Mystery of the Megaflood

The Channeled Scablands in Washington state defied conventional explanations for their formation for decades. Little by little evidence mounted for an old theory that was rejected by the scientific establishment. It involved glaciers, volcanoes, a relatively minor river and a prodigious amount of water.
