Kevin A. Casey
Kevin A. & Patrick J. Casey are the American authors of a series of papers currently available on the academia.edu website(a), which are concerned with a globally catastrophic event that occurred 13,000 years ago. providing them with a title of ’13K Theory’. The kernel of their theory is that originally the Earth had two moons that at some later point collided, producing our current Moon, while the remnant of the second one eventually exploded over North America kick-starting what we refer to as the cooler Younger Dryas period.
They claim that this event wiped out megafauna, altered the Earth’s axis and created our mountains, the Earth being generally flat before the dramatic episode! They are adamant that it was not a comet or asteroid that caused the devastation, and so clash with the work of Richard Firestone and his colleagues.
Their final paper is entitled Atlantis Revisited(b), in which they nominate Rockall as being ‘by far’ the most likely location of Atlantis. They also claim that the war between the Atlanteans and the Greeks took place before the 13K Event. Enjoy.
Younger Dryas also known as Dryas III was a mini Ice Age that lasted from around 10,700 BC until around 9600 BC. It is named after a flower that flourished during this relatively short period. In Ireland the period is known as the Nahanagan Stadial and in Britain as the Loch Lomond Stadial. For about thirteen hundred years the glaciers had been slowly retreating until within a short time-span temperatures dropped and they began to advance again. The cause of this cooling is not absolutely clear. One view is that a sudden release into the North Atlantic of vast quantities of fresh water that had been contained by huge ice dams is assumed to have closed down the Gulf Stream, resulting in a twelve hundred year lowering of global temperatures. There is evidence that the change only took one or two decades. The same threat is said to exist today with the possibility of the melting of the Greenland ice cap.
The most recent theory, by Firestone, West and Warwick-Smith, links the onset of the Younger Dryas with the explosion of a comet over North America that led to the extinction of many species, the collapse of the Clovis culture(a)(b) as well as the creation of the Carolina Bays.
A 2014 paper(g) entitled Nanodiamond-Rich Layer Across Three Continents Consistent with Major Cosmic Impact at 12,800 Cal BP by Charles R. Kinzie et al., has developed further the idea of this event being associated with the Younger Dryas. In a similar vein is an article(h) from Megan Gannon.
A recent application of archaeoastronomy by Martin Sweatman and Dimitrios Tsikritsis led them to conclude that the carved symbols at Göbekli Tepe recorded an encounter involving the explosion or impact of part of Encke’s Comet around 13,000 years ago, which triggered the Younger Dryas Event that provided the impetus for the Neolithic Revolution. Sweatman later expanded their work in his book Prehistory Decoded  and in an article on the Ancient Origins website(m).
Kevin A. & Patrick J. Casey maintain that a globally catastrophic event occurred 13,000 years ago(l). The kernel of their theory is that originally the Earth had two moons that at some later point collided, producing our current Moon, while the remnant of the second one eventually exploded over North America kick-starting what we refer to as the cooler Younger Dryas period. They are adamant that it was not a comet or asteroid that caused the devastation, and so clash with the work of Richard Firestone and his colleagues.
In 2015 a paper constraining the impact date to within 100 years using Bayesian statistical analyses, now proposed as 12,835 -12,735 years ago(j).
Coincidentally, Professor Emilio Spedicato independently arrived at the conclusion that it was a cometary impact in the North Atlantic that was responsible for the Younger Dryas. Subsequently, when temperatures rose again it resulted in the flooding of vast areas of low-lying landmasses that in Spedicato’s opinion, included Atlantis, which he locates in Hispaniola.
Conflicting evidence regarding the possibility of the Younger Dryas being caused by such an impact is impartially outlined on the internet(c).
December 2014 saw Graham Hancock raising the issue of a cometary cause for the Younger Dryas and its possible association with ancient Egypt(f).
The November 2013 issue of the BBC Focus magazine (p.30) had a brief article on the impact theory, noting that the northern hemisphere saw a drop of as much as 15°C around 11,000BC. In the absence of a suitable impact crater there is still much scientific scepticism(d).
