Confederated Tribes of the Umatilla Indian Reservation, Oregon
Lands ceded to the United States by treaty, law or executive order, 1855–1888, as Charles C. Royce recorded them in 1899 — 28,849 km² in 4 cessions across Oregon, Washington.
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.
