In the record

Given up by the Shoshoni and Bannock in the July 1868 Fort Bridger treaty, which gave up their right to all land outside their reservation. The area covers about 45 million acres in what is now Colorado, Idaho, Montana, Utah and Wyoming.

The 1899 record names Bannock and Shoshone (Shoshoni) as the people of this land.

How it was taken: a treaty or agreement. The treaty text records a negotiated reservation treaty signed by chiefs and headmen; the Supreme Court in 1937 describes it as an exchange of reservations, and no source cited describes coercion.

Today, Shoshone-Bannock Tribes of the Fort Hall Reservation, Eastern Shoshone Tribe of the Wind River Reservation, Wyoming, Northwestern Band of the Shoshone Nation and Te-Moak Tribe of Western Shoshone Indians of Nevada (Four constituent bands: Battle Mountain Band; Elko Band; South Fork Band; and Wells Band) carry 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.
