Denali

Denali (/dɪˈnɑːli/)[5][6] (also known as Mount McKinley, its former official name)[7] is the highest mountain peak in North America, with a summit elevation of 20,310 feet (6,190 m) 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 on Earth, 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 Federal government of the United States from 1917 until 2015. In August 2015, following the 1975 lead of the State of Alaska, the United States Department of the Interior announced the change of the official name of the mountain to Denali.[8][9]

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.[10]

On September 2, 2015, the U.S. Geological Survey announced that the mountain is 20,310 feet (6,190 m) high,[1] not 20,320 feet (6,194 m), 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.[11] 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".[12]

Denali has a summit elevation of 20,310 feet (6,190 m) above sea level, making it the highest peak in North America and the northernmost mountain above 6,000 meters elevation in the world.[1] Measured from base to peak at some 18,000 ft (5,500 m), it is among the largest mountains situated entirely above sea level. Denali rises from a sloping plain with elevations from 1,000 to 3,000 ft (300 to 910 m), for a base-to-peak height of 17,000 to 19,000 ft (5,000 to 6,000 m).[13] By comparison, Mount Everest rises from the Tibetan Plateau at a much higher base elevation. Base elevations for Everest range from 13,800 ft (4,200 m) on the south side to 17,100 ft (5,200 m) on the Tibetan Plateau, for a base-to-peak height in the range of 12,000 to 15,300 ft (3,700 to 4,700 m).[14] Denali's base-to-peak height is little more than half the 33,500 ft (10,200 m) of the volcano Mauna Kea, which lies mostly under water.[15]

Geography of the mountain

Denali has two significant summits: the South Summit is the higher one, while the North Summit has an elevation of 19,470 ft (5,934 m)[11] and a prominence of approximately 1,270 ft (387 m).[16] 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.[17][18] With a length of 44 mi (71 km), the Kahiltna Glacier is the longest glacier in the Alaska Range.

Naming

The Koyukon Athabaskans who inhabit the area around the mountain have for centuries referred to the peak as Dinale or Denali. The name is based on a Koyukon word for "high" or "tall".[19] During the Russian ownership of Alaska, the common name for the mountain was Bolshaya Gora (Russian: Большая Гора, bolshaya = Russian for big; gora = Russian for mountain), which is the Russian translation of Denali.[20] It was briefly called Densmore's Mountain in the late 1880s and early 1890s[21] after Frank Densmore, an Alaskan prospector who was the first European to reach the base of the mountain.[22]

In 1896, a gold prospector named it McKinley as political support for then-presidential candidate William McKinley, who became president the following year. The United States formally recognized the name Mount McKinley after President Wilson signed the Mount McKinley National Park Act of February 26, 1917.[23] In 1965, Lyndon B. Johnson declared the north and south peaks of the mountain the "Churchill Peaks", in honor of British statesman Winston Churchill.[24] The Alaska Board of Geographic Names changed the name of the mountain to Denali in 1975, which was how it is called locally.[7][25] However, a request in 1975 from the Alaska state legislature to the United States Board on Geographic Names to do the same at the federal level was blocked by Ohio congressman Ralph Regula, whose district included McKinley's hometown of Canton.[26]

On August 30, 2015, just ahead of a presidential visit to Alaska, the Barack Obama administration announced the name Denali would be restored in line with the Alaska Geographic Board's designation.[9][27] U.S. Secretary of the Interior Sally Jewell issued the order changing the name to Denali on August 28, 2015, effective immediately.[8] Jewell said the change had been "a long time coming".[28] The renaming of the mountain received praise from Alaska's senior U.S. senator, Lisa Murkowski,[29] who had previously introduced legislation to accomplish the name change,[30] but it drew criticism from several politicians from President McKinley's home state of Ohio, such as Governor John Kasich, U.S. Senator Rob Portman, U.S. House Speaker John Boehner, and Representative Bob Gibbs, who described Obama's action as "constitutional overreach" because he said an act of Congress is required to rename the mountain.[31][32][33] The Alaska Dispatch News reported that the Secretary of the Interior has authority under federal law to change geographic names when the Board of Geographic Names does not act on a naming request within a "reasonable" period of time. Jewell told the Alaska Dispatch News that "I think any of us would think that 40 years is an unreasonable amount of time."[34]

