Upper Kuskokwim language

The Upper Kuskokwim language (also called Kolchan or Goltsan or Dinak'i) is an Athabaskan language of the Na-Dené language family. It is spoken by the Upper Kuskokwim people in the Upper Kuskokwim River villages of Nikolai, Telida, and McGrath, Alaska. About 40 of a total of 160 Upper Kuskokwim people (Dichinanek’ Hwt’ana) still speak the language. A practical orthography of the language was established by Raymond Collins, who in 1964 began linguistic work at Nikolai.
