Catastrophic Flood Dynamic Database

Western USA

The Grand Canyon of Arizona is said to resemble some of the submarine canyons in continental shelves. Creationists have claimed the canyon is evidence for catastrophic erosion, perhaps when the rocks were still not fully consolidated. The conventional explanation is that the canyon was carved out by the Colorado River in conditions much like the present, but this mechanism would be unlikely to work for submarine canyons.

In North Dakota and Manitoba, so-called Glacial Lake Agassiz  extended over a vast area, exceeding the area of all five of the present Great Lakes. The evidence extends over more than 300,000 square miles, encompassing the present lakes Superior, Winnipeg and Manitoba. In the region there are 35 shorelines at different levels that can be traced for hundreds of miles, many of which are not horizontal. The flatness of the plains is due to the silts deposited from these waters. The drainage of this vast lake was catastrophic.

Elevated shorelines and salt deposits in Utah, Nevada and Idaho indicate former high water levels, that are thought to be those of a vast inland lake with an area of 20,000 square miles called Lake Bonneville. The area is not thought to have been glaciated, but the lake is believed to have formed because of a dam, and was drained catastrophically. Charles Ginenthal wrote:

Lake Bonneville, a reservoir of water estimated to cover 19,000 square miles through Utah, Nevada and Idaho, left great salt deposits covering 100 square miles and discharged itself suddenly, after filling up, to produce a tremendous flood. The general public believes that the lake filled gradually from rainfall during the Ice Age, then suddenly discharged its water when its north-facing earthen dam burst. The dam presumably collapsed during the same general period as did the ice dam which formed the Washington Scablands. According to Robert D. Jarrett and Harold E. Malde of the United States Geological Survey (U. S. G. S.), the discharged water is now reckoned to have amounted to "2.2 times the discharge previously reported and is the second largest flood known to have occurred in the world....Other recent studies of the history of Lake Bonneville show that the volume of water released was 4,700 km3."
Sand hills in northwestern Nebraska are believed to have been caused by water currents; see report from Science Frontiers #93.
