The primary tribal range from roughly Plains, Montana, westward along the Clark Fork River, Lake Pend Oreille in Idaho, and the Pend Oreille River in Eastern Washington and into British Columbia was given the name Kaniksu by the Kalispel peoples. The Kalispel are one of the three tribes of the Confederated Salish and Kootenai Tribes of the Flathead Nation.