However in early 2017, further possible evidence of an impact at the start of the Younger Dryas was offered by a team led by Christopher Moore of the University of South Carolina, when they identified a distinct layer of platinum in the soil that coincided with the start of YD. Commenting on this anomaly Moore noted that “Platinum is very rare in the Earth’s crust, but it is common in asteroids and comets.”(i)
In early 2018, two papers were published online(k), reinforcing the YD impact theory and adding evidence that the event resulted in a conflagration that “may have consumed – 10 million km2, or – 9% of Earth’s terrestrial biomass”.*Related to this is a paper by Andrew Collins that draws attention to the ‘Usselo horizon’, a charcoal-rich layer of between 1 and 8 inches, found on all continents, indicating widespread fires, now dated to 12,900 years ago(n).*
Ice cores from Greenland indicate a further cooling period circa 6200 BC that may be related to the abandonment of many Neolithic settlements during this period. Other periods of abrupt climate change have been identified from 3800 BC to 3500 BC and 2800 BC to 2000 BC.
The fact that Plato’s apparent date for the demise of Atlantis, circa 9600 BC, roughly corresponds with the current, best estimate for the date of the Younger Dryas is interesting but unfortunately not conclusive proof of any direct connection. In the absence of any supportive archaeological evidence, a linkage between Atlantis and the Younger Dryas will have to remain a matter of faith rather than fact. Interesting but inconclusive.
Recent discoveries in northern Sudan of dozens of skeletons, the majority of whom were apparently killed by flint-tipped arrows, have led to the suggestion(e) they were the result of food shortages resulting from the Younger Dryas that in turn led to warfare over diminished food availability.

Rockall is an uninhabited islet in the North Atlantic, north west of Donegal in Ireland. It appears to have been first marked on a map in 1640(c). This ostensibly insignificant piece of stone is around 80ft by 100ft at the base and approximately
70ft in height. Nevertheless, its ownership is disputed by Ireland, Iceland, the Faroe Islands and the United Kingdom.
Rocabarraidh which was a mythic island referred to in the folklore of the Lordship of the Isles, a Scottish title, is generally accepted to be an early allusion to Rockall. The Atlantic rock is considered as part of the Hebridean parish of South Harris.
In June 1997, Greenpeace declared Rockall to be the independent state of Waveland(f).
Recently, a new claim has been made in connection with Rockall, namely, that it is a remnant of the Atlantis highlands, with the plain so vividly described by Plato, now situated under the sea to the south west of the rock. Two extensively illustrated French websites(a)(b) expound this theory. Which, however, are somewhat less than convincing. However, a 1938 newspaper report(d) suggests that a proposed linkage with Atlantis goes back much further!
In December 2016, Jonathan Northcote published 16.484ºW 58.521ºN, Atlantis, Found?, in which he offers spirited support for this location using a mass of geological data and underwater topography. He also suggests that Gades may have been Ireland. In January 2019, Northcote revised his book with additional material and published this second edition with the title of Atlantis, Found? An investigation into ancient accounts, bathymetry and climatology .
Stuart L. Harris, the prolific American researcher, has, in recent private correspondence with me, supported the vicinity of Rockall as the location of Atlantis, dating its demise to around 9577 BC.*He later expanded on this in a highly speculative paper published on the Academia.edu website.*
At the end of September 2018, the UK’s Daily Star, a well-known comic for adults, tried to revive the idea of Atlantis in Frisland(g) . They based their brief article on the speculations of Matt Sibson, presented as an ‘expert’, who admits that “there are still some questions that need clearing up.” I would like to know why Frislanders in the middle of the last Ice Age would want to attack a non-existent Athens 4,000 km away? If Sibson is considered to be an expert historian, my cat is a brain surgeon. Jason Colavito had a few words to add regarding Sibson’s pathetic claims(h).
Incredibly, a week later the same ‘newspaper’ cited Sibson again, this time claiming that Rockall was the remains of Atlantis(i), an equally silly idea that is not new.
Kevin A. & Patrick J. Casey have published a series of papers on the Academia.edu website outlining a globally catastrophic event that occurred thirteen thousand years ago, which they refer to as the ’13K Event’, but is more popularly known as the onset of the Younger Dryas period. In February 2019, they published Atlantis Revisited (j), in which they claim that Rockall was the location of Atlantis.
