In the record
Ceded from the Umatilla reservation under an October 1888 act; a December 1888 order fixed the line between this land and the reduced reservation. The area covers about 172 thousand acres in what is now Oregon.
The 1899 record names Umatilla as the people of this land.
Today, Confederated Tribes of the Umatilla Indian Reservation carries the history of the people named here.

Shapes come from C. C. Royce’s 1899 maps as georeferenced by the US Forest Service. They are approximate and are not legal descriptions of land. Royce recorded land the United States treated as ceded; the shape does not show a nation’s territory.
