On June 7, 1913, Hudson Stuck, an Alaskan missionary, leads the first successful ascent of Denali (formerly known as Mt. McKinley) the highest point on the American continent at 20,320 feet.

Stuck, an accomplished amateur mountaineer, was born in London in 1863. After moving to the United States, in 1905 he became archdeacon of the Episcopal Church in Yukon, Alaska, where he was an admirer of Native Indian culture and traveled Alaska’s difficult terrain to preach to villagers and establish schools.

In March 1913, the adventure-seeking Stuck set out from Fairbanks for Denali with three companions, Harry Karstens, co-leader of the expedition, Walter Harper, whose mother was a Native Indian, and Robert Tatum, a theology student. Their arduous journey was made more challenging by difficult weather and a fire at one of their camps, which destroyed food and supplies. However, the group persevered and on June 7, Harper, followed by the rest of the party, was the first person to set foot on Denali's south peak, considered the mountain’s true summit. (In 1910, a group of climbers had reached the lower north peak.)

Stuck referred to the mountain by its Athabascan Indian name, Denali, meaning “The High One.” In 1889, the mountain, over half of which is covered with permanent snowfields, was dubbed Densmores Peak, after a prospector named Frank Densmore. In 1896, it was renamed in honor of Senator William McKinley, who became president that year.

Mount McKinley National Park was established as a wildlife refuge in 1917. Harry Karstens served as the park’s first superintendent. In 1980, the park was expanded and renamed Denali National Park and Preserve. Encompassing 6 million acres, the park is larger than Massachusetts. In 2015, the mountain was officially renamed Denali.

Hudson Stuck died in Alaska on October 10, 1920. Today, over 1,000 hopeful climbers attempt to scale Denali each year, with about half of them successfully reaching their goal.
