Formerly and often called Mount McKinley, Denali is the highest mountain in North America. It is in south-central Alaska, in Denali National Park. The West Buttress route is considered the best path to ascend Denali. Frederick Cook, a man notorious for having faked the discovery of the North Pole, is now believed to have also faked his ascent of the mountain in 1906 as well, leaving a climbing party seven years later with the honor.
