How were the Grand Canyon and Great Lakes formed? The Big Picture Episode 10
Update: 2025-07-06
Description
This episode of the Big Picture explores the possibility that massive, rapid flooding events played a central role in shaping major geographic features across North America — including the Grand Canyon, the Great Lakes, and the Channeled Scablands. Randall & Becket walk through detailed geomorphic evidence suggesting that these landforms may not have been formed slowly over millions of years, but rather through sudden, high-energy processes involving enormous volumes of water.
