The Younger Dryas Impact Hypothesis (YDIH) is based on the claim that around 12,800 years ago the Earth had an encounter with a very large asteroid or comet that broke up in an airburst over North America and of which some fragments possibly hit the ground directly(a).
Many effects that have been linked with this event with varying levels of enthusiasm including a suggested association with the demise of Atlantis. Elsewhere, megafaunal extinctions, cataclysmic floods, the disappearance of the Clovis people and the creation of the Carolina Bays(g), have all been proposed as consequences of this episode.
In 2006, Richard Firestone, Allen West & Simon Warwick-Smith published the foundations of the YDIH in The Cycle of Cosmic Catastrophes . A year later the hypothesis had a more public airing at the American Geophysical Union Press Conference, Acapulco, Mexico, May 23(d). This was followed the same year by the publication of a formal paper in the Proceedings of the National Academy of Sciences of the United States of America(f).
Since then volumes have been written on the subject, both pro and con(c).
A 2014 paper(h) 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(f) from Megan Gannon.
December 2014 saw Graham Hancock raising the issue of a cometary cause for the Younger Dryas and its possible association with ancient Egypt(e).
Dr Michel-Alain Combes (1942- ) is a French amateur astronomer with a PhD in astronomy from the Université Pierre et Marie Curie (Paris VI). For forty years he has studied impact catastrophism and published his views in his book, La Terre Bombardée (The Bombarded Earth). His extensive website(a) endeavours to combine history, myth and science and includes a reference to Atlantis, as well as a kind mention of this site. His book can also be read on his site (French).
Combes delivered a paper in English(b) to a 2008 Conference in Paris entitled; The Apocalypse of the Year 10,000 BC – Myth or Reality? It has been proposed that this event may have created the Carolina Bays and destroyed Atlantis as proposed by Otto Muck.
Furthermore, it has also been linked to the onset of the mini ice age known as the Younger Dryas as described by Firestone, West and Warwick-Smith in their book The Cycle of Cosmic Catastrophes.
In 1992, Asteroid ‘3446 Combes’ was named in his honour.

Trevor Palmer (1944- ) is an English Professor of Biology now living in Scotland. Apart from his day-job of enzymology and the study of genetic disorders, which led to an interest in evolution, which in turn brought him to research catastrophism, he has written a number of books on these subjects, including Perilous Planet Earth, which places today’s “concern about the threat to Earth from asteroids and comets within an historical context.” He devotes two chapters of this comprehensive work to the subject of Atlantis, in which he reviews (chap.13) some of the late 19th and early 20th century theories as well as more recent developments (chap.28) exposing many of the weaknesses in the arguments on offer.
While Palmer does not express any personal views on the subject, it is noteworthy that he wrote an introduction to the 2005 Barnes & Noble edition of Lewis Spence’s The History of Atlantis. After a brief look at Spence’s life, Palmer gives an overview of the principal strands of Atlantology today and concluded that many of the issues debated 80 years ago are still unresolved and for that reason Spence’s book continues to be worth studying.
Palmer wrote a short paper(a) in 1987 which he was cautiously sceptical of the Atlantis story, particularly the possibility that it was destroyed during the Late Pleistocene era, with which I concur. He also touched on the subject of the Carolina Bays, apparently adding support to the now discredited idea that they were created by wind action. I expect that he may have modified his views by now.
Palmer addressed the Society for Interdisciplinary Studies (SIS) in 2004 on the background to his book, published the previous year(d).
Palmer has written two papers(b)(e) on the history of catastrophism from the time of Velikovsky and the ensuing debates, until the present, when catastrophism has greater acceptance and which now offers a variety of competing of ideas regarding the number, source, date and consequences of specific catastrophes.
Palmer has also written a 2018 review(c) of Perilous Planet Earth in the light of developments since it was first published.
>Palmer and Gunnar Heinsohn have been debating Heinsohn’s claim that our chronology of the 1st millennium AD is deeply flawed, on the Q-Mag website(a). Palmer has also written a lengthy paper supporting his views(a).<

R. Cedric Leonard (1934- ) is from Oklahoma and has worked as an electronic technician, initially in the U.S. Navy and later in private industry, from which he retired in 1990. He has studied Comparative Religion, Sanskrit and Classical Greek and has a B.A. in Anthropology from the University of Oklahoma. He is also self-taught in Egyptian, Canaanite and Phoenician inscriptions. He has also speculated on the possibility of the Phoenician alphabet having its origins in Atlantis and possibility of a connection with the Glozel Tablets(c).
