Blackfeet Nation

The Blackfeet Nation, also known as the Blackfeet Tribe of the Blackfeet Indian Reservation, is an Indian reservation and headquarters for the Siksikaitsitapi people in the United States. Located in Montana, its members are composed primarily of the Piegan Blackfeet band of the larger ethnic group historically described as the Blackfoot Confederacy. It is located east of Glacier National Park and borders the Canadian province of Alberta. Cut Bank Creek and Birch Creek form part of its eastern and southern borders. The reservation contains 3,000 square miles (7,800 km²), twice the size of the national park and larger than the state of Delaware. It is located in parts of Glacier and Pondera counties.
