Lake Superior (French: Lac Supérieur) is the largest of the Great Lakes of North America. The lake is shared by the province of Ontario to the north in Canada, the states of Minnesota to the west, Wisconsin and Michigan to the south in the United States. It is generally considered the largest freshwater lake in the world by surface area. It is the world's third-largest freshwater lake by volume and the largest by volume in North America.
The rocks of Lake Superior's northern shore date back to the early history of the earth. During the Precambrian (between 4.5 billion and 540 million years ago) magma forcing its way to the surface created the intrusive granites of the Canadian Shield. These ancient granites can be seen on the North Shore today. The first people came to the Lake Superior region 10,000 years ago after the retreat of the glaciers in the last Ice Age. They are known as the Plano, and they used stone-tipped spears to hunt caribou on the northwestern side of Lake Minong.
