Mysteries of the Great Lakes is a timely film. All across the Great Lakes basin, there is a renewed interest in the health of the Lakes, and an increased awareness of the importance of this fresh water resource to the social and economic vitality of North America. Dubbed ‘inland seas’ by early European explorers, the Great Lakes have some of the most spectacular wilderness scenery on earth, and a fifth of all the planet’s fresh water. Today, 25% of all Canadians, and 10% of Americans live on the Great Lakes. In addition, one in every three Canadians and one in every seven Americans rely on the Great Lakes for their fresh water. Through several interlocking stories, including the story of maritime commerce and the ships that move cargo through the inland waterway, Mysteries of the Great Lakes will take you on a journey through the greatest lake system in the world, and showcase the amazing geography, ecology, science, and history of the region through the most powerful film medium in the world - IMAX.
