne were immediately suspicious. Browne later wrote that he knew Cook's claims were lies, just as "any New Yorker would know that no man could walk from the Brooklyn Bridge to Grant's Tomb [a distance of eight miles] in ten minutes." In May 1907, Harper's Magazine published Cook's account of the climb along with a photograph of what appeared to be Barrill standing on the summit. By 1909, Barrill had recanted at least part of his story about the climb, and others publicly questioned the account; however, Cook continued to assert his claim.{{Cite web|url=https://library.osu.edu/projects/frederick-cook/controversy.html|title=Controversy - Frederick A.

Washburn noted inconsistencies between Cook's account of locations of glaciers and found a spot, at {{convert|5400|ft|m|0|abbr=out}} and {{convert|19|mi|0|abbr=out}} southeast of the summit that appeared identical to the supposed summit image. Gonnason was not able to complete the climb, but because he was turned back by poor weather, felt that this did not definitely disprove Cook's story.{{Cite magazine|url=https://time.com/4017660/mount-mckinley-denali-ascent-hoax/|archive-url=https://web.archive.org/web/20150902135911/http://time.com/4017660/mount-mckinley-denali-ascent-hoax/|archive-date=September 2, 2015|title=The Other Mount McKinley Controversy: Who Climbed Denali First|last=Berman|first=Eliza|magazine=Time|access-date=October 31, 2019}} In 1998, historian Robert Bryce discovered an original and un-cropped version of the "fake peak" photograph of Barrill standing on the promontory.

Given the skepticism concerning Cook's story, interest in claiming the first ascent remained. Miners and other Alaskans living in Kantishna and Fairbanks wanted the honors to go to local men. In 1909, four Alaska residents – Tom Lloyd, Peter Anderson, Billy Taylor, and Charles McGonagall – set out from Fairbanks, Alaska during late December with supplies and dogs that were in part paid for by bettors in a Fairbanks tavern. By March 1910, the men had established a base camp near one of the sites where the Brooks party had been and pressed on from the north via the Muldrow glacier. Unlike some previous expeditions, they discovered a pass, since named McGonagall Pass, which allowed them to bypass the Wickersham Wall and access the higher reaches of the mountain. At roughly {{convert|11,000|ft|m|0|abbr=out}}, Tom Lloyd, old and less physically fit than the others, stayed behind. According to their account, the remaining three men pioneered a route following Karstens Ridge around the Harper Icefall, then reached the upper basin before ascending to Pioneer Ridge. The three men carried a {{convert|14|ft|m|adj=mid|-long}} spruce pole. Around {{convert|19,000|ft|m|0|abbr=out}}, Charles McGonagall, older and having exhausted himself carrying the spruce pole, remained behind. On April 3, 1910, Billy Taylor and Peter Anderson scrambled the final few hundred feet to reach the north peak of Denali, at {{convert|19,470|ft|m|0|abbr=out}} high, the shorter of the two peaks. The pair erected the pole near the top, with the hope that it would be visible from lower reaches to prove they had made it.{{Cite web|title=Denali NP: Historic Resource Study (Chapter 3)|url=https://www.nps.gov/parkhistory/online_books/dena/hrs3a.htm|access-date=July 5, 2020|publisher=National Park Service|archive-date=October 1, 2020|archive-url=https://web.archive.org/web/20201001083905/https://www.nps.gov/parkhistory/online_books/dena/hrs3a.htm|url-status=live}}

After the expedition, Tom Lloyd returned to Fairbanks, while the three others remained in Kantishna to mine. In Lloyd's recounting, all four men made it to the top of not only the north peak, but the higher south peak as well. When the remaining three men returned to town with conflicting accounts, the entire expedition's legitimacy was questioned.{{Cite web|date=June 8, 2019|title=Did they make it or fake it?

