The Nez Perce covered a large area, overlapping three states. The borders of the states are clearly shown by the dotted lines. The light gray is the entirety of the Nez Perce territory.
The Lakota occupied a large area of the northern Midwest. Their territory overlapped five states, but the main area that they resided was the Dakotas. The yellow area shows where they lived before they were forced off of their land.
