Pukaskwa Pits are depressions left by early inhabitants by ancestors of the Ojibwa, named after the Pukaskwa River, near Lake Superior. Estimations of the dates of their digging range from between 1100 and 1600 CE on the near end, to 3,000 to 8,000 BCE on the far end.

Description
These rock-lined pits are dug in cobblestone beaches and are about one to two meters long and one and a half meter deep. Theories about the purpose of these pits range from hunting blinds to food storage pits to spiritual sites. The larger pits or "lodges" may have been seasonal dwellings with domed coverings, hunting blinds or caches for food. The smaller pits may have been used to cook food or smoke fish. The existence of these pits came into academic light in 1949, and was studied by the Royal Ontario Museum, University of Toronto and Lakehead University.
Pukaskwa National Park
Pukaskwa National Park was established in 1978 to protect a large clustering of these Pukaskwa pits.
