The Great Lakes: Our Freshwater Treasure

This informational picture book explains how the Great Lakes formed, beginning with snowfall and glaciers whose development started two million years ago. It notes that the lakes contain most of North America’s freshwater and follows a drop of water from Lake Superior through Huron, Michigan, Erie, Niagara Falls, Lake Ontario, and the St. Lawrence River to the Atlantic Ocean. A final section considers human relationships with the lakes, including Native peoples, European settlers whose actions caused major pollution, and Indigenous activists who led cleanup efforts.
