The Chastacosta, including the Coquille, Galice (Taltushtuntude), Tututni (Lower Rogue River Indians), and the Umpqua, lived in southwestern Oregon along the Lower Rogue, Coquille, and Illinois rivers. They spoke Athapaskan languages and numbered less than fifty in 1970. They are now nearly extinct.
