Harper Glacier (Alaska)

Harper Glacier is a glacier in Denali National Park and Preserve in the U.S. state of Alaska. The glacier originates on Denali at more than 19000 ft between Denali's North Peak and South Peak, falling to the northeast between the Karsten Ridge and the Taylor Spur. From about 12000 ft it falls between Pioneer Ridge and Karpe Ridge in the Great Icefall down to the Lower Icefall to become Muldrow Glacier. In 1913, the glacier was named by Hudson Stuck after Walter Harper, a Koyukon mountaineer and the first man to reach the summit of Denali.
