Lake Titicaca is the largest lake in South America and at over three kilometres is arguably the highest navigable lake in the world**, shared by Peru and Bolivia. In spite of claims to the contrary it is a fresh water lake, but is slowly reducing in size due reduced inflow from the retreating Andean glaciers. Lake Poopó to the south has now dried out completely(a).
***Karakul in Tajikistan exists at 4,000 metres and “is so salty, it’s almost impossible to navigate a boat on it without capsizing due to the vessel riding so far out of the water.”(e)*
To the south of the lake are remarkable archaeological remains of Tiwanaku and the equally exciting Puma Punku. Both sites have produced some extreme theories regarding the builders of these monuments, their technology level and the date of their construction. Arthur Posnansky, followed by Kurt Bilau have proposed a date of circa 9500 BC as the date of fall of Tiwanaku. There are also reports of pre-Incan structures submerged in Titicaca(d) .
South of Lake Titicaca, near Lake Poopó is Pampa Aullagus, a site identified by Jim Allen as the location of Plato’s Atlantis. While there is little doubt that advanced cultures existed around Titicaca, linking the region to Plato’s story is stretching credibility to its limits. I have already argued in respect of Jim Allen’s Andean theory, that the idea of an invasion of the eastern Mediterranean by an army from the west side of South America is untenable. That they would try it in reed boats like those of Titicaca is equally daft. Then, that this mighty army from ten regions of South America were defeated by the small city-state of Athens is just as laughable.
Equally questionable is the idea that there was a Sumerian presence around Titicaca, in relation to which Clyde Winters quotes(b) James Bailey as well as Ruth and A. Hyatt Verrill in supporting the idea that Lake Manu in Sumerian tradition was in fact Titicaca. The controversial(c) Fuente Magna bowl is also offered as evidence of this idea.
Pumapunku is a terraced earthen mound, faced with blocks and an important part of the Tiwanaku archaeological site on the Bolivian Altiplano. It has unique architectural features including the use of building blocks with up to 80 faces on them. The Tiwanaku site is pre-Inca and has given its earliest radiocarbon date as 536-600 BC and was in use until circa 1000 AD(a), which is a far cry from the flawed 12,000-15,000 BC date claimed by Posnansky(e)(f).
As with so many other enigmatic ancient sites, various members of the ‘lunatic fringe’ have attributed the construction at these location to either ancient astronauts or atlanteans or an exotic combination of both, based on either over fertilised imaginations or flawed data or again, both. Jason Colavito has written a critique of some of the more silly suggestions(b).
Ancient astronaut advocate Von Däniken[1147.221] and Brien Foerester(d) among others, have claimed that the stones of Pumapunku were composed of diorite, an exceptionally hard stone, which would have required a modern diamond-tipped drill to work it. The implication being that only Atlanteans with their advanced technology or extraterrestrials could have worked the stone with such precision.
However, Colavito and Michael Heiser(c) have pointed out that this identification is untrue and that in fact they were composed of the softer andesite and red sandstone. Apart from which, the Code of Hammurabi was incised on diorite, without Atlantean or extraterrestrial assistance, 2,000 years before the development of Pumapunku!
Javier Escalante Moscoso is an architect with a degree in archaeology who has extensively excavated and surveyed the Tiwanaku monuments.(see map above).
Heather Pringle “is a Canadian science writer who specializes in archaeology.” She has written many articles as well as a number of books and has her own website(a). Among her work is the prize-winning The Master Plan, in which she charts the work of the Nazi Ahnenerbe, founded by Himmler, “whose mission was to search for the lost civilization of an ancient master race.” Included in this fascinating book is an interesting account of the Hermann Wirth’s obsession with Atlantis in the North Atlantic as well as Edmund Kiss’ work at Tiwanaku in Bolivia.
*[A recent paper(b) by Pringle and Krista Langlois offers evidence that the Bering Strait during the last Ice Age was in fact a vast area of land the size of Australia and that it provided a crossing point, for humans and animals earlier and for longer than previously believed.
