- Denali is the highest mountain in North America, the United States, and Alaska. Denali, with 20,156 feet (6,144 meters) of prominence, is the third most prominent mountain in the world, with only Mount Everest and Aconcagua having more prominence. Denali is one of the Seven Summits and is an ultra-prominent peak with more than 5,000 feet of prominence.
- Denali AKA Mount McKinley has a vertical relief of 18,000 feet, greater than Mount Everest, when measured from the 2,000-foot lowlands at its base to its 20,320-foot summit. Everest’s vertical rise is about 12,000 feet. Denali rises about 18,000 feet (5,500 meters) from its base, which is a 2,000-foot-high (610-meter) plateau. This is a greater vertical rise than Mount Everest’s 12,000-foot (3,700-meter) rise from its base at 17,000 feet (5,200 meters).
- Denali offers brutally cold and extreme weather conditions to climbers year-round. Temperatures dip as low as -75° F (-60° C) with windchill temperatures down to -118° F (-83° C), cold enough to flash freeze a human. These temperatures have been recorded at the automated Mount McKinley Weather Station at 18,700 feet (5,700 meters).
- Because of its far northern latitude of 63°, Denali has lower barometric pressure than other high mountains in the world, affecting the acclimatization of climbers. The lower barometric pressure is because the troposphere is thinner near the poles and thicker at the equator. Likewise, Denali has less oxygen on its summit than mountains close to the equator. Denali’s summit oxygen is 42% of the oxygen at sea level, whereas a mountain close to the equator has 47% of sea-level oxygen at an equivalent elevation.
- Denali, meaning “The High One,” is the native Athabascan name for North America’s highest mountain. It was renamed Mount McKinley for then-presidential nominee William McKinley by prospector William Dickey during the 1896 Cook Inlet gold rush. Dickey named the peak because McKinley championed the gold standard rather than silver .
- The state of Alaska changed the name of Mount McKinley to Denali in 1975. The Alaska Geographic Names Board maintains that Denali is the proper name for the mountain, while the federal Board of Geographic Names continues to uphold the name McKinley. The name of Mount McKinley National Park was changed to Denali National Park and Preserve in 1980. Alaskans and climbers call the mountain Denali.
- The first serious attempt to climb Denali was in 1910 when two Alaskan prospectors—Peter Anderson and Billy Taylor—from a party of four reached the summit of the lower 19,470-feet North Summit on April 3. They climbed 8,000 feet from their 11,000-foot camp to the summit and returned to camp in 18 hours—an astonishing feat! The crew, called the Sourdough Expedition, were climbing novices who spent 3 months climbing to win a bet with a bar owner who said it would never be climbed. They wore homemade crampons, snowshoes, Inuit mukluks, overalls, parkas, and mittens. On summit day, they carried doughnuts, caribou meat, 3 flasks of hot drinks, and a 14-foot-long spruce pole and an American flag. Their hope was that someone with a telescope would see the pole and flag and know that the peak had been climbed. After returning to Kantishna, the climbers were welcomed as heroes. Skeptics wouldn’t accept that the greenhorns had summitted Denali. The 1913 South Summit first ascent party, however, saw the flagpole, vindicating the extraordinary ascent.
- The first ascent of the main or South Summit of Denali was on June 7, 1913 by Walter Harper, Harry Karstens, and Robert Tatum from an expedition led by Hudson Stuck. They climbed the Muldrow Glacier route. Stuck saw the flagpole planted by the Sourdough climbers with binoculars on the North Summit, confirming their success.
- The usual number of climbers on Denali each year is 1,275. The most in one season was 1,305 in 2001. The number of climbers who reach Denali’s summit is 656 with an average of 51% of annual climbers reaching the summit. The average number of rescues is 14 and the mountain averages one fatality a year.
- In the 2010 climbing season, 1,222 climbers in 281 teams attempted Denali by 11 different routes. A total of 670 climbers or 55% reached the summit. Most climbers—1,135—attempted the West Buttress, with 630 or 56% topping out. The average trip length for a successful ascent was 18.3 days. June was the busiest month with 370 ascents, followed by May with 226 and July with 74. The average climber age was 38.1 years. Most climbers were from the United States with 673, followed by the United Kingdom with 62 and Canada with 52. Most American climbers came from Alaska (146), Washington (90), and Colorado (83).
- The deadliest climbing season on Denali was May, 1992 when 11 climbers in 5 parties died. Other deadly seasons were 1967 and 1980 when 8 climbers died and 1981 and 1989 when 6 climbers died.
