Description
The Koyuk River (also spelled, Kuyuk) (Inupiaq: Kuuyuk; Yup'ik: Kuiguk) is a river on the Seward Peninsula of western Alaska, in the United States. The river originates in the interior of the peninsula, at the Lost Jim Lava Flow of the Bering Land Bridge National Preserve, where it flows southeast towards the mouth of Norton Bay on Norton Sound. The native village of Koyuk is located at its mouth. The two major tributaries are the Peace and Salmon rivers; other tributaries include Dime and Sweepstakes.
