The Klamath people lived in the area around the Upper Klamath Lake (E-ukshi - “Lake”) and the Klamath, Williamson (Kóke - “River”), Wood River (E-ukalksini Kóke), and Sprague (Plaikni Kóke - “River Uphill”) rivers. They subsisted primarily on fish and gathered roots and seeds. While there was knowledge of their immediate neighbors, apparently the Klamath were unaware of the existence of the Pacific Ocean. Gatschet has described this position as leaving the Klamath living in a "protracted isolation" from outside cultures.
