Greenland was first proposed as the location of Atlantis in the 17th century by François de la Mothe le Vayer. More recently some of the more imaginative writers have tried, unsuccessfully, to revive interest in this idea. One of these is the American, Dale Huffman, who claims that the outline of Greenland is comparable with Kircher‘s famous map of Atlantis. He has also proposed that while Atlantis primarily consisted of Greenland it also included “the islands of the United Kingdom and Iceland”(h). Huffman ignores the fact that Kircher’s map clearly places Atlantis between the Strait of Gibraltar and America, not between Canada and Scandinavia. Apart from this, Kircher favoured the Azores and Canaries as the remnants of Atlantis.
Another proponent is Mario Dantas who is equally determined to link Plato’s description with the enormous island of Greenland(a) and has submitted a paper on the subject to the 2008 Atlantis Conference in Athens.
Another site(b) advocates the Baffin Basin just west of Greenland, as the Great Plain of Atlantis. This idea developed by a New Zealander, Ian Fox, is based on a reinterpretation of Plato’s text combined with the studies of Charles Hapgood.
In 2014, Antonio Usai published an English translation of his 2011 booklet on the Pillars of Hercules in which he places the original ‘Pillars’ on the Tunisian island of Kerkennah and then unexpectedly proposed that Atlantis was situated in Greenland.
Another proponent of the Greenland location is Stefan Grossmann in his book, Atlantlantean(sic) Philosophy(d), a commentary on the non-existent ‘Emerald Tablets of Thoth’(e), concocted by Maurice Doreal (Claude Doggins).
In October 2011 a team of researchers from the Laboratory of Geology in Lyon may have elevated the importance of Greenland to an even higher level with their claim(c) that life on earth may have originated there 3.8 billion years ago.
In 2013, Lucio Russo, an Italian mathematician and science historian, located Thule on the coast of Greenland, having identified errors in Ptolemy’s geographical calculations.
In 2014 Antonio Moreno Checa published La Atlántida. El mito hecho realidad (Atlantis. The myth comes true)  in which he also locates Atlantis in Greenland. Gennaro Anziano, an Italian writer, has also located Atlantis in Greenland(g) in his 2001 book, Atlantis – Discover the land of the gods.
David Chase Taylor, journalist and conspiracy theorist, published, Greenland Theory: Apocalypse Now, which placed Atlantis in Greenland. However, he is more concerned with the location of the CIA, which he continually repeats has its headquarters under CERN in Switzerland(j)!!! An April 2020 review gives a flavour of the wide-ranging nonsense to be found within this book(k), with little to advance our knowledge of Atlantis.
Leaving aside any suggested connection with Atlantis, there are other features of the vast island that deserve attention. There are a number of raised beaches which clearly indicate that “the whole of this large island has been raised, or the sea has sunk, in post-glacial times” and that “the upheaval has been greater in the north”. Their height above sea level varies from 325 and 480 feet!
In 2018 a huge impact crater was discovered under Greenland’s Hiawatha Glacier. It was initially thought that this impact had been the cause of the Younger Dryas cooling 12,000 years ago, but this idea has now been discounted as the crater is now thought to be 58 million years old.
