Alaska's ghost towns follow its booms. The Klondike rush made Dyea, at the foot of the Chilkoot Trail, a boomtown for the winter of 1897 to 1898. Gold found on Otter Creek on Christmas Day 1908 built Iditarod and Flat, and the Fortymile country still has Chicken. Copper made Kennecott, whose mines shipped ore until the last train left on November 10, 1938. Salmon canneries such as Portlock on the Kenai coast emptied in the 1940s as families moved to Port Graham and Nanwalek, and the Alaska Railroad left Knik behind when it was routed 13 miles to the north. Disaster emptied others: the 1918 influenza killed every resident of York, west of Wales, and the 1964 earthquake dropped Portage below the tides and ended the village of Afognak.
Many places on the list are former Alaska Native villages, left after epidemics, floods or relocations, like King Island, whose people moved to the mainland after the Bureau of Indian Affairs closed its school. The sites are spread from the Aleutians to the Canadian border, and most have no road. What survives ranges from Kennecott's mill town, kept by the National Park Service, and the Independence Mine camp in a state historical park, to a bank vault at Iditarod and a ghost forest at Portage. Much of the land around the old villages belongs to Alaska Native corporations and needs a permit.
