The Kobuk River, also known by the names Kooak, Kowak, Kubuk, Kuvuk, and Putnam, is a river located in the Arctic region of northwestern Alaska in the United States. It is approximately 280 miles (451 km) long. Draining a basin with an area of 12,300 square miles (32,000 km2), the Kobuk River is among the largest rivers in northwest Alaska, with widths of up to 1,500 feet and flows reaching speeds of 3–5 miles per hour in its lower and middle reaches. The average elevation for the Kobuk River Basin is 1,300 feet (400 m) above sea level, ranging from sea level at its mouth on the Bering Sea to 11,400 feet near its headwaters in the Brooks Range.

Iñupiaq or Inupiaq, also known as Iñupiat, Inupiat, Iñupiatun or Alaskan Inuit, is an Inuit language, or perhaps group of languages, spoken by the Iñupiat people in northern and northwestern Alaska, as well as a small adjacent part of the Northwest Territories of Canada. The Iñupiat language is a member of the Inuit-Yupik-Unangan language family, and is closely related and, to varying degrees, mutually intelligible with other Inuit languages of Canada and Greenland. There are roughly 2,000 speakers. Iñupiaq is considered to be a threatened language, with most speakers at or above the age of 40. Iñupiaq is an official language of the State of Alaska, along with several other indigenous languages.
