Blackfeet. The Blackfeet Nation, officially named the Blackfeet Tribe of the Blackfeet Indian Reservation of Montana, is a federally recognized tribe of Siksikaitsitapi people with an Indian reservation in Montana. Tribal members primarily belong to the Piegan Blackfeet band of the larger Blackfoot Confederacy that spans Canada and the United States. The Blackfeet Indian Reservation 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, twice the size of the national park and larger than the state of Delaware. It is located in parts of Glacier and Pondera counties. The Blackfeet settled in the region around Montana after 1600 CE. Previously, they resided in an area of the woodlands north and west of the Great Lakes. Pressure exerted by British traders at James Bay in present day Canada on the Algonquin-speaking tribes in the area drove the Blackfeet out onto the Northern Plains. They eventually acquired firearms and horses, and became a formidable example of the classic Plains Indian culture. They were a powerful force, controlling an area that extended from current day Edmonton, Alberta Province, nearly to Yellowstone Park, and from Glacier Park to the Black Hills of South Dakota. The Badger-Two Medicine area is a significant sacred site for the tribe. In the late 19th century, Blackfeet territory was encroached on by European Americans and Canadians, and various branches of the people were forced to cede lands and ultimately move to smaller Indian reservations in the United States and reserves in Canada. Adjacent to their reservation, established by Treaty of 1896, are two federally controlled areas: the Lewis and Clark National Forest, set up in 1896, which contains the Badger-Two Medicine area, an area of 200 square miles; and Glacier National Park, both part of the tribal nation's former territory. The Badger-Two Medicine area is sacred to the Blackfeet people. This sacred part of the Rocky Mountain Front was excluded from Blackfeet lands in a Treaty of 1896, but they reserved access, hunting and fishing rights. Since the early 1980s, when the Bureau of Land Management approved drilling rights leases without consultation with the tribe, the Blackfeet have worked to protect this sacred area, where they practiced their traditional religious rituals. The US federal government suspended all leasing activities for drilling in this area in the 1990s, and in 2007 the Bush administration made permanent a moratorium on issuing new permits. Many leaseholders had already relinquished their leases, and in November 2016 the Department of Interior announced the cancellation of the 15 drilling rights leases held by Devon Energy Corporation in the Badger-Two Medicine area. The Blackfeet had documented that the area was not a wilderness, as the Bob Marshall Wilderness Complex was designated in 1964, but a human landscape shaped by and integral to their culture. Elevations in the reservation range from a low of 3,400 feet to a high of 9,066 feet at Chief Mountain. Adjacent mountains include Ninaki Mountain and Papoose. The eastern part of the reservation is mostly open hills of grassland, while a narrow strip along the western edge is covered by forests of fir and spruce. Free-ranging cattle are present in several areas, sometimes including on roadways. Several waterways drain the area with the largest being the St. Mary River, Two Medicine River, Milk River, Birch Creek and Cut Bank Creek. There are 175 miles of streams and eight major lakes on the reservation. The reservation is east of the Lewis and Clark National Forest in Montana, which contains the Badger-Two Medicine area, sacred to the Blackfeet people. The Badger-Two Medicine area is at the Rocky Mountain Front of the national forest. The Blackfeet call the Rocky Mountains the Backbone of the World. Their names for peaks include Morning Star, Poia, Little Plume, Running Crane, Spotted Eagle, Kiyo, Scarface, Elkcalf Bullshoe, and Curly Bear. The 2010 census reported a population of 10,405 living on the reservation lands. The population density is 3.47 people per square mile. The Blackfeet Nation has 16,500 enrolled members. The main community is Browning, Montana, which is the seat of tribal government. Other towns serve the tourist economy along the edge of the park: St. Mary and East Glacier Park Village, which has an Amtrak passenger station and the historic Glacier Park Lodge. Small communities include Babb, Kiowa, Blackfoot, Seville, Heart Butte, Starr School, and Glacier Homes.