However, some continue to doubt they reached the summit. Outside of the single later climbing group, who were friendly with some of the Sourdough expedition men, no other group would ever see it. Jon Waterman, author of the book Chasing Denali, which explored the controversy, outlined several reasons to doubt the claim: There was never any photographic evidence. The four men climbed during the winter season, known for much more difficult conditions, along a route that has never been fully replicated. They were inexperienced climbers, ascending without any of the usual safety gear or any care for altitude sickness. They claimed to have ascended from {{convert|11,000|ft|m|0|abbr=out}} to the top in less than 18 hours, unheard of at a time when siege-style alpinism was the norm.{{Cite web|title=Chasing Denali – A Story of the Most Unbelievable Feat in Mountaineering|url=https://rockandice.com/climbing-destinations/chasing-denali-a-story-of-the-most-unbelievable-feat-in-mountaineering/|access-date=July 5, 2020|website=Rock and Ice|date=November 2018|archive-date=September 20, 2020|archive-url=https://web.archive.org/web/20200920063757/https://rockandice.com/climbing-destinations/chasing-denali-a-story-of-the-most-unbelievable-feat-in-mountaineering/|url-status=live}} Yet Waterman says "these guys were men of the trail.

In 1912, the Parker-Browne expedition nearly reached the summit, turning back within just a few hundred yards/meters of it due to harsh weather. On July 7, the day after their descent, a 7.4-magnitude earthquake shattered the glacier they had ascended.{{cite web|title=North peak of Mount McKinley: A Timely Escape |url=http://explore.americanalpineclub.org/index.php/Detail/Object/Show/object_id/5369 |publisher=The American Alpine Club |access-date=October 5, 2015 |archive-url=https://web.archive.org/web/20150906153300/http://explore.americanalpineclub.org/index.php/Detail/Object/Show/object_id/5369 |archive-date=September 6, 2015 }}{{cite book|last1=Heacox|first1=Kim|title=Rhythm of the Wild: A Life Inspired by Alaska's Denali National Park|date=2015|publisher=Rowman & Littlefield|location=Connecticut|isbn=978-1-4930-0389-1|pages=55–56|url=https://books.google.com/books?id=rmQlCQAAQBAJ&pg=PR4|access-date=June 17, 2019|archive-date=July 9, 2024|archive-url=https://web.archive.org/web/20240709190527/https://books.google.com/books?id=rmQlCQAAQBAJ&pg=PR4#v=onepage&q&f=false|url-status=live}}{{cite book | last1 =Stover | first1 =Carl W. | last2 =Coffman | first2 =Jerry L. | title =Seismicity of the United States, 1568–1989 | edition =revised | publisher =United States Government Printing Office | date =1993 | page =52 | url =https://books.google.com/books?id=bY0KAQAAIAAJ&q=alaska+earthquake+july+7,+1912 | quote =This earthquake was violent at Fairbanks and strong at Kennicott.

The first ascent of the main summit of Denali came on June 7, 1913, by a party directed by Hudson Stuck and Harry Karstens, along with Walter Harper and Robert Tatum. Karstens relocated to Alaska in the gold rush of 1897, and in subsequent years became involved in a variety of endeavors beyond mining, including helping establish dog mushing routes to deliver mail across vast swathes of territory and supporting expeditions led by naturalist Charles Sheldon near the base of Denali.{{Cite web|title=Superintendent Harry Karstens|publisher=National Park Service|url=https://www.nps.gov/dena/learn/photosmultimedia/station06a.htm|access-date=July 7, 2020|archive-date=July 7, 2020|archive-url=https://web.archive.org/web/20200707134122/https://www.nps.gov/dena/learn/photosmultimedia/station06a.htm|url-status=live}} Stuck was an English-born Episcopal priest who came to Alaska by chance. He became acclimated to the often harsh Alaskan environment because of his many travels between far-flung outposts within his district, climbing mountains as a hobby.{{Cite web |title=Who Led the First Ascent of Denali? |first=Christine |last=Woodside |date=June 6, 2012 |url=https://chriswoodside.com/who-led-the-first-ascent-of-denali/ |access-date=July 7, 2020 |archive-date=July 9, 2024 |archive-url=https://web.archive.org/web/20240709192652/https://chriswoodside.com/who-led-the-first-ascent-of-denali/ |url-status=live }} At 21 years old, Harper was already known as a skilled and strong outdoorsman, the Alaska-born son of a Koyukon-Athabascan mother and Irish gold prospector father.{{Cite web|title=The Ultimate Triumph and Tragedy: Remembering Walter Harper 100 Years Later|publisher=National Park Service|url=https://www.nps.gov/articles/dena-history-harper.htm|access-date=July 7, 2020|archive-date=July 9, 2024|archive-url=https://web.archive.org/web/20240709192610/https://www.nps.gov/articles/dena-history-harper.htm|url-status=live}}{{Cite magazine |title=Denali, A Universe |first=Jan |last=Harper-Haines |url=http://www.alpinist.com/doc/web19f/wfeature-a67-wired-denali-universe |access-date=July 7, 2020 |magazine=Alpinist |archive-date=August 1, 2020 |archive-url=https://web.archive.org/web/20200801052346/http://www.alpinist.com/doc/web19f/wfeature-a67-wired-denali-universe |url-status=live }} Tatum, also 21 years old, was a theology student working at a Tanana mission, and the least experienced of the team. His primary responsibility on the trip was as a cook.{{Cite book|last=Ehrlander|first=Mary|title=Walter Harper, Alaska Native Son|publisher=University of Nebraska Press|year=2017|page=55}}

