Mystery of the Mega Flood

For hundreds of years, geologists were confused on how the Channeled Scablands were created. At first, they thought a huge river that had once existed, created the Scablands. This idea, however, was shot down by the fact that there are giant pothole formations that could not have been created by a river. Erratics, large granite rocks, are randomly placed around the Scablands as well, negating the possibility of a river making such a landscape. Finally, geologists were able to come to a conclusion. By observing large ripples left on the floor of the Scablands, they were able to conclude that a giant flood had to create the diverse landscape. They discoverd that Glacial Lake Missoula, located in Montana, had to have burst. A glacier at the front of the lake created a plug, stopping the lake from overflowing, until it could not hold anymore. Super-cooled water ran through the cracked glacier and caused all the lake water to rush towards the Pacific, creating the Channeled Scablands.
