Whiteshell Provincial Park has many pink granite ridges, cliffs, and flat granite areas used for petroform making by First Nation peoples. There is also archaeological evidence of ancient copper trading, prehistoric quartz mining, and stone tool making in the area. The copper trade, which extended toward Lake Superior, began approximately 6,000 years ago. Many artifacts and prehistoric camps were discovered in Whiteshell Provincial Park and are protected under the Heritage Act of Manitoba. The park is still used by aboriginal peoples for wild rice harvesting and ceremonies.