Pringle has also turned her attention to the Vikings in an interesting National Geographic article(c).]*

David Franklin Fasold (1939-1998) was an American marine salvage expert, who is best known for his book The Discovery of Noah’s Ark, in which he claimed to have identified the landing site of the Ark. However his location was not on Mount Ararat but Mount Masher Dagi some seventeen miles away. A critical review of his research is available online(a). This was not the only controversy with which he was associated. He was also involved in claiming that the Mount Sinai of biblical fame was not in the Sinai peninsula but further east across the Gulf of Aqaba in Saudi Arabia. The story is told in The Gold of Exodus by Howard Blum.
Fasold refers briefly to Atlantis in his ‘Ark’ book (p.298), where he cites a Portuguese tradition that “Atlantida, existed west of their shores.” He also mentions a southern Spanish belief that identified the Canaries as ‘Atalya’, which coincidentally is the preferred Atlantis location of Charles Berlitz, who wrote the Introduction to Fasold’s book. He also devotes some pages to discussing the possibility that Tiwanaku was a pre-Flood city (p.299).
Sean Bambrough is a New Zealand researcher of ancient mysteries. Since 1999 he has been developing a theory which places Plato’s Atlantis in the Andes and identifies its city as Tiwanaku. He has published 37 pages of notes in support of this contention(a)(c). A reader will find them tough going and at times repetitious, but it is clear that he has put a lot of study into the subject even if he has, in my opinion, produced a very flawed theory.
A number of researchers have assumed that when Plato referred to an ‘opposite continent’ he was referring to the Americas, however Herodotus, who flourished after Solon and before Plato, was quite clear that there were only three continents known to the Greeks, Europe, Asia and Libya [4.42].
Bambrough’s first major error is to equate the sinking of Atlantis with the uplifting of the Andes! The Andes are rising at a rate of some millimetres per year. and the geological evidence is that in the past the uplift rate was somewhat more rapid, which “in geologic terms, rapid means rising one kilometer or more over several millions of years.”(b)(e)
There is no evidence that the cataclysmic upheaval described by him could have occurred around 1400BC. He does not explain how these newly elevated mountains created muddy shoals that made the Atlantic impassable.
As I have already argued in respect of Jim Allen’s Andean theory, the idea of an invasion of the eastern Mediterranean by an army from the west side of South America is untenable. That they would try it in reed boats like those of Titicaca is equally daft. Then, this mighty army from ten regions of South America were defeated by the small city-state of Athens is equally laughable.
I could go on, but just a final couple of points; Plato never described Atlantis as a continent and Kircher’s speculative map depicts Atlantis quite clearly in our Atlantic Ocean between Spain and America.
Bambrough has recently updated his website(d), however, his writing style is as irritating as ever, in particular his excessive use of retronyms (forward slashes).
In 2017, he published(f) an extended ‘check-list’ which he feels supports his location theory. This offering is far too long and repetitious. It is clearly a triumph of quantity over quality.
In September 2020 Bambrough gave me a new link(g).

Tony Morrison is probably best known for his definitive work on the Nazca Lines, Pathways to the Gods. Tony and Marion Morrison have developed the South American Pictures.com website in order to show their extensive life-work. Unfortunately, the southamericanpictures website went offline but now, many of the image collections have been reassembled and are again available online(b).
In 1998 Morrison published a number of papers provocatively entitled The Bolivian Atlantis(b-e). They cover familiar territory – Tiwanaku, Pumapunku, Posnansky, Bellamy, Fawcett, Sykes, Blashford-Snell. This was the same year that Jim Allen published his Atlantis: The Andes Solution. Had Allen not done so, I suspect that Morrison might have produced a more detailed book himself as apparently he and a colleague, Mark Howell, had built up quite a dossier on the subject.
Surprisingly, Morrison did not mention the mysterious puquios of the Nazca region(f), which, with the aid of satellite imagery(g), have been shown to have been part of a sophisticated hydraulic system that supplied water to an extremely arid locality.
Belisario Díaz Romero (1870-1940) was a Bolivian businessman and polymath from La Paz. He had some ideas regarding race and evolution(a). that today would be considered odd, if not offensive. He believed that Tiwanaku had been built by a race of people he calls Homo atlanticus, who had come to America from Atlantis, situated in the Atlantic, over a landbridge from the east, over two hundred million years ago! (a)
His 1906 book Tiahuanacu is now freely available online(b).

