The Klamath people are a Native American tribe of the Plateau culture area in Southern Oregon and Northern California. Today Klamath people are enrolled in the federally recognized tribes:
Achomawi are the northerly nine bands of the Pit River tribe of Palaihnihan Native Americans who live in what is now northeastern California in the United States. These 5 autonomous bands of the Pit River Indians historically spoke slightly different dialects of one common language, and the other two bands spoke dialects of a related language, called Atsugewi. The name "Achomawi" means river people and properly applies to the band which historically inhabited the Fall River Valley and the Pit River from the south end of Big Valley Mountains, westerly to Pit River Falls. The nine bands of Achumawi lived on both sides of the Pit River from its origin at Goose Lake to Montgomery Creek, and the two bands of Atsugewi lived south of the Pit River on creeks tributary to it in the Hat Creek valley and Dixie Valley.
The Atsugewi are Native Americans residing in northeastern California, United States. Their traditional lands are near Mount Shasta, specifically the Pit River drainage on Burney, Hat, and Dixie Valley or Horse Creeks. They are closely related to the Achomawi and consisted of two groups. The Atsugé traditionally are from the Hat Creek area, and the Apwaruge are from the Dixie Valley. They lived to the south of the Achomawi.
The Mono are a Native American people who traditionally live in the central Sierra Nevada, the Eastern Sierra, the Mono Basin, and adjacent areas of the Great Basin. They are often grouped under the historical label "Paiute" together with the Northern Paiute and Southern Paiute – but these three groups, although related within the Numic group of Uto-Aztecan languages, do not form a single, unique, unified group of Great Basin tribes.
