It's 3000 years old, but it's the youngest river on earth, lying in a 650 million year-old bed. It accounts for 20% of the world's fresh water, but boasts 7 foot tides. It's the amazing St. Lawrence River and it rivals the Amazon and the Nile for sheer size and fascination.
This extraordinary 4-part documentary is a voyage of discovery down the mighty St-Lawrence from the Gulf to the Great Lakes, deep into the heart of the continent. It's science, adventure and history all rolled into one!
Along the way, we meet biologists, geologists, physicists, divers, historians, and archeologists who share their knowledge and passion for the river, as well as their concerns for its health and future.
