Koyuk is an Iñupiaq village at the head of Norton Bay, on the right bank of the Koyuk River estuary on the Seward Peninsula, about 129 miles (208 km) east-northeast of Nome and 40 miles (64 km) north of Shaktoolik, Alaska. Village residents trace their ancestry to the Unalit and Malemiut peoples. The river rises at about 1,526 feet (465 m) from a lake in the Bering Land Bridge National Preserve, near the Lost Jim Lava Flow, a basalt sheet covering about 56,960 acres (23,051 ha) that erupted about 1,655 years ago. During the Last Glacial Maximum of the late Pleistocene, from about 26,500 to 19,000 years ago, sea level was roughly 425 feet (130 m) lower, exposing the Bering Land Bridge, or Beringia, which linked Siberia to Alaska. The strait flooded again 13,000 to 11,000 years ago, and archaeologists have found evidence of human habitation in the preserve dating to 12,000 years ago. Lava beds are exposed on both banks of the valley, and rockfall from them has left the riverbed strewn with boulders. The nearby Bendeleben Mountains are mainly metamorphic and granitic rock, and glaciers from two earlier ice ages left till and outwash along their northern front. The 115-mile (185-km) river flows southeast, then south, through tundra wetlands to a tidal estuary. Captain James Cook named Norton Sound in 1778 for Sir Fletcher Norton, then Speaker of the House of Commons, and the bay shares that name.

Lieutenant Lavrenty Zagoskin of the Imperial Russian Navy recorded the village as ‘Kuynkhakmiut’ in 1842 to 1844. Mikhail D. Tebenkov noted the river as ‘Kvyguk’ in 1852, and Alfred H. Brooks of the U.S. Geological Survey fixed its present spelling in 1900. Many residents trace their ancestry to the Malemiut, Kauweramiut and Unalikmiut peoples, who settled the peninsula about 4,000 years ago. They still speak an Iñupiaq language dialect and keep a traditional subsistence lifestyle. Iyatayet, on Cape Denbigh about 38 miles (61 km) southwest, shows at least 4,000 years of coastal occupation. In the late 1800s, whalers hired local men and traded liquor and repeating rifles for ivory, and hunting for meat and fur left muskoxen and caribou virtually eliminated by the 1890s. In 1865, Baron Otto von Bendeleben of the Western Union Telegraph Expedition recorded ‘Konyukmute,’ and William H. Ennis found the village deserted for 13 years ‘on account of sickness and death.’ The Alaska Commercial Company opened a trading post at the mouth in 1879. In 1891, reindeer from Chukotka, Russia, were introduced for a predictable meat supply and economic development; the herd reached 242,000 by 1924. Around 1900 the townsite began to fill, with supplies lightered ashore. By about 1914, boomtowns Dime Landing and Haycock had sprung up around gold and platinum prospects, served by river steamers, and Norton Bay Station followed in 1915.

Climate change now threatens the everyday lives and traditions of Koyuk residents. Less sea ice means more open water, so storm-driven waves can strike harder, and thawing permafrost speeds coastal erosion. The village has experienced coastal flooding, and storm surge is most severe in Norton Sound. Koyuk was among the communities affected by Typhoon Merbok in 2022, and a federal recovery strategy names it among them. Fire is a longstanding part of the landscape too. The Seward Peninsula has more frequent and larger tundra fires than other Alaskan regions, including the 1954 Imuruk Basin fire, the largest tundra fire on record in Alaska, which burned about 416,000 acres (168,348 ha). Fires in 1954, 1957, 1971 and 1977 accounted for more than two-thirds of the area burned on the peninsula since 1950. Spruce stands on the eastern peninsula are especially flammable. Tundra fires have not risen here as sharply as in Southwest Alaska, but models project more fire as warming continues, and burning releases carbon from tundra soils. The Native Village of Koyuk is a federally recognized tribe, and the community, which had 312 residents at the 2020 census, has banned alcohol sales and imports since 1981. Residents still rely on subsistence hunting and fishing. Federal support for climate resilience efforts is uncertain as the Trump administration cuts climate and disaster programs.
