Glacial Lake Missoula

For three weeks due to the weather, we were required to watch different videos during our lab time.  The most interesting video was a discussion on how the Scablands were created.  After several hypotheses, it was concluded that the Scablands were created from one cataclysmic event from the thawing of Glacial Lake Missoula.  Before this conclusion was formed,  the Scablands were to believed to have been formed by a overtime with a number of slow processes.  Later, it was believed that possibly several floods over several years had caused the extensive weathering found in the Scablands.