His Sanskrit studies led him to investigate stories of the vimanas or ancient Hindu flying machines. He has produced several booksand scientific papers on the subject of Atlantis and ancient India. He has also written on the existence of UFO’s in ancient Egypt(d), Mesopotamia(h) and the Bible, particularly the Book of Ezekiel(e). He has also produced a paper(f) about archaeological mysteries in general.
Although retired, he still maintains his very interesting Atlantis website(a), which covers a range of subjects including connections between Cro-Magnon Man and ancient Egypt with Atlantis. Unfortunately, his website has now (2019) gone offline.
He locates Atlantis along The Mid-Atlantic Ridge and offers geological, mythological, linguistic and paleontological evidence to support this idea and for its destruction following worldwide catastrophes around 10000 BC. He has also written a paper(g) on the asteroid/comet impact around the same time, which created the Carolina Bays and its possible connection with the destruction of Atlantis. This encounter was brought to the notice of a wide audience by Richard Firestone and his colleagues by their book, The Cycle of Cosmic Catastrophes.
Leonard himself recognises that his belief in prehistoric flying machines may lead some readers to dismiss his carefully thought out theory on Atlantis, but he is adamant that both existed. Nevertheless, it is fair to say that Leonard is one of the few writers on the subject who has produced original material to support the idea of Atlantis’ existence.
Some of Leonard’s work can be found plagiarised on the Internet, most blatantly by the artist, Charles Alexander Moffat(b).

Richard Firestone together with his co-authors Allen West and Simon Warwick-Smith have written one of the most impressive accounts of a cosmic collision that led to the extinction in North America of large mammals such as the mammoth and sabre-toothed tiger and the concurrent disappearance of the Clovis people at the end of the last Ice Age.
>Before what has become known as the Younger Dryas Impact Hypothesis (YDIH) was formulated, Firestone and William Topping speculated that North America was impacted by intense cosmic rays from a supernova in a 2001 paper entitled Terrestrial Evidence of a Nuclear Catastrophe in Paleoindian Times(l).<
The YDIH also offers a credible explanation for the Carolina Bays. However, they propose that this collision had catastrophic global consequences. The three scientists are prepared to consider the possibility that Plato’s Atlantis story, however garbled, is related to the same episode[0110.328]..
Since the publication of their book some evidence(a)(k) has emerged that would appear to conflict with their core thesis. This criticism appears to be gaining support according to a May 2011 report(b)(d). However, in September 2012 it was reported that further intensive investigation has revealed flaws in the evidence gathering of Firestone’s critics(f). The interdisciplinary team of scientists from seven U.S. institutions concluded that “a disregard of three critical protocols, including sorting samples by size, explains why a group challenging the theory of a North American meteor-impact event some 12,900 years ago failed to find iron- and silica-rich magnetic particles in the sites they investigated.”
Strong resistance to the Firestone claims continued into 2013 when the Royal Holloway and the Sandia National Laboratories along with 13 other universities across the United States and Europe mounted further challenges(g).
The waters were muddied further when it was revealed that Allen West was formerly known as Allen Whitt, who was convicted in California of posing as a state-licensed geologist(b) and fined $4,500! He legally changed his name in 2006. His respected co-authors were apparently unaware of his history and as a consequence of West’s central role in the data gathering, the hypothesis is considered by some to be tainted. This may be a case of shooting the messenger instead of the message, a view discussed at length on the Internet(e).A spirited defence of both West in particular and the theory of the team in general has also been written(c) and should be read in order to get a more balanced view of this particular controversy.
The core debate has rumbled on ever since. In July 2015 the University of California, Santa Barbara, released the results(h) of research, led by James Kennett, which again supported the impact theory and “has narrowed the date to a 100-year range, sometime between 12,835 and 12,735 years ago.”
The battle has continued, apparently inconclusively, with more papers being published by all sides. July 2018 saw an update of the controversy published on the Science News website(i), with no sign of the war ending.
Nevertheless, in late 2019, further evidence has emerged that appears supportive of Firestone’s theory. Where previously nanodiamonds were an important feature in the presentation of his ideas the latest studies focus on platinum as an important marker(j).
