New Technology Allows Us to See The Lake Beds of The Great Lakes
This fascinating video shows how they filmed the documentary, Draining the Great Lakes. A visual look at what is at the bottom of the Great Lakes of North America….
The Great Lakes, the largest freshwater system in the world situated in North America along the Canadian and the United States of America border. The five great lakes, Lake Superior, Lake Huron, Lake Michigan, Lake Erie and Lake Ontario contain about 21% of the world’s surface fresh water. These massive lakes formed just 10,000 years ago during the last glacial period, ice sheets carved deep basins in the land and as the ice melted they filled the basins and the great lakes formed.
- Lake Ontario is the smallest lake at just 7,340 square miles.
- Lake Erie – 9,910 sq. miles
- Lake Michigan 22.300 sq miles
- Lake Huron 23,000 sq. miles
- Lake Superior 31,700 sq. miles is the largest.
Four of the great lakes are approximately the same elevation of sea level. The only one that isn’t Lake Ontario, is significantly lower. The four at “sea level” are often referred to as the Upper Great Lakes.
This fascinating video tells the story of how the great lakes were formed 10,000 years ago. It also used modern technology to “drain” the lakes in order to see what is at the bottom and the results are just amazing…
