The first ascent of the south (higher) peak occurred in 1913. Denali is approximately 130 miles South-Southwest of Fairbanks, Alaska, 20,310 ft in height, with the upper reaches permanently swathed in snow and glaciers. "Operation White Tower" drew together complex interests. The New England Museum supported scientific, surveying and photographic endeavors during the climb. The U.S. Air Force, interested in cosmic ray research and high altitude camping, helped with logistics, while the Alaska Communications System set up the team with radio support. The National Park Service allowed the use of a ranger station, while Chief Ranger Grant Pearson accompanied the expedition. Four representatives from RKO also took part in the expedition to capture photography, film and written accounts of the climb.
