The Great Lakes.

Description:

Biting deep into the middle of North America, the Great Lakes lie like inland seas halfway across the continent, from the St. Lawrence to within eighty miles of the Mississippi - from the Alleghenies to the rocky hills of the Canadian Shield. They dominate the pattern of life of a region bigger than France. Their old beaches, bottoms, deltas and sandbars are major features of the land. Animals adapting to their meadows, dunes and ancient lake plains have evolved into separate subspecies. It is a region so great that it includes two climate zones, three main types of forest, some of the most intensely cultivated sections of the continent, and areas of wilderness that look much as they did before man arrived on earth.