Indigenous names for Denali can be found in seven different Alaskan languages.[35] The names fall into two categories. To the south of the Alaska Range in the Dena'ina and Ahtna languages the mountain is known by names that are translated as "big mountain". To the north of the Alaska Range in the Lower Tanana, Koyukon, Upper Kuskokwim, Holikachuk, and Deg Xinag languages the mountain is known by names that are translated as "the high one",[36] "the tall one" (Koyukon, Lower and Middle Tanana, Upper Kuskokwim, Deg Xinag, and Holikachuk), or "big mountain" (Ahtna and Dena'ina).[37] Asked about the importance of the mountain and its name, Will Mayo, former president of the Tanana Chiefs Conference, an organization that represents 42 Athabaskan tribes in the Alaskan interior, said "It’s not one homogeneous belief structure around the mountain, but we all agree that we’re all deeply gratified by the acknowledgment of the importance of Denali to Alaska’s people."[38]

History

Stuck.Karstens
Hudson Stuck and Harry Karstens, co-leaders of the first successful summit of Denali in 1913

The Koyukon Athabaskans, living in the Yukon, Tanana and Kuskokwim basins, were the first Native Americans with access to the flanks of the mountain.[4] A British naval captain and explorer, George Vancouver, is the first European on record to have sighted Denali, when he noted "distant stupendous mountains" while surveying the Knik Arm of the Cook Inlet on May 6, 1794.[39] The Russian explorer Lavrenty Zagoskin explored the Tanana and Kuskokwim rivers in 1843 and 1844, and was likely the first European to sight the mountain from the other side.[40]

William Dickey, a New Hampshire-born resident of Seattle, Washington who had been digging for gold in the sands of the Susitna River, wrote, after his returning from Alaska, an account in the New York Sun that appeared on January 24, 1897.[41] His report drew attention with the sentence "We have no doubt that this peak is the highest in North America, and estimate that it is over 20,000 feet (6,100 m) high." Until then, Mount Logan in Canada's Yukon Territory was believed to be the continent’s highest point. Though later praised for his estimate, Dickey admitted that other prospector parties had also guessed the mountain to be over 20,000 feet (6,100 m).[42]

Climbing history

The first recorded attempt to climb Denali was by Judge James Wickersham in 1903, via the Peters Glacier and the North Face, now known as the Wickersham Wall. Because of the route's history of avalanche danger, it was not successfully climbed until 1963.[44]

Famed explorer Dr. Frederick Cook claimed the first ascent of the mountain in 1906. His claim was regarded with some suspicion from the start, but was also widely believed. It was later proved false, with some crucial evidence provided by Bradford Washburn when he was sketched on a lower peak.

In 1910, four area locals – Tom Lloyd, Peter Anderson, Billy Taylor, and Charles McGonagall – known as the Sourdough Expedition, attempted to climb Denali despite a lack of climbing experience. The group spent approximately three months on the mountain. Their purported summit ascent day included carrying a bag of doughnuts each, a thermos of hot chocolate, and a 14-foot (4.2 m) spruce pole. Two of them reached the North Summit, the lower of the two, and erected the pole near the top. According to the group, the time they took to reach the summit was a total of 18 hours. Until the first ascent in 1913, their claims were disbelieved, in part due to false claims they had climbed both summits.

In 1912, the Parker-Browne expedition nearly reached the summit, turning back within just a few hundred yards of it due to harsh weather. The day after their descent, the Great Earthquake of 1912 shattered the glacier they had ascended.[45][46]

The first ascent of the main summit of Denali came on June 7, 1913, by a party led by Hudson Stuck and Harry Karstens. The first man to reach the summit was Walter Harper, an Alaska Native. Robert Tatum also made the summit. 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!"[47] They ascended the Muldrow Glacier route pioneered by the earlier expeditions, which is still often climbed today. Stuck confirmed, via binoculars, the presence of a large pole near the North Summit; this report confirmed the Sourdough ascent, and today it is widely believed 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 200 feet (61 m) of elevation short of the true summit when they turned back.

In 1990, Russian high altitude mountaineer Anatoli Boukreev completed a solo speed ascent in ten and one half hours from base camp to the summit via the west rib.[48]

The mountain is regularly climbed today. In 2003, around 58% of climbers reached the top. But by 2003, the mountain had claimed the lives of nearly 100 mountaineers over time.[49] The vast majority of climbers use the West Buttress Route, pioneered in 1951 by Bradford Washburn,[10] 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.

On August 4, 2018, 5 people died in the K2 Aviation de Havilland Beaver (DHC-2) crash near Denali.

