The Carolina Bays are the most prevalent geological features of the Atlantic coastal plain, but few geology books mention the Carolina Bays, and when they mention them, they dismiss them as if they were just sand dunes or thermokarst lakes. Nothing could be further from the truth. The Carolina Bays have mathematically precise elliptical geometry, and this gives them a unique niche in the wide spectrum of possible geological features.
Since ellipses are conic sections, this implies that the Carolina Bays originated as inclined conical cavities and that they became shallow elliptical features through viscous relaxation. This book proposes that an extraterrestrial impact on the Laurentide Ice Sheet during the last Ice Age ejected pieces of glacier ice in ballistic trajectories, and that the secondary impacts of the glacier ice liquefied the ground and created inclined conical cavities that produced the Carolina Bays. Nebraska has similar elliptical geological features, and like the Carolina Bays, projections of their major axes converge by the Great Lakes. The saturation bombardment of glacier ice chunks that made the bays killed the North American megafauna from the Rocky Mountains to the East Coast of the United States. The global winter that ensued after the extraterrestrial impact is called the Younger Dryas cooling event.
The ubiquitous geological evidence of a cataclysm provided by the Carolina Bays has been ignored by scientists who dismiss the elliptical geometry of the bays and their radial orientation while insisting that the diverse dates of the terrain where the bays are found indicate that the bays were created by wind blowing across pools of water over millennia, although there is no proof that such processes can form elliptical features.
This book describes the acrimonious controversy between the proponents of impacts and the proponents of uniformitarian wind-and-water processes.
