There’s power in the Flood

“In the late spring and early summer of 1983, there was snowfall in the high country of the upper Colorado River basin causing excessive runoff to pour into Lake Powell behind Glen Canyon Dam in northern Arizona…engineers decided to… increase the flow to 32,000 cubic feet per second out through the 40-foot-diameter spillway tunnel…[in just a few days] the flow of water in the spillway tunnel…became red [the color of the underlying and now exposed sandstone], and noticeable ground vibrations (earthquakes) were felt. The spillway tunnel was immediately closed, so that damage could be evaluated. A survey team discovered extensive damage in the spillway tunnel due to the process called cavitation. The water was moving so swiftly and in such a large volume that vacuum bubbles were produced in the water that imploded in an explosive process that delivered hammer blows to the concrete lining of the tunnel at pressures estimated to be as much as 440,000 lbs per square inch! It was estimated that the cavitation was pulverizing the concrete, steel and sandstone at a rate in excess of 1,000 cubic feet per second. The concrete lining of the tunnel had been gouged out in several huge pits. In one place, a hole 32 feet deep, 150 feet long, and 40 feet wide had been ripped out of the three-foot-thick, steel-reinforced concrete and into the red sandstone bedrock beneath which required 63,000 cubic feet of concrete to fill. This illustrates how destructive a global flood would have been and how it could easily have gouged out features like the Badlands of South Dakota and the Grand Canyon in very short periods of time. Millions of years of erosion are not necessary.

  1. […] 3. Rob Lester, at Creation Faith Facts, gave a great “fact” this week concerning the Genesis 6 flood. (And the title of the post is great, too!) Enjoy “There’s Power in the Flood.” […]
