Cape Krusenstern National Monument

Cape Krusenstern National Monument and the colocated Cape Krusenstern Archeological District is a U.S. National Monument and a National Historic Landmark centered on Cape Krusenstern in northwestern Alaska. The national monument was one of fifteen new National Park Service units designated by the Alaska National Interest Lands Conservation Act (ANILCA) of 1980. It was initially declared a national monument under the authority of the Antiquities Act by President Jimmy Carter on December 1, 1978. Cape Krusenstern is primarily a coastal plain, containing large lagoons and rolling hills of limestone. The bluffs record thousands of years of change in the shorelines of the Chukchi Sea, as well as evidence of some 9,000 years of human habitation. The park's central features, 114 beach ridges at the eponymous cape, alternate between sandy and gravelly ridges and narrow ponds. Located entirely above the Arctic Circle in a region of permafrost, the monument's lands include typical thermokarst features.
