The Carolina Bays are named after the bay trees found growing in the 500,000 mysterious oval shaped depressions, principally located in the eastern states of North America. In Maryland, the bays are called Maryland basins. In Mississippi and Alabama they’re called Grady ponds. In Kansas and Nebraska they’re called Rainwater basins. In Texas they’re called Salinas (because they often contain salty water).
Their characteristics have been presented as evidence of impact damage from a comet or asteroid. This view is hotly disputed, as is the idea that they are of relatively recent origin at the beginning of the Holocene. Emilio Spedicato is one proponent who considers that a relatively recent impact to have been a contributory fact to the ending of the last Ice Age leading to the demise of Atlantis.
A more mundane explanation has been recently offered by Jon Pelletier, assistant professor of geosciences at the University of Arizona in Tucson. He has just published a paper on a series of uniformly shaped and oriented lakes on North Slope of Alaska. Pelletier has offered a credible ‘thaw slumping’ rationalisation for their annual growth. However, I have not seen his explanation for their existence in the first place. Pelletier’s explanation(a) for the Carolinas is based on the dissolving of the underlying limestone in a manner that generated lakes with a uniform orientation. Although he admitted that at that time (2005) his solution is “very speculative”.
The cometary explanation was given additional support in 2007 when a team of researchers from Oregon University outlined evidence that included the Carolinas, for the disintegration of a comet over Eastern Canada around 10900 BC. They claim that apart from the initiation of the Younger Dryas period, it caused widespread destruction across North America and also led to the disappearance of the Clovis culture. Further evidence supporting this view(b) was advanced by other academics in 2008.
Nevertheless, there is also evidence from optically stimulated luminescence (OSL) dating that the bays were formed 80,000 -100,000 years BP, which conflicts with the YD date! My layman’s view is that after 80,000 year I would expect the bays to be much more eroded than they appear to be.
A more recent paper(e) by Antonio Zamora offers an important new concept, namely that the ‘bays’ were created by a meteorite striking the Laurentide Ice Sheet that existed in the Great Lakes region, during the last Ice Age, which in turn produced an enormous hail of ice ejecta which rained down on the eastern seaboard of what is now the United States. In his conclusion he claims “that the new model of slow-velocity impacts from ice ejecta resulting from a meteorite impact on the Laurentide ice sheet explains many of the characteristics of the Carolina Bays, including the lack of shock metamorphism and meteorite fragments.” Zamora has also published in 2012 an ebook entitled Meteorite Cluster Impacts(f), and in his 2015 book, Solving the Mystery of the Carolina Bays, he expands on his theory that the ‘Bays’ were created as a result of an extraterrestrial impact with the Laurentide Ice Sheet. He describes in great detail the mathematical basis for his views.
Zamora, has now had a new paper on the ‘Bays’ published in the peer-reviewed journal, Geomorphology(i), which may help to rekindle discussion on the subject. Although, in my opinion, they are not directly related to the Atlantis narrative, the existence of the Carolina Bays provide very obvious evidence of our catastrophic past.
Ralph Ellis believes that Zamora’s ‘blocks of ice’ ejecta created by the impact should be thought of instead as being more akin to softer ‘slushballs’(g)(h).
*Robert W. Felix, an American architect totally rejects the ice ejecta theory, principally on the grounds that the Laurentide Ice Sheet (LIS) should have disappeared before the creation of the Carolina Bays(l). However, conventional wisdom dates the decline of the LIS to around 9,600 BC(m), coincidental with the arrival of the Carolina Bats! Felix contends in one of his books  that the Bays were formed by millions of gigantic explosions in the sky, explosions triggered by a magnetic reversal!*
The serial sceptic, Paul Heinrich, claims(d) that there is dating evidence, which indicates varying dates for the creation of different Carolinas. The most recent popular work to discuss comprehensively, the origin as well as the conflicting dating evidence for the Carolinas, is The Cycle of Cosmic Catastrophes by Firestone, West and Warwick-Smith. This is an important book that is primarily concerned with a cosmic catastrophe that wiped out the North American mammoth along with other large animals at the same time that the Clovis People disappeared 13,000 years ago. This was also the time of the colder Younger Dryas period.
When the Russian investigator Leonard Kulik studied the Tunguska River area, over which a meteor/asteroid exploded in 1908, he discovered a number of neat oval bog holes that might offer support for either the impact theory or more improbably the theories of Pelletier.
Now, over a century after the Tunguska event, an Italian research team have concluded that it was an asteroid that struck the earth and that nearby Lake Cheko is the impact crater(c).
In 2013 Gernot Spielvogel co-authored Sonnenbomben in which it is suggested that the Tunguska event was caused by a solar plasma ‘bomb’!>Even Nikola Tesla was blamed by some as the perpetrator of the Tunguska event(n).<
Nevertheless, various other theories are still under investigation, including serious consideration of the possibility of an alien spaceship explosion!(j)
