The Koyukon Athabaskan people who inhabit the area around the mountain refer to the peak as Dinale or Denali. The name is based on a Koyukon word for "high" or "tall".[18] 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.[19] It was briefly called Densmore's Mountain in the late 1880s and early 1890s[20] after Frank Densmore, an Alaskan prospector who was the first European to reach the base of the mountain.
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.[22] The Alaska Board of Geographic Names changed the name of the mountain to Denali, which is how it is referred to locally.
