The Great Lakes
Series: Geologic Journey
This episode tells the story of the changes in the geology and landscape of the vast central area of North America. In recent geologic history, five interconnected freshwater lakes are formed. We explore a long vanished mountain range, the remains of a tropical salt-water sea and trace the story of a sudden massive flood that drowned vast areas of land.