  • 1997: First successful ascent up the West Fork of Traleika Glacier up to Karstens Ridge beneath Browne Tower. This path was named the "Butte Direct" by the two climbers Jim Wilson and Jim Blow.[71][72]
  • 2015: On June 24, a survey team led by Blaine Horner placed two global positioning receivers on the summit to determine the precise position and elevation of the summit. The summit snow depth was measured at 15 ft (4.6 m). The United States National Geodetic Survey later determined the summit elevation to be 20,310 ft (6,190 metres).[1]

Weather station

The east side viewed from Denali National Park and Preserve, which surrounds the mountain

The Japan Alpine Club installed a meteorological station on a ridge near the summit of Denali at an altitude of 18,733 feet (5,710 m) in 1990.[73] In 1998, this weather station was donated to the International Arctic Research Center at the University of Alaska Fairbanks.[73] In June 2002, a weather station was placed at the 19,000-foot (5,800 m) 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.[74]

The weather station recorded a temperature of −75.5 °F (−59.7 °C) on December 1, 2003. On the previous day of November 30, 2003, a temperature of −74.4 °F (−59.1 °C) combined with a wind speed of 18.4 miles per hour (29.6 km/h) to produce a North American record windchill of −118.1 °F (−83.4 °C).

Even in July, this weather station has recorded temperatures as low as −22.9 °F (−30.5 °C) and windchills as low as −59.2 °F (−50.7 °C).

Historical record

The mountain is characterized by extremely cold weather. Temperatures as low as −75.5 °F (−59.7 °C) and wind chills as low as −118.1 °F (−83.4 °C) have been recorded by an automated weather station located at 18,733 feet (5,700 m). According to the National Park Service, in 1932 the Liek-Lindley expedition recovered a self-recording minimum thermometer left near Browne's Tower, at about 15,000 feet (4,600 m), on Denali by the Stuck-Karstens party in 1913. The spirit thermometer was calibrated down to −95 °F (−71 °C), and the lowest recorded temperature was below that point. Harry J. Lek 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 −100 °F (−73 °C).[75] Another thermometer was placed at the 15,000 feet (4,600 m) level by the U.S. Army Natick Laboratory, and was there from 1950 to 1969. The coldest temperature recorded during that period was also −100 °F (−73 °C).[76]

2002 Denali earthquake

The 2002 Denali earthquake occurred at 22:12:41 UTC (1:12 PM Local Time) November 3 with an epicenter 66 km ESE of Denali National Park, Alaska, United States. This 7.9 Mw earthquake was the largest recorded in the United States in 37 years (after the 1965 Rat Islands earthquake). The shock was the strongest ever recorded in the interior of Alaska. Due to the remote location, there were no fatalities and only a few injuries.

Due to the shallow depth, it was felt at least as far away as Seattle and it generated seiches on bodies of water as far away as Texas and New Orleans, Louisiana. About 20 houseboats were damaged by a seiche on a lake in Washington State.

Alaska Range

The Alaska Range is a relatively narrow, 650-km-long (400 mi) mountain range in the southcentral region of the U.S. state of Alaska, from Lake Clark at its southwest end to the White River in Canada's Yukon Territory in the southeast. The highest mountain in North America, Denali, is in the Alaska Range. It is part of the American Cordillera.

The range is the highest in the world outside Asia and the Andes.

Cadence Design Systems

Cadence Design Systems, Inc. is an American multinational electronic design automation (EDA) software and engineering services company, founded in 1988 by the merger of SDA Systems and ECAD, Inc. The company produces software, hardware and silicon structures for designing integrated circuits, systems on chips (SoCs) and printed circuit boards.

Chevrolet Suburban

The Chevrolet Suburban is a full-size SUV from Chevrolet. It is the longest continuous use automobile nameplate in production, starting in 1935 for the 1935 U.S. model year, and has traditionally been one of General Motors' most profitable vehicles. The 1935 first generation Carryall Suburban was one of the first production all-metal bodied station wagons.In addition to the Chevrolet brand, the Suburban was produced under the GMC marque until its version was rebranded Yukon XL, and also briefly as a Holden. For most of its recent history, the Suburban has been a station wagon-bodied version of the Chevrolet pickup truck, including the Chevrolet C/K and Silverado series of truck-based vehicles. Cadillac offers a version called the Escalade ESV.

The Suburban is sold in the United States (including the insular territories), Canada, Central America, Chile, Mexico, Myanmar, Laos, Angola, the Philippines, and the Middle East (except Israel) while the Yukon XL is sold only in North America (United States and Canada) and the Middle East territories (except Israel).

