Pend Oreille
Their traditional territory was reaching up and down the drainage systems of the Flathead River, Clark Fork, and Pend Oreille rivers. It extended from roughly present-day Plains, Montana, westward along the Clark Fork River, to Lake Pend Oreille and Priest Lake in Idaho, and the Pend Oreille River ("Ntxwe", meaning "river") in eastern Washington and into British Columbia (Canada).