Inspiration resulting from an interview with Firestone led Kevin Curran to a study that ended with the publication of Fall of a Thousand Suns, in which he investigates the effect of extraterrestrial encounters on the development of early religious beliefs.
Andrew Collins was born in England in 1957. Over the past twenty years he has been investigating the possible existence of ancient advanced civilisations. He has written three books on the subject of pre-history. His volume on Atlantis has been well received as an example of how the subject should be researched. Although Collins initially thought that Antarctica had been home to Atlantis, he eventually concluded that Cuba was its location and provided a wealth of evidence to support this view in his book, Gateway to Atlantis. David Rohl, wrote a sympathetic Introduction for the book and repeated and expanded on his expressed views at a subsequent lecture(h).
Collins also wrote of why his chosen Cuba is a better candidate for the location of Atlantis than the Bahamas(r).
Collins has recently written another controversial book, on the place of the constellation Cygnus in prehistoric consciousness. Arising from this study, it appears that the position of the Cygnus stars correlate more accurately with the Giza pyramids than those of Orion, which was proposed some years ago by Robert Bauval. Incredibly, a fifteen-year-old Canadian boy has produced a comparable theory(e) involving Mayan cities and a star map. The site proposed by him has now been identified, by people who personally know the location, as either an abandoned cornfield or a marijuana crop(f). In 2018, Gustavo Muniz posted a number of videos on YouTube suggesting an Orion connection with a site in the Amazon Basin(i)!
However, Collins has not been completely seduced by Bauval’s discovery and prudently remarks that the correlation may be just coincidence. Jason Colavito has written a brief critique(b) of this book.
In 2007, he wrote an article(q) for Alternate Perceptions Magazine reviewing the comet impact theory of Richard Firestone et al and its possible implication for his Atlantis theory.
In 2005, Collins published The Cygnus Mysteryin which he explored the significance of the Cygnus constellation in the ancient cultures of America, Egypt and Britain. Furthermore, in August 2013 he published a paper(c) with Rodney Hale suggesting that the Göbekli Tepe site is probably aligned with the star Deneb in the Cygnus constellation. This idea has now been expanded on in Collins’ 2014 book, Göbekli Tepe: Genesis of the Gods, although his treatment has been heavily criticised as pseudoscience(g).
Collins has made some dramatic claims regarding the significance of Cygnus including the proposal that “The veneration of Cygnus as a bird associated with cosmic life and death goes back 17,000 years to when the constellation occupied pole position in the northern night sky” and perhaps even more extreme, the idea that “Cygnus is at the root of all the world’s religions.”
Collins continues with the Cygnus-Giza connection in a subsequent offering Beneath the Pyramids. This book reveals the tunnels and chambers beneath the Giza pyramids and their possible connection with the “Hall of Records” predicted by Edgar Cayce to be located there and due for discovery.
In a paper(d), co-authored with Rodney Hale, published in April 2016, Collins returned to the theory of a Cygnus-Giza correlation based on a master plan that they claim can now be demonstrated mathematically.
Collins has now moved on to new ground with his Lightquest, in which he attempts to offer a new explanation for the UFO phenomena. He claims that what have been described as UFOs are “the product of sentient light forms and light intelligences that co-exist with humanity, and have done so since time immemorial.”
Nevertheless, Collins returns to the subject of Atlantis with a new book, Atlantis in the Caribbean, which is a revised version of Gateway to Atlantis. In it he follows some of Otto Muck’s ideas and “Explains how Atlantis was destroyed by a comet, the same comet that formed the mysterious Carolina Bays“.
When the Denisovans were recently identified as an extinct species of hominid, related to the Neanderthals It did not take long for speculative history enthusiasts to jump onboard this new bandwagon. Andrew Collins has now published The Cygnus Key, in which he claims to present “compelling evidence showing that the earliest origins of human culture, religion, and technology derive from the Denisovans, the true creators of the lost civilization long known to exist but never before proved.” Jason Colavito also presents a critique of this latest ‘Cygnus’ book in a two-part(m)(n) offering.
While the first Denisovan remains were found in Siberia, there is now evidence that they were also the earliest hominins on the Tibetan Plateau (j)
Prior to the identification of the Denisovans, Colin Wilson had claimed that the Neanderthals “were the civilising force behind Atlantis”! One cannot help wondering if another early hominid species is discovered, which is quite possible, will they also be claimed as the progenitors of this ancient lost civilisation?
