Traces of the Flood and the Ice Ages
The book goes on to quote a 1961 Scientific American article that says that when the ice ages were first recognized to have occurred, some of the evidence was later shown to be caused by the flow of water rather than ice. While this is true, please note that as geologists gained experience during the past two centuries they found and corrected their own errors. Also note that in the thirty years since 1961, a revolution has occurred in the earth sciences. A huge amount of evidence now exists that shows beyond all reasonable doubt that ice ages did occur.
Geologists have also found that large floods have occurred. But the evidence for them is quite different from the evidence that today is interpreted as due to ice ages. The largest documented flooding occurred at the end of the last ice age in the Pacific Northwest of the United States. Its effects are clear and unambiguous, as I have seen for myself when flying over parts of Oregon and Washington. A line of hills along the Columbia River just west of Portland, Oregon was undercut by the water as it rounded the inside corner of a large bend. It looks like the undercutting of sand on a beach by a small stream, but on a far larger scale. The evidence becomes even more striking when one is flying at 25,000 feet over eastern Washington and Oregon shortly after sunrise. The early morning light adds sharp relief to the water carved features. Just as striking, these features are not evident in the high country outside the flooded area, nor are they evident across the rest of the United States, even in areas that were under continental ice sheets.
I next describe this flooding in detail, to show what the effects of a truly large flood are. While reading this, try to think of other places where these effects are seen. If you can document it, I'd certainly like to know about it.
