The Great Lakes
Geologic Journey: The Great Lakes tells the story of the dramatic changes in the geologic history and landscape of this region, which has only recently taken the form of the five, great, interconnected lakes. In this episode audiences are shown the roots of a long vanished mountain range that once rivalled the Himalayas, explore the remains of a tropical salt-water sea, and trace the story of a sudden massive flood that drowned vast areas of land. From moraines, to tarn lakes, to the majestic Niagara Falls, the topography and geology of the Great Lakes region is unparalleled, strikingly beautiful and a place of wild contrasts.

It is truly “a wild, rocky place whose grandeur and mystery drew men to commune with the spirit of the sea…a place where man is and forever will be only a visitor.”
