A GIANT AMONG GIANTS: DENALI’S IMPRESSIVE STATISTICS

Denali (also known as Mount McKinley, its former official name) 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.

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.

Denali, the crown jewel of Alaska’s wilderness, stands as a colossal testament to the raw power of tectonic forces. While its official height of 20,310 feet (6,190 meters) is impressive, it’s the mountain’s other dimensions that truly set it apart. Denali boasts a base-to-peak rise of about 18,000 feet (5,500 meters), surpassing even Mount Everest’s 12,000-foot rise from its base on the Tibetan Plateau. This staggering vertical relief contributes to Denali’s reputation as one of the most challenging climbs in the world.

THE WEATHER STATION: DENALI’S EXTREME CLIMATE

Denali’s severe Arctic climate is legendary among mountaineers. The mountain creates its own weather systems, with temperatures plummeting as low as -75°F (-59°C) and wind speeds reaching hurricane force. The combination of high latitude and extreme elevation results in an atmospheric pressure at the summit that’s only about 42% of sea level pressure, making the physiological altitude (how high it feels to your body) closer to 23,000 feet (7,000 meters).

A GEOLOGICAL MARVEL: THE MOUNTAIN THAT’S STILL GROWING

Fascinatingly, Denali is still growing. Tectonic activity pushes the mountain upward at a rate of about 1 millimeter per year. This ongoing geological process ensures that Denali remains a dynamic and ever-changing challenge for climbers and scientists alike.

THE CHALLENGE OF THE WEST BUTTRESS

For mountaineers, the West Buttress route has become the standard path to the summit, first pioneered by Bradford Washburn in 1951. This route, while considered the „easiest” way up Denali, still presents formidable challenges. Climbers must navigate vast crevasse fields, endure prolonged exposure to extreme cold, and battle the mountain’s notoriously fickle weather.

DENALI’S UNIQUE FLORA AND FAUNA

Despite its harsh environment, Denali supports a surprising array of life. The mountain and its surrounding areas are home to over 1,500 species of vascular plants, lichens, and mosses. Wildlife enthusiasts might spot Dall sheep, grizzly bears, and even wolves at lower elevations. The highest recorded bird sighting on Denali was a Northern Raven observed at 20,320 feet, demonstrating the incredible adaptability of some species to extreme conditions.

THE MOUNTAIN OF GREAT BREATH

In the language of the Koyukon Athabascans, „Denali” means „the high one” or „the great one.” However, some linguists suggest it could also be translated as „the mountain of great breath,” alluding to the extreme difficulty in breathing experienced by climbers at high altitudes due to the thin air.

DENALI’S IMPACT ON CLIMATE RESEARCH

Denali’s massive glaciers serve as crucial indicators of climate change. The Kahiltna Glacier, the longest glacier in the Alaska Range at 44 miles (71 km), has been the subject of extensive scientific study. Researchers use ice cores from Denali’s glaciers to unlock secrets about Earth’s climate history, making the mountain an invaluable resource for understanding global climate patterns.
