The following is taken from a page on the University of Washington’s website. It recounts a conversation with David Montgomery, a geomorphologist and professor of Earth and space sciences at the UofW, who has just written a new book titled: The Rocks Don’t Lie: A Geologist Investigates Noah’s Flood (W.W. Norton):
For nearly two centuries there has been overwhelming geological evidence that a global flood, as depicted in the story of Noah in the book Genesis, could not have happened. Not only is there not enough water in the Earth system to accound for water levels above the highest mountaintop, but uniformly rising levels would not allow the water to have the erosive capabilities attributed to Noah’s Flood, Montgomery said.
Some rock formations millions of years old show no evidence of such large-scale water erosion. Montgomery is convinced any such flood must have been, at best, a regional flood. . . .
If your world is mall enough, all floods are global,” he said.
