Episode notes
Great Lakes' Global Scale
- The five Great Lakes (Superior, Michigan, Huron, Erie, Ontario) form the largest freshwater area by surface on Earth and second-largest by volume.
- Their combined surface equals roughly the size of the United Kingdom and dominates North American freshwater resources.
Ice Age Origins And Water Volume
- The Great Lakes formed ~14,000 years ago when retreating ice sheets carved deep basins that filled with meltwater.
- Lake Superior alone holds 10% of the world's standing fresh water and more water than the other four combined.
Superior's Name And Ocean-Like Character
- The Ojibwa called Lake Superior 'Gichigami,' later anglicized and popularized in song by Gordon Lightfoot.
- Superior rarely freezes and stays cold year-round, making it feel ocean-like despite being a lake.
