Conclusion - Footprints of the Ice Age: part 14 of 14

This segment describes the effects of rebounding and upwarping from the retreat of the Laurentide ice sheet from the Upstate New York region. Scientists predict that at some point in the future this rebounding might result in the Great Lakes draining southward instead of northward through the St. Lawrence River basin.
Excerpted from the television documentary "Footprints of the Ice Age" produced and narrated by by Michael S. Ameigh.
