The first documented ascent of Denali (aka Mount McKinley), the tallest peak in North America, was made 100 years ago, on June 7, 1913, with Alaskan Native Walter Harper being the first to reach the summit.
Be sure to check out the University of Alaska’s Museum of the North Tumblr for more details on the actual ascent.
