Bretz's Flood: The Remarkable Story of a Rebel Geologist and the World's Greatest Flood

Bretz's Flood: The Remarkable Story of a Rebel Geologist and the World's Greatest Flood by John Soennichsen

Eastern Washington state has a bizarre landscape. There are "dry falls" and other large geological formations. J. Harlen Bretz believed these came from a large flooding event. Other geologists scoffed at this. (They were also reluctant to accept this because it could seem to give credence to the biblical flood.) Eventually, many of the old geologists died off and Bretz's view became accepted. Lake Missoula is seen as the source of this flood. 

Bretz was originally from the midwest. He taught high school in Seattle. He later returned east and taught at the University of Chicago and continued teaching and engaging in fieldwork. He lived into his late 90s as he finally saw his views accepted.
