Program Description

It was the greatest flood of the past two million years, and it posed a giant scientific riddle. The name "scablands" perfectly suits the scarred and wounded landscape in eastern Washington State, 200 miles east of Seattle, which baffled most geologists throughout the 19th century and much of the 20th. To them, no plausible explanation fit all the facts. But a geologist named J Harlen Bretz outlined a startling hypothesis. His fieldwork convinced him that an enormous catastrophe had taken place almost overnight when a titanic flood engulfed the region. Bretz was unable to say where all the water had come from, but a colleague named Joseph Thomas Pardee was certain that the answer lay in the region around Missoula, Montana, where he saw traces of an enormous ice dam half a mile high, which had blocked a valley and created an enormous lake behind it. With the help of stunningly realistic animation, NOVA takes viewers back to the Ice Age to reveal what happened when the dam broke, unleashing a titanic flood.
