Denali is the highest mountain peak in North America.

It is located within the Alaska Range in the interior of Alaska. The mountain serves as the centerpiece of Denali National Park and Preserve. It is notable for being the tallest mountain on Earth from base to peak on land. This measurement is approximately 18,000 feet.

While Mount Everest has a higher summit, its base sits much higher on the Tibetan Plateau. Denali rises from a sloping plain that starts at only 2,000 feet. This gives it a massive base-to-peak rise. It is the third most prominent and third-most isolated peak on our planet.

The mountain is a granitic pluton. This means it is a large mass of igneous rock formed deep underground. It consists mostly of pink quartz monzonite. Tectonic pressure created this mountain. This pressure comes from the subduction of the Pacific plate beneath the North American plate. Subduction is when one tectonic plate slides under another. As the plates move, the rock is lifted upward. At the same time, erosion stripped away the sedimentary material that once sat above it. This tectonic activity also causes deep earthquakes in Alaska and the Aleutian Islands. The region under the mountain is known as the McKinley cluster.

Complex structural geology also shapes the high topography of the mountain. The Denali Fault and the Denali Fault Bend are key features. The Denali Fault is caused by the low-angle subduction of the Yakutat microplate. The Denali Fault Bend is a gentle restraining bend in the fault. This bend is approximately 75 km long. This curvature creates a "space problem" for the moving crust. As the fault moves, high compressional forces push the crust upward vertically. The longer the crust stays in this bend, the higher the mountain becomes. Some active normal faults north of this bend move at rates of 2 to 6 mm per year.

Denali has two significant summits. The South Summit is the higher of the two. The North Summit has an elevation of 18,190 feet. It has a topographic prominence of about 1,500 feet. Some people count the North Summit as a separate peak. However, it is rarely climbed by mountaineers. The mountain is also home to five large glaciers. These include the Peters, Muldrow, Traleika, and Ruth glaciers.

The Kahiltna Glacier leads up the southwest side. At 49 miles long, it is the longest glacier in the Alaska Range.

The history of climbing Denali includes many attempts. James Wickersham recorded the first attempt in 1903, but it failed. In 1906, Frederick Cook claimed he reached the summit. However, his claim is unverified and many people question its legitimacy. The first verifiable ascent occurred on June 7, 1913. The team included Hudson Stuck, Harry Karstens, Walter Harper, and Robert Tatum. They reached the top via the South Summit.

In 1951, Bradford Washburn pioneered the West Buttress route. This route is now the most popular and safest way to climb.

Naming the mountain has been a subject of much debate. For centuries, the Koyukon people called it Denali. In their language, the name means "the tall one." Other indigenous groups use names meaning "big mountain."

In 1896, a gold prospector named it Mount McKinley. He did this to support William McKinley, a presidential candidate. The federal government used the name Mount McKinley from 1917 until 2015. In August 2015, the Department of the Interior changed the official name back to Denali. This was done to match the name used by the state of Alaska. However, in January 2025, the name was changed back to Mount McKinley by executive order.

These name changes involve complex legal and political processes. The change in 2015 faced criticism from some politicians in Ohio. They argued that only Congress had the power to rename the mountain. However, the Secretary of the Interior argued they had the authority. This authority exists when the Board on Geographic Names does not act within a reasonable time. In 2025, the federal government reverted the name to Mount McKinley. This change applies to official maps and communications. It does not change the name of Denali National Park. The mountain remains a vital part of Alaskan identity and global geography.