Louis Pauwels (1920-1997) & Jacques Bergier (1912-1978) were the authors of the bestselling The Morning of the Magicians and its sequel Impossibilities Possibilities. Pauwels was the founder of the Planéte magazine and Bergier was a nuclear physicist. It is reported that Nostra magazine (20-26, April, 1977) carried an article by Bergier (real name, Mik Ezdanitoff)where he discusses the possibility of a Hollow Earth(a).
Their books rush from subject to subject like a train going from station to station without stopping long enough to pick up passengers. Uncharacteristically, they devoted quite a number of pages to Hörbiger’s strange lunar theories. This in turn led on to Tiwanaku that the authors refer to as ‘Atlantis of the Andes’ having great antiquity, but suggest that there was second Atlantis in the Atlantic that was destroyed later by “waters from the north”, which inspired the story of the Flood of Noah in the Bible.
Geodesy is usually defined as the measurement and mapping of the Earth. As a science, it is traced back to Pythagoras (6th cent. BC), who was thought to be the first to propose the sphericity of the Earth. Later, Eratosthenes (276 BC– 195 BC) was one of the earliest to attempt to determine the dimensions of our Earth and succeeded with remarkable accuracy.
A controversial aspect of modern geodesy is the claim that many ancient sites were deliberately established at locations that had a specific geodetic relationship to each other and/or the dimensions of the Earth. For example(a) in ancient Egypt, from Giza to the Equator is 1/12th the circumference of the Earth, Amarna to the Equator is 1/13th, Luxor 1/14th and Philae 1/15th! Graham Hancock in his Heaven’s Mirror pointed to similar relationships around the globe suggesting a possible world grid. This idea of a world grid has a number of supporters but is often classified as a ‘fringe’ interest due to the attempt by some to link gridlines with UFOs and their use of the grid as a power source(w).
Possibly related features may be the ley lines identified by Alfred Watkins in Britain(c)(g), the Alesia alignments in France discovered by Xavier Guichard(b) and/or the Heilige Linien of Germany claimed by Wilhelm Teudt(aa).
Heinz Kaminski had claimed to have discovered a megalithic grid system that stretched from Stonehenge across Europe with an east-west and north-south orientation and referred to as the Stonehenge/Wormbach System(h).
Even more exotic is the ancient Raetiastone navigation system rediscovered by Gerhard Pirchl (1942-2013) and outlined in a book by  Thomas Walli(ae).
Ashley Cowie has published a paper(ac) related to Alesia and the work of Guichard and others, as well as his own investigations.
I should also point out that Marcel Mestdagh also identified a form of a road system, laid out in giant ovals with radials in France. At the centre of these ovals was the ancient city of Sens. Philip Coppens informs us [1275.184] that a further strange discovery by Mestdagh was that this ancient road network, centred on Sens, was mirrored by a similar network of roads in England centred on Nottingham!
‘The Way of Virachoca’ in the Andes which runs through Tiwanaku and is oriented exactly 45° west of true north and runs for over 1000 miles, has been studied by Maria Scholten d’Ebneth  in the 1970s and expanded on by a number of Spanish speaking commentators and is now the subject of an article by Dave Truman(x).
In 1973, three Russians, engineers Valery Makarov and Vyacheslav Morozov along with Nikolay Goncharov, an artist, published in Russian an article with the eye-catching title of Is the Earth a Giant Crystal? (y) This was probably the earliest presentation of an earth grid based on ancient historical sites. A brief history of the earth grid theories that emerged around this time is available online(z). There is now a Russian geodesy website with an English translation(ab).
David Hatcher Childress published his Anti-Gravity and the World Grid  in 1993, with the modest claim that he “proves that the earth is surrounded by an intricate electronic grid network offering free energy.” Obviously, Childress’ understanding of ‘proof’ is different to mine, as the only proof required is the production of some of this free energy, which he has not done.
Tom Brooks has entered the fray with a study of 1500 prehistoric sites and his conclusion that the inhabitants of ancient Britain had a designed a navigation system based on a grid of isosceles triangles(i). Brooks has gone a step further and speculatively claimed that the accuracy of this geometry-based system could only have been designed through “extraterrestrial intervention”(r). This concept is explored more fully in his latest book, Seeing Around Corners: Geometry in Stone Age Britain  and in a series of video clips(s). A more critical view of Brooks’ ideas is also available on the Internet(j).