In this new book Collins also “explains how the stars of Cygnus coincided with the turning point of the heavens at the moment the Denisovan legacy was handed to the first human societies in southern Siberia some 45,000 years ago, catalyzing beliefs in swan ancestry and an understanding of Cygnus as the source of cosmic creation.” Hmm.
In June 2019, Collins published a two-part article(l) on the Ancient Origins website, in which he explores possibility of Giza’s Great Pyramid has sound technology incorporated into its construction and that “its Dead-end passage function as an infrasound generator?”
Later in 2019, Collins had his 1996 book, From the Ashes of Angels, banned in Turkey(p), it is not clear yet if he is personally banned as well. Apparently it all stems from some perceived support that Collins gave to the Kurdish cause! I hope he refrains from mentioning the Armenians.
Andrew Collins maintains a useful website(a) that has plenty of information on his books and lectures. He also offers an extended section relating to his Atlantis theories(o).
Catastrophism today is the name given to a school of thought that supports the idea that the history of the Earth has been punctuated by natural events such as floods, fires and asteroid strikes that have caused widespread if not global devastation and that some of these events occurred within the memory of man and are recorded in worldwide mythologies.
Georges Cuvier (1768-1832) is sometimes referred to as ‘the father of paleontology’ and an early exponent of catastrophism.
Worryingly, it is now more generally accepted that further catastrophes will occur as a result of future cometary/asteroidal strikes. One such close encounter, around 2800 BC, was considered by the Christian catastrophist, Donald W. Patten, to have generated the Deluge of Noah(j) and was the source of the flood legends found around the world! Patten nominates Mars as the intruder(l), an idea also advocated by Elsar Orkan, who, however, proposes a date of around 8000 BC for this encounter.
Some readers may think that the subject has no direct connection with Plato’s Atlantis, however, his text refers to a number of catastrophic events that clearly brought devastation to Athens, Atlantis and beyond. The Flood of Deucalion and earlier inundations, Phaeton and other cosmic encounters, plus conflagrations and earthquakes all point to periods of great instability in the early prehistory of the Aegean region and quite probably much further afield.
Jürgen Spanuth devotes chapter 4 of his Atlantis of the North to an examination of “the natural catastrophes of the 13th century BC” that deals with Phaeton and the blizzard of floods, earthquakes and eruptions that beset the Eastern Mediterranean at the end of the 2nd millennium BC. Some of these matters have been recently expanded upon by Nur & Cline(f)(g) and endorsed by Stavros Papamarinopoulos[0750.73].
August 2013 saw studies published(h) which pointed the finger at climate change as the cause of the widespread political instability in that region during the second millennium BC.
Claude Schaeffer, a celebrated French archaeologist, declared in 1948 that on at least five occasions during the Bronze Age the Middle East had been subjected to widespread catastrophic destruction as a result of natural events rather than human activity.
Immanuel Velikovsky is arguably the best know of the 20th century catastrophists, who published two books in the 1950’s that provoked widespread controversy that continues today. There is an interesting albeit a sceptical review of catastrophism in the last century by Patrick Moore & Bob Forrest in Chapter 14 of More Things in Heaven and Earth(k).
Paul Dunbavin, author of Towers of Atlantis , has published a paper(n), highly critical of Velikovsky’s work.>Dunbavin has researched the evidence for a number of pole shifts that are not dependent on what he describes as the “naïve astronomy” of Velikovsky.<
In 1964, the Belgian mathematician René Gallant (1908-1985) published Bombarded Earth which dealt in great detail with the consequences of meteorite impacts with the earth. Gallant, perhaps because of his amateur status as a geologist, never received the attention he deserved.
More recently Allan & Delair produced another book that identified 9500 BC as the date of a global catastrophe following an encounter with a comet. Their conclusions are at variance with Velikovsky’s, particularly regarding dates. Professor Mike Baillie of Queens University, Belfast is a well-known dendrochronologist who has recently entered the debate with his book, Exodus to Arthur that adds evidence from his discipline to support the theory of cometary or asteroidal impacts with the Earth. Unfortunately his work is confined to the last 4,500 years and so casts no further light on the 9,500 BC date apart from offering support for the possibility of extraterrestrial impacts.
