The wîhtikôw (windigo) is the cannibal monster of the Cree winter: a gaunt or gigantic man-eater with a heart of solid ice, associated with famine, isolation, and the north. Cree tradition holds that a person could become wîhtikôw by resorting to cannibalism in famine, by dreaming of the being, or through hostile sorcery, and communities took urgent measures, including melting the ice heart with fire or burning the body, to stop a windigo before it killed. Documented windigo cases from the eighteenth to the early twentieth century, especially in northern Manitoba, Saskatchewan, and Alberta, made this being one of the most intensively studied figures of Algonquian religion; in a well-recorded 1896 case at Trout Lake, Alberta, the afflicted man spoke of ice rising within his body and begged his relatives to kill him. In the East Cree communities of James Bay the same monster is known as atuush.
