More from my Geology Series on Washington State
Best if watched in HD 720p and full screen.
Moses Coulee was formed by the ancient flow of the Columbia River up until the start of the Ice Age floods. Scientists speculate it could have caught the brunt of the first several sudden and massive floods which tore out valleys and sculpted channels. To give you some idea as to the scale of the floods - picture a wall of water hundreds of feet high suddenly blasting its way through this coulee with the residual flow moving away debris the size of large buildings. Cataclysmic would be an understatement.
