E'ometaeso

E'ometaeso lies in the badlands and grassland of the northern Plains, along the Little Missouri River where the river cuts deep gullies through clay and sandstone. Cheyenne and Lakota bands hunted bison across these uplands, and the river bottoms offered cottonwood for shelter and fuel. The river's name appears in a Cheyenne-language word list, which gives it as the source of this place's name. Travellers reached the valley by following buffalo trails between the Missouri and the Black Hills, and the river's cut banks marked the way across the rough country.
