The Tukudeka or Mountain Sheepeaters are a band of Eastern Shoshone, who later joined the Northern Shoshone. They traditionally lived in the central Sawtooth Range of Idaho. Bands were very fluid and nomadic, and they often interacted with and intermarried other bands of Shoshone. Today the Tukudeka are enrolled in the federally recognized tribe, the Shoshone-Bannock Tribes of the Fort Hall Reservation of Idaho.
