Lake Superior Hides the Scar of a Continent That Nearly Split Apart

Beneath the largest freshwater lake in the world lies a wound in the Earth's crust more than a billion years old. In this video, retired geography teacher Warren Wilder shares 20 remarkable geographic facts about Lake Superior and the Midcontinent Rift, a 1,200-mile scar left behind when North America nearly tore itself in two. You'll discover how the rift flooded the region with lava, why the Keweenaw Peninsula holds some of the purest native copper on Earth, how Lake Superior agates were born, and why the biggest geologic feature in the Midwest is one you can't see from the road.
