Michigan's Ottawa, Ojibway, and Potawatomi Indians relied directly upon the forests and waters of their Great Lakes home for food, shelter, and clothing. Life in this beautiful but sometimes unpredictable and unyielding environment required a well developed technology crafted by local artisans with the materials from their home region. Ojibway people between Sault Ste. Marie and the Straits of Mackinac supported themselves primarily by gathering wild foods such as berries and maple sap, hunting for large and small game, and by harvesting rich catches of whitefish and lake trout.
