Mystery of the Megaflood

The Scablands is an area in the northwestern section of the United States.  The Scablands is a very interesting area because of all of it's unique features.  With it's large potholes on the ground, large boulders which do not match the terrain, and enormous rock walls which seemed to be etched out by God by hand,  the formation of the Scablands has been asked by many geologists.  Several reasons have arisen to explain how the Scablands came to be. One explanation is rivers formed the rock.  This does not explain the large potholes on the surface and little evidence supports such a claim.  Another explanation was the moving glaciers from the Ice Age. This theory explains how the large boulders could have moved as well as the hanging valleys in the Scablands.  However, the glaciers from the Ice Age never made it to the Scablands, so what really created the Scablands?

Jay Bretts studied the Scablands for many years, and he proposed, at that time, an insane reason about how the Scablands came to be.  He claimed that an enormous flood had come through the Scablands and created the Channel Scablands.  He came to this conclusion by observing the large hills which looked like ripples in the sea from above.  He shared his theory with many geologists at the time, but many rejected his theory immediately since Bretts could not explain where the water from the flood came from.  A geologist hearing Bretts's theory claimed he knew what the source of water was.

The geologist went to Glacial Lake Missoula where it was said ice and water met.  The Clark Fork River and watermarks were along the walls of the Missoula Valley.  It was believed that an enormous block of ice dammed the Clark Fork River, and over time, the water levels gradually rose.  Finally when the ice could not hold the water any longer, the ice exploded and an enormous amount of water rushed out.  The ripples found at Missoula Valley matched the ripples found at the Scablands and these ripples were headed straight at the Scablands. The ice dams were explained in more detail at the Iceland Glacier.  The large ice forms, stops the flow of water, and "super cooled water" forms on the inside of the glacier.  This super cooled water begins to create cracks in the ice glacier.  These cracks would have the water rush through the glacier and start melting the ice.  Over time, the ice would explode and trillions of tons of water would be pouring out of it.

A test at the University of Minnesota proved that the Scablands could have been created overnight.  The powerful rushing water would have enough pressure to create the rock formations and valleys.  The pressure at ground level would create these mini-tornadoes which could have created the potholes on the surface of the Scablands.  Glaciers holding the large rocks and boulders would have been transported with the flood as well.  After many tests to determine the time that this supposed flood could have occurred, it was determined that there was not just one flood that ran through the Scablands.  The KT Boundary tests showed the rock formations at the bottom were nearly twenty thousand years older than the rock formations at the top.  With all this evidence to support the theory, there is no doubt that the creation of the Scablands with all it's unique features came from many megafloods.
