Abstract:
Unique atmospheric conditions during and immediately following the Flood have recently been postulated based on the results of numerical computer modeling. This modeling suggests that the heating of the atmosphere and oceans could have produced conditions suitable for the development of super hurricanes, or “hypercanes.” Unfortunately, the atmosphere provides no historic record of such events. However, proxy records might be found in the rock record. In fact, it is probable that hypercanes would have created large-scale tempestites (i.e., storm deposits) across various portions of the continents while they were covered by Floodwater. Such storm deposits occur across the United States Gulf Coastal Plain. One such stratigraphic unit is the Gosport Sand Member of the Lisbon Formation (Eocene), which extends across southwestern Alabama. A Gosport Sand outcrop at Little Stave Creek in Clarke County exhibits sedimentary evidence that it formed from a single massive hypercane during the Middle Flood Event Division.
