The Great Lakes are the result of pooling of glacial meltwater at the rim of the receding glaciers. When the enormous mass of the continental ice sheet retreated the Great Lakes began gradually moving south due to isostatic rebound of the north shore. Niagara Falls is also a product of the glaciation, as is the course of the Ohio River, which largely supplanted the prior Teays River.