Chevrolet Tahoe

The Chevrolet Tahoe (and its rebadged version the GMC Yukon) is a full-size SUV from General Motors. Chevrolet and GMC sold two different-sized SUVs under their Blazer/Jimmy model names through the early 1990s. This situation changed when GMC rebadged the full-size Jimmy as the Yukon in 1991. Chevrolet waited until 1994 to rebadge the redesigned mid-size S-10 Blazer as the Blazer, renaming the full-size Blazer as the Tahoe. The name Tahoe refers to the rugged and scenic area surrounding Lake Tahoe in the western United States. The name Yukon refers to the Yukon territory of northern Canada. For the 1995 model year, the Tahoe and Yukon gained a new 4-door model slotting in size between the 2-door models and the longer wheelbase and higher passenger capacity to up to nine passengers like the Chevrolet Suburban and newly named Yukon XL.

The Tahoe is sold in North America, Central America, the Middle East (excluding Israel), Chile, Ecuador, Myanmar, Cambodia, Laos, Angola, the Philippines, and Russia as a left-hand drive vehicle. The Yukon is only sold in North America and the Middle East (excluding Israel).

The Chevrolet Tahoe and GMC Yukon currently serve as a part of General Motors' full-size SUV family. Lengthened wheelbase models are available for both as the Suburban for Chevrolet and Yukon XL for GMC. A luxury Denali model joined the Yukon lineup in 1998 for the 1999 model year. As of 2001, a Denali version of the Yukon XL has also been available as the Yukon XL Denali. The Cadillac Escalade is closely related to the Denali models of the Yukon. As of February 2014, the 2014 Tahoe was the top-ranked Affordable Large SUV in U.S. News & World Report's rankings.The Tahoe's main competition comes from the Ford Expedition, but it also competes with the Toyota Sequoia and Nissan Armada.

The Tahoe has regularly been the best selling full-size SUV in the United States, often times outselling its competition by 2 to 1.

Denali Borough, Alaska

The Denali Borough is a borough located in the U.S. state of Alaska. As of the 2010 census the population of the borough was 1,826. The borough seat is Healy, and its only incorporated place is Anderson. The borough was incorporated in 1990.

The area was previously a part of the Unorganized Borough, with the Upper Railbelt School District serving as the region's rural education attendance area (which was replaced by a school district under the borough's umbrella upon incorporation).

Denali Fault

The Denali Fault is a major intracontinental dextral (right lateral) strike-slip fault in western North America, extending from northwestern British Columbia, Canada to the central region of the U.S. state of Alaska.

Denali National Park and Preserve

Denali National Park and Preserve is an American national park and preserve located in Interior Alaska, centered on Denali, the highest mountain in North America. The park and contiguous preserve encompass 6,045,153 acres (9,446 sq mi; 24,464 km2) which is larger than the state of New Hampshire. On December 2, 1980, 2,146,580-acre (3,354 sq mi; 8,687 km2) Denali Wilderness was established within the park. Denali's landscape is a mix of forest at the lowest elevations, including deciduous taiga, with tundra at middle elevations, and glaciers, snow, and bare rock at the highest elevations. The longest glacier is the Kahiltna Glacier. Wintertime activities include dog sledding, cross-country skiing, and snowmobiling. The park received 594,660 recreational visitors in 2018.

Denali State Park

Denali State Park is a 325,240-acre (131,620 ha) state park in the U.S. state of Alaska. It is located in the Matanuska-Susitna Borough adjacent to the east side of Denali National Park and Preserve, along the Parks Highway.

The park is undeveloped wilderness with the exception of the two day-use areas, three campgrounds, and two trailheads accessible from the Parks Highway.

George Parks Highway

The George Parks Highway (numbered Interstate A-4 and signed Alaska Route 3), usually called simply the Parks Highway, runs 323 miles (520 km) from the Glenn Highway 35 miles (56 km) north of Anchorage to Fairbanks in the Alaska Interior. The highway, originally known as the Anchorage-Fairbanks Highway, was completed in 1971, and given its current name in 1975.

The highway, which mostly parallels the Alaska Railroad, is one of the most important roads in Alaska. It is the main route between Anchorage and Fairbanks (Alaska's two largest metropolitan areas), the principal access to Denali National Park and Preserve and Denali State Park, and the main highway in the Matanuska-Susitna Valley. The route's Interstate designation is not signed; rather, its entire length is signed as Alaska Route 3.

It is a common misconception that the name "Parks Highway" comes from the road's proximity to the Denali state and national parks; it is in fact in honor of George Alexander Parks, governor of the Territory of Alaska from 1925 to 1933. However, the aptness of the name was recognized when it was chosen.

