History of the River

The Gros Ventre (English: ; from French: "big belly"), also known as the Aaniiih, A'aninin, Haaninin, and Atsina, are a historically Algonquian-speaking Native American tribe located in north central Montana. Today the Gros Ventre people are enrolled in the Fort Belknap Indian Community of the Fort Belknap Reservation of Montana, a federally recognized tribe with 3,682 enrolled members, that also includes Assiniboine people or Nakoda people, the Gros Ventre's historical enemies. The Fort Belknap Indian Reservation is in the northernmost part of Montana, just south of the small town of Harlem, Montana.
