The Rise and Fall of the Great Lakes

A lesson in geography, which concludes that although the Great Lakes have had their ups and downs, nothing has been harder to take than what humans have done to them lately. In the film, a lone canoeist lives through the changes of geological history, through Ice Age and flood, only to find himself in the end trapped in a sea of scum.
