Sculpted by Floods: The Northwest's Ice Age Legacy
Special | 57m 20sVideo has Closed Captions
Join the scientists as they struggle to decipher this story.
It is a story of the earth's power, scientific discovery and human nature - one touted by enthusiasts as the greatest story left untold. During the last ice age, floods flowing with ten times the volume of all the world's current rivers combined inundated the Northwest. What left behind was a unique and often puzzling landscape that we call home.
