Klamath and Modoc are closely related dialects of a Penutian language. Klamath is spoken around Klamath and Agency Lakes in south-central Oregon, and Modoc is spoken around Tule Lake and the lava beds in California. Very few people speak either dialect, though efforts are currently being made to revive them.
A number of methods of writing Klamath have been devised by linguists, such as Albert S. Gatschet, who published a dicionary, grammar and texts during the 1870s, and M.A.R. Barker who did the same during the 1960s, and by tribal elders. Barker's system most accurately represents the sounds of the language.
