The Swift River (Deg Xinag: Xelinhdi; Dena'ina: Huch'altnu) is a tributary, about long, of the Kuskokwim River in the U.S. state of Alaska. Formed by meltwater from several glaciers in the Revelation Mountains of the Alaska Range, the river flows generally west and northwest to meet the larger stream northeast of Sleetmute. The Swift is upriver from the village of Stony River, not Sleetmute. References Rivers of Bethel Census Area, Alaska Rivers of Alaska Rivers of Unorganized Borough, Alaska