Mileposts along the Parks Highway do not begin with 0 (zero). Instead, they begin with Mile 35 (km 56), continuing the milepost numbering of the Glenn Highway where the two highways intersect near Palmer. The 0 (zero) mile marker for the Glenn Highway is at its terminus in downtown Anchorage at the intersection of East 5th Avenue and Gambell Street. Thus mileposts along the Parks Highway reflect distance from Anchorage, which is not actually on the Parks Highway.

There are two sections of the highway that are built to freeway standards. These include an area near the highway's intersection with the Glenn Highway in Palmer and a stretch known as the Robert J. Mitchell Expressway in Fairbanks leading to the highway's junction with the Richardson Highway (AK 2).

Kichatna Spire

Kichatna Spire, sometimes called the Kichatna Spires, is a 7,684-foot (2,342 m) spire-shaped peak in the Kichatna Mountains of the Alaska Range, in Denali National Park and Preserve, southwest of Denali. Cul-de-sac, Shelf and Shadows Glaciers originate at Kichatna Spire.

Mount Foraker

Mount Foraker is a 17,400-foot (5,304 m) mountain in the central Alaska Range, in Denali National Park, 14 mi (23 km) southwest of Denali. It is the second highest peak in the Alaska Range, and the third highest peak in the United States. It rises almost directly above the standard base camp for Denali, on a fork of the Kahiltna Glacier also near Mount Hunter in the Alaska Range.

Its north peak was first climbed on August 6, 1934, and its higher south peak was climbed four days later on August 10, by Charles Houston, T. Graham Brown, and Chychele Waterston, via the west ridge.

Mount Hunter (Alaska)

Mount Hunter or Begguya is a mountain in Denali National Park in Alaska. It is approximately eight miles (13 km) south of Denali, the highest peak in North America. "Begguya" means child (of Denali) in the Dena'ina language. Mount Hunter is the third-highest major peak in the Alaska Range.[1]Mount Hunter has a complex structure: it is topped by a large, low-angled glacier plateau, connecting the North (Main) Summit and the South Summit (13,965 feet or 4,257 m). Long, corniced ridges extend in various directions; between them are exceptionally steep faces.

Mount Silverthrone (Alaska)

Mount Silverthrone is a massive glaciated mountain on the east side of Denali, Alaska, United States.

Paleo-Arctic Tradition

The Paleo-Arctic Tradition is the name given by archaeologists to the cultural tradition of the earliest well-documented human occupants of the North American Arctic, which date from the period 8000–5000 BC. The tradition covers Alaska and expands far into the east, west, and the Southwest Yukon Territory.

The Upward Sun River site, a Late Pleistocene archaeological site associated with the Paleo-Arctic Tradition, located in the Tanana Valley, Alaska has now been dated to around 11,500 BP. Upward Sun River is the site of the oldest human remains discovered on the American side of Beringia.Around 8000 BC, Alaska was still connected to Siberia with the landbridge, located in the current Bering Strait. People who inhabited this region in Alaska were of the Dyuktai tradition, originally located in Siberia. Eventually, the Dyuktai changed into the Sumnagin culture, a hunting/fishing group, whose culture was defined by possessing a new technology. Other cultures flourished as well, all being placed under the general category of the Paleo-Arctic tradition.

"The Paleo-Arctic tradition is still a shadowy entity, a patchwork of local Early Holocene cultural traditions that flourished over an enormous area of extreme northwestern North America for at least 4000 years, and longer in many places. Other terms such as the Northwest Microblade tradition, Denali Complex, and Beringian tradition have been used to describe these same general adaptations, but Paleo-Arctic is the most appropriate because it is the kind of general label that reflects a great variety of different human adaptations during a period of increasing environmental diversity and change" (Fagan, p.173).The Paleo-Arctic is mostly known for lithic remains (stone technology). Some artifacts found include microblades, small wedge-shaped cores, some leaf-shaped bifaces, scrapers, and graving tools. The microblades were used as hunting weapons and were mounted in wood, antler, or bone points. Paleo-Arctic stone specialists also created bifaces that were used as tools and as cores for the production of large artifact blanks. Little evidence remains of the culture's settlement patterns, because many of the settlements were inundated by the rising sea levels of the Holocene; however, remains of stone tools were discovered, giving indirect evidence of settlement sites.

Seven Summits

The Seven Summits are the highest mountains of each of the seven continents. Climbing to the summit of all of them is regarded as a mountaineering challenge, first achieved on 30 April 1985 by Richard Bass. The Seven Summits achievement has become noted as an exploration and mountaineering accomplishment.
