Henry Peter Karstens was the first superintendent of Denali National Park, from 1921 to 1928. He was the guide and climbing leader of the first complete ascent of Denali in 1913, with expedition members Hudson Stuck, Walter Harper and Robert Tatum. John Fredson and Esaias George were two young Gwich'in Alaska Natives who supported the party.

Hudson Stuck was a British native who became an Episcopal priest, social reformer and mountain climber in the United States. With Harry P. Karstens, he co-led the first expedition to successfully climb Denali in June 1913, via the South Summit. He published five books about his years in Alaska. Two memoirs were issued in new editions in 1988, including his account of the ascent of Denali.