However, Richard Firestone and his co-authors have researched an impact ‘Event’ the occurred 13,000 years ago and caused devastation in North America including the creation of the hundreds of thousands of Carolina Bays and some of the outbursts of Lake Missoula. Like Baillie, they claim that a memory of this event has been preserved in the folktales of many of the North American Indians. This book is a must-read for anyone interested in the latest developments in catastrophist research.
The destruction of Atlantis has been linked to a number of possible catastrophic events including earthquakes, volcanic eruptions, floods and asteroid strikes. Plato’s account cites a flood as the immediate cause of the disappearance of Atlantis. In the 18th century Giovanni Carli was probably the first to link a cometary encounter with the Earth as the cause of Atlantis’ demise. This idea has been supported by numerous writers ever since, with Emilio Spedicato being one of its leading exponents today.
There are numerous sites on the Internet relating to catastrophism of which one(a) can be recommended as a good starting point for further study. Andy Blackard has listed(b) events connected with global upheavals around 3200 and 2000 BC. An Australian archaeologist, Peter Jupp, is the creator of the Ancient Destructions website(e) which deals with a number of historical mysteries including, Baalbek and Antarctica.
A more recent book by Robert Argod postulates that many of these historical catastrophes were caused by an irregular series of accelerated tectonic movements, although he does not offer a credible mechanism to explain the triggering of such upheavals. Is it possible that the strikes by or near misses with extraterrestrial objects, proposed by so many, generated the tectonic shifts proposed by Argod?
Professor Trevor Palmer has written a comprehensive history of catastrophes and catastrophism from the earliest times and its relevance today. His Perilous Planet Earth includes a couple of chapters in which he reviews Atlantis theories in the context of catastrophism.
Dr Michel-Alain Combes has a PhD in astronomy from the Université Pierre et Marie Curie (Paris VI). He has an extensive website(i) dealing with catastrophism, which translates quite well.
2012 was been promoted as the date of the next worldwide catastrophe based on a highly questionable interpretation of the Mayan calendar. New Age gurus were promising a change in global consciousness, whatever that means. If interested you can read more of this nonsense online(c) or consider a more balanced view(d).

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)

Atlantis of the North  was the third book written by Dr Jürgen Spanuth on the subject of Atlantis. His first book published in German, led to court action by Spanuth after being labelled ‘a peddler of lies’. The matter ended when his detractors, ten professors, admitted that their objections to his work were groundless.
Spanuth’s book controversially locates Atlantis in the North Sea near Helgoland and attributes its destruction to the consequences of widespread natural catastrophes that the world experienced in the 13th century BC. These disasters led to large-scale migrations, one of which was from Scandinavia into the Mediterranean where Spanuth insists that the migrants were known as the ‘Sea Peoples’, or as he calls them ‘North Sea Peoples’ and portrayed on the walls of the temple of Medinet Habu. He claims that there is considerable agreement between Plato’s Atlantis story and the carvings at Medinet Habu.
Furthermore, Spanuth identifies a cometary impact with the Earth as the cause of these upheavals. He claims that this impact is preserved in mythology as Phaëton by the Greeks and others as Typhon, Sekhmet, Anat, and Tistrya etc. Incidentally, the Carolina Bays visible today have been linked with this event.
It has been pointed out that much of the material used by Spanuth seems to have been drawn from the research archives of the Nazi Ahnenerbe-SS. The result is a closely argued work that is worth reading, however unacceptable the Heligoland location is now seen.
In 2015, Spanuth entered the world of controversy again when The Mystery of Atlantis Unravelled was published by Amazon’s self-publishing department, CreateSpace, with a new title The Mystery of Atlantis and the author’s name changed to ‘John Lock’! This is simply a badly scanned copy, blatant plagiarism and possibly breach of copyright as Spanuth only died in the 1998!
Gateway to Atlantis  by Andrew Collins is one of the better books on the subject. It is a fully indexed and referenced work that clearly indicates the effort and depth of research that went into producing it.
Collins was originally inclined to believe that the Antarctic had been the home to Atlantis but has gradually come to focus his attention on the Caribbean. He has trawled the classical writers for any possible reference to Atlantis and has concluded that all their considerable evidence points to the Atlantic and in particular the Caribbean as the location of Atlantis.
In order to explain the sudden destruction of Atlantis, Collins discusses the possibility of some kind of cometary or asteroidal impact being the culprit. He is inclined to see the Carolina Bays as remnants of this collision. His conclusions are closely mirrored by the views of Emilio Spedicato. More details can be found on Collin’s website(a).
