Johan Nygren is the author of a number of papers touching on a number of subjects such as expansion tectonics(b), Cro-Magnons and Atlantis. He brings them all together in an Atlantis theory which places Atlantis in the region of Iceland(a). He believes that Cro-Magnon man lived in Atlantis(c). However, in another paper, he claims that Greenland looks like the map of Atlantis created by Athanasius Kircher(e), a suggestion put forward some years ago by Dale Huffman.
When Nygren first wrote about Atlantis, in an article now removed from the internet(d). he was sure that it could be identified as South America,
He also proposes that Atlantis produced the beginnings of civilisation.
(d) Having discovered the myth of Atlantis in the past days, I’ve now conformed to that it described South America (“Isla Atlantica”) — SteemKR (archive.org) (link broken)
