Great Lakes

The Great Lakes (French: Grands Lacs) are a chain of freshwater lakes located in eastern North America, on the Canada – United States border.

They are sometimes referred to as the "Third Coast" by some citizens of the United States. Because of their size, some regard them as inland seas.[citation needed]
