Cape Krusenstern National Monument

Cape Krusenstern National Monument in northwest Alaska covers 649,082 acres on the Chukchi Sea coast, above the Arctic Circle. Its archaeological district holds 114 beach ridges that record more than 5,000 years of human habitation.[1]

Archaeology

The ridges formed about 60 years apart, and the area holds evidence of more than 9,000 years of human occupation, including 5,000 years of Inupiat occupation. Researchers have excavated about one third of the 9,000-acre beach complex.[1]

Establishment

President Jimmy Carter declared it a national monument on 1 December 1978 under the Antiquities Act, and the Alaska National Interest Lands Conservation Act, signed on 2 December 1980, made it a National Park Service unit. Its headquarters are at the Northwest Arctic Heritage Center in Kotzebue.[1]

Establishment and size

President Jimmy Carter declared the monument on December 1, 1978, and it became one of fifteen new National Park Service units when Congress passed ANILCA in 1980. The monument and its archeological district were designated a National Historic Landmark and added to the National Register of Historic Places on November 7, 1973. It covers about 649,082 acres and extends roughly 20 miles inland from the Chukchi Sea coast [2].

Beach ridges

The cape has 114 beach ridges that alternate between sandy and gravelly bands, separated by narrow ponds. They formed about 60 years apart, built by longshore currents over about 6,000 years, and provide a sequential record of habitation [2].

Archaeology

The area holds evidence of roughly 9,000 years of human occupation. Paleo-Arctic sites on the mainland date to about 10,000 to 7,000 years ago, the Palisades site to about 6,000 years ago, the Western Thule culture existed from 950 to 1400 AD, followed by the Kotzebue culture from about 1400 to 1850. Researchers have excavated about one third of the 9,000-acre beach complex [2].

Inupiat and subsistence

The beach ridges preserve evidence of about 5,000 years of Inupiat occupation. Subsistence hunting by local residents is permitted, and about 19 percent of monument lands are owned by Native corporations [2].

Wildlife and geology

Mammals include caribou, brown bears, wolves, and wolverines, and marine mammals include bowhead, gray, and beluga whales and several seal species. Five salmon species, Arctic char, Dolly Varden, and northern pike are found, and the spectacled eider and Steller’s eider are listed as threatened. The land is mostly coastal plain with large lagoons and limestone hills, and permafrost produces pingos, ice wedges, and thaw ponds. The monument recorded 17,736 visitors in 2024 [2].
