The team completes the expedition by circumnavigating the mountain.
1906: Dr. Cook claims to be the first to reach the summit of Mt. McKinley.

1912: The Fairbanks Daily Times expedition led by the newspaper's editor, Ralph Cairns, attempts to climb Mt. McKinley, reaching 9,200 feet on the Muldrow Glacier. The Parker-Browne expedition starts in Seward and travels by dog team through Anderson Pass to Mt. McKinley, reaching the 20,000-foot level before retreating.
1913: First ascent of Mt. McKinley's 20,310-foot south summit achieved by Hudson Stuck, Walter Harper, Harry Karstens, and Robert Tatum. Harper, a Native Alaskan, is first to set foot on top.
On June 7, 1913 four men -- Walter Harper, Harry Karstens, Hudson Stuck, and Robert Tatum -- made mountaineering history by being the first to set foot on Mt. McKinley's south summit. Learn more about the expedition and what it took for these four men to reach the top. (Running time 05:20, closed captions)
