Tsunami on South Atlantic Coast
Geological formations suggest that a wall of water, at least 100 feet high, swept into the interior of Georgia. It was at least 70 feet high in northeast Florida. The catastrophic wave could have been much higher.
Residents of the South Atlantic Coastal Plain are accustomed to seeing ridges, terraces and hills, composed of sand and fossilized marine life, deep within the interior of the region. The Trail Ridge is the best known of these sand formations. It runs parallel to and about 40 miles from the Atlantic Coast. The Sand Hills Region runs from near Columbus, GA several hundred miles northward to near Richmond, VA. It can be as far as 180 miles from the coast. Near the Atlantic Coast sandy dunes and terraces that are parallel to the coastline can be as closely spaced as a few hundred yards.
Geologists have traditionally explained these numerous sand formations as the remnants of ancient beaches and islands when ocean levels were much higher. Many actually look like islands within the flat landscape of the Coastal Plain.
Scarcely noticed in the past was a chain of much higher ridges and bluffs that do not run parallel to the coast line, but zigzag along a ellipsoid curve. They mark the impact of a massive asteroid or comet that would have killed all humans and wildlife along the South Atlantic Coast. The most likely candidate is a comet that struck the region in 539 AD.
