Confederated Salish & Kootenai Tribes of the Flathead Reservation, Montana

Lands ceded to the United States by treaty, law or executive order, 1851–1855, as Charles C. Royce recorded them in 1899 — 113,595 km² in 3 cessions across Idaho, Montana.

A cession records when the United States took title — not the full extent of a homeland, and much land was taken without any treaty. The link between each cession and present-day nations is the one the U.S. Forest Service and the National NAGPRA Program’s dataset records; the nation’s own account comes first.

Named in the treaties as: Flathead · Kootenay · Upper Pend d'Orelles · Nez Percè, Blackfoot and Flathead Nations
