This informative book follows the St. Lawrence River, once a main route of the fur and timber trades. This important commercial waterway forms part of the boundary between Canada and the United States and connects the Great Lakes with the Atlantic Ocean. Today, a system of canals, dams, and locks lets seagoing ships travel all the way to Lake Superior.