The team approached the peak from the north via the Muldrow glacier and McGonagall pass. While ferrying loads up to a camp at around {{convert|10,800|ft|m|0|abbr=out}}, they suffered a setback when a stray match accidentally set fire to some supplies, including several tents. The prior year's earthquake had left what had previously been described by the Parker-Browne expedition as a gentle slope ascended in no more than three days as a dangerous, ice-strewn morass on a knife-edged ridge (later named Karstens ridge). It would take the team three weeks to cover the same ground, as Karstens and Harper laboriously cut steps into the ice. On May 30, the team, with the help of some good weather, ascended to a new high camp, situated at {{convert|17,500|ft|m|0|abbr=out}} in the Grand Basin between the north and south peaks. On June 7, the team made the summit attempt. Temperatures were below {{convert|-20|°F|°C}} at times. Every man, and particularly Stuck, suffered from altitude sickness. By midday, Harper became the first climber to reach the summit, followed seconds later by Tatum and Karstens. Stuck arrived last, falling unconscious on the summit.{{Cite web |title=A Brief Account of the 1913 Climb of Denali |publisher=National Park Service |url=https://www.nps.gov/dena/learn/historyculture/1913ex.htm |access-date=July 7, 2020 |archive-date=July 7, 2020 |archive-url=https://web.archive.org/web/20200707024044/https://www.nps.gov/dena/learn/historyculture/1913ex.htm |url-status=live }}

Using the mountain's contemporary name, Tatum later commented, "The view from the top of Mount McKinley is like looking out the windows of Heaven!"{{sfn|Coombs|Washburn|1997|p=26}} During the climb, Stuck spotted, via binoculars, the presence of a large pole near the North Summit; this report confirmed the Sourdough ascent, and it is widely believed presently that the Sourdoughs did succeed on the North Summit. However, the pole was never seen before or since, so there is still some doubt. Stuck also discovered that the Parker-Browne party were only about {{convert|200|ft|m|0|abbr=out}} of elevation short of the true summit when they turned back. Stuck and Karstens' team achieved the uncontroversial first ascent of Denali's south peak; however, the news was met with muted interest by the wider climbing community. Appalachia Journal, then the official journal of the American Alpine Club, published a small notice of the accomplishment a year later.