Some years ago a former employee of a NASA sub-contractor, Maurice Chatelain claimed that within a 450-mile radius of the Aegean island of Delos that 13 mystical sites, when connected by straight lines formed a perfect Maltese Cross(u)!
Others such as Livio Stecchini(d) and Jim Alison(e) using geodetic calculations have identified São Tomé and Cape Verde respectively as the location of Atlantis. I must also include Hugo Kennes, a Belgian researcher with a passionate interest in global grids and sacred geometry(l). Kennes has also informed me of a new Facebook group(q) deal with all aspects of the subject, as well as another(v) that includes submerged cities and other features.
Anyone interested in pursuing a study of this subject might like to look over James Q. Jacobs’ archaeogeodesy website(f) as well as the BioGeometry website (m).
If you have pursued all the links so far, you can pamper yourself further with a paper(k) by William Becker and Beth Hagens(n). Another researcher in this field is Dan Shaw whose website(o) gives a good overview of the subject.
Jean-Pierre Lacroix added his weight to the debate with his 1998 paper entitled The Mapmakers from the Ice Age(t).
A global network of sacred sites was also put forward by Rand Flem-Ath & Colin Wilson in The Atlantis Blueprint . This book was intended as a sequel to When the Sky Fell , but generally wandered off into other areas after the first couple of chapters.
I am somewhat sceptical about certain aspects of geodesy, particularly some of the claims of a world grid. However, it does raise many questions that require further study and explanation. In this connection, I would recommend John Sase’s Curious Alignments  as a good starting point. He confirms the work of Guichard and also offers a range of his own discoveries in the Great Lakes region.
In February 2020, Frank Maglione Nicholson, Ken Phungrasamee & David Grimason, collectively known as The Nazca Group(ad), published The Nazca Great Circle Map Hypothesis. Their claim is that “The lines and geoglyphs carved into the Nazca plateau represent a map of the Earth. The map is a Great Circle Map: a gnomonic projection with the center of the Earth as its cartographic view point. Each line on the Nazca Plateau represents a great circle of navigation centered at the center of the Earth and encircling the entire planet. The majority of the lines on the Nazca Plateau radiate from five loci of origin called radial centers.” I found this rather esoteric proposition difficult to absorb.
>Arturo Villamarin has published many books  and papers(af)(ag) in which the geometry and astronomy of archaeological monuments; Göbekli Tepe, Stonehenge, Teotihuacán and Mohenjo Daro, among others, are discussed.<

Americo Huari Román (1950 – ) is a Peruvian electrical engineer who was born in the former Inca capital of Cuzco. He is the author of La Atlantida y el Imperio de los Incas (Atlantis and the Empire of the Incas). This is a bilingual book with a somewhat flawed English translation.
He contends that originally Atlantis had been an island in the Atlantic from where their influence spread to the the cultures of Europe, Africa and South America.Huari enters the realms of speculation with the wild claim that the Atlanteans used some form of levitation using anti-gravity fields! At the same time he also claims that they did not have the wheel as they did not need it! He quotes Blavatsky and other theosophists and psychics, which is probably where he got his ideas of advanced technology in Atlantis that is comparable with our own.
Even more disappointing for me was Huari’s failure to address Plato’s account, in particular the control of the Western Mediterranean by the Atlanteans from North Africa northward as far as modern Tuscany, and does not adequately explain the war with Egypt, if, as he claims[p.211] it was already an Atlantean colony!
Before the Great Deluge, Huari claims that most of central Brazil had been a huge inland sea and that Atlanteans and Arawaks lived around this lake and that one artifact left by them is the enormous carved Ingá Stone(c).
After the Deluge a cataclysm inundated Atlantis and Brazil rose 100 metres, which got rid of the inland sea. Some groups fled to the Andean highlands of Peru, eventually developing the Empire of Tiwanaku which later morphed into the Incan Empire.
Huari supports his views with a number of video clips (a) which unfortunately are only in Spanish. Huari published a new video(b) in July 2014.
