Mount Barrille is a mountain summit located in the Alaska Range, in Denali National Park and Preserve, in the U.S. state of Alaska. It is situated 2,650 feet above the Ruth Glacier at the gateway to the Don Sheldon Amphitheater, or The Great Gorge, depending on direction of travel. Barrille is set southeast of Denali, west of The Mooses Tooth, east of The Rooster Comb, and north of Mount Dickey which is its nearest higher peak. The mountain was named by famed explorer Dr. Frederick Cook for Edward Barrill (1861-1946), a horse packer from Darby, Montana, who was his sole companion during his 1906 claim to be the first to climb Mount McKinley. The claim was later disproved, and in 1909 Barrill signed an affidavit stating that they had not reached the summit. Cook referred to his companion as Barrille in his accounts of the expedition, and Barrille remains as the official spelling used by the United States Geological Survey.