The mountain is climbed regularly nowadays. In 2003, around 58% of climbers reached the top. But by that time, the mountain had claimed the lives of nearly 100 mountaineers.{{cite news | last = Glickman | first = Joe | url = https://www.nytimes.com/2003/08/24/travel/man-against-the-great-one.html?pagewanted=all | title = Man Against the Great One | work = The New York Times | date = August 24, 2003 | access-date = September 25, 2010 | archive-date = May 18, 2013 | archive-url = https://web.archive.org/web/20130518170229/http://www.nytimes.com/2003/08/24/travel/man-against-the-great-one.html?pagewanted=all | url-status = live }} The vast majority of climbers use the West Buttress Route, pioneered in 1951 by Bradford Washburn,{{cite journal|last=Roberts |first=David |title=The Geography of Brad Washburn (1910–2007) |journal=National Geographic Adventure |date=April 2007 |url=http://www.nationalgeographic.com/adventure/mountaineering/bradford-washburn.html |access-date=March 4, 2013 |archive-url=https://web.archive.org/web/20131103231812/http://www.nationalgeographic.com/adventure/mountaineering/bradford-washburn.html |archive-date=November 3, 2013 }} after an extensive aerial photographic analysis of the mountain. Climbers typically take two to four weeks to ascend Denali. It is one of the Seven Summits; summiting all of them is a challenge for mountaineers.

Weather station

File:Mount McKinley and Denali National Park Road 2048px.jpg

The Japanese Alpine Club installed a meteorological station on a ridge near the summit of Denali at an elevation of {{convert|18733|ft}} in 1990.{{cite web|last=Rozell|first=Ned|title=Mountaineering and Science Meet on Mt.

In June 2002, a weather station was placed at the {{convert|19000|ft|m|adj=on}} level. This weather station was designed to transmit data in real-time for use by the climbing public and the science community. Since its establishment, annual upgrades to the equipment have been performed with instrumentation custom built for the extreme weather and altitude conditions. This weather station is the third-highest weather station in the world.{{cite news|title=Japanese install probe on tallest US peak |url=http://info.japantimes.co.jp/text/nn20060717f2.html |access-date=January 24, 2013 |newspaper=The Japan Times |date=July 17, 2006 |archive-url=https://web.archive.org/web/20131103213828/http://info.japantimes.co.jp/text/nn20060717f2.html |archive-date=November 3, 2013 }}

The weather station recorded a temperature of {{convert|-75.5|°F|°C|abbr=on}} on December 1, 2003. On the previous day of November 30, 2003, a temperature of {{convert|-74.4|°F|°C|abbr=on}} combined with a wind speed of {{convert|18.4|mph}} to produce a North American record windchill of {{convert|-118.1|°F|°C|abbr=on}}.

Even in July, this weather station has recorded temperatures as low as {{convert|-22.9|°F|°C|abbr=on}} and windchills as low as {{convert|-59.2|°F|°C|abbr=on}}.

=Historical record=

According to the National Park Service, in 1932 the {{Not a typo|Liek}}-Lindley expedition recovered a self-recording minimum thermometer left near Browne's Tower, at about {{convert|15000|ft|sigfig=2}}, on Denali by the Stuck-Karstens party in 1913. The spirit thermometer was calibrated down to {{convert|-95|°F|°C|abbr=on}}, and the lowest recorded temperature was below that point. Harry J. Liek took the thermometer back to Washington, D.C. where it was tested by the United States Weather Bureau and found to be accurate. The lowest temperature that it had recorded was found to be approximately {{convert|-100|F|C}}.{{cite book|last=Dixon|first=Joseph S.|title=Fauna of the National Parks of the United States|year=1938|publisher=National Park Service|location=Washington, D.C.|url=http://www.cr.nps.gov/history/online_books/fauna3/fauna2.htm|access-date=January 24, 2013|archive-date=November 4, 2012|archive-url=https://web.archive.org/web/20121104034509/http://www.cr.nps.gov/history/online_books/fauna3/fauna2.htm|url-status=dead}} Another thermometer was placed at the {{convert|15000|ft|sigfig=2|adj=on}} level by the U.S. Army Natick Laboratory, and was there from 1950 to 1969. The lowest temperature recorded during that period was also {{convert|-100|°F|°C}}.{{Cite web |url=http://www.wunderground.com/blog/weatherhistorian/the-coldest-places-on-earth |title=Wunderground.com – Weather Extremes: The Coldest Places On Earth |access-date=April 29, 2019 |archive-date=April 16, 2017 |archive-url=https://web.archive.org/web/20170416125749/https://www.wunderground.com/blog/weatherhistorian/the-coldest-places-on-earth }}
