The Blackfoot name for the mountain is Nínaiistáko.[6][2] The mountain was seen by white explorers in the late 18th century and was known as "Kings Peak" on maps produced in the United Kingdom in 1795. The name was changed in the late 19th century in reflection of Blackfeet naming of the mountain which was "Great Chief". When Glacier National Park was created in 1910, the summit and most prominent eastern slopes of the mountain were located within the park, leaving only the lower slopes within Blackfeet jurisdiction.[5]
