This documents the work of an English cartographer/satellite photo interpreter named Jim Allen - who has taken the two dialogues that Plato wrote about Atlantis literally. He has used modern technology and his understanding of ancient measurement systems to locate and area of the world that he believes matches Plato's physical descriptions of Atlantis. In a nutshell, he places the capitol of the empire in Bolivia - and he believes that the entire continent of South America is, in fact, Atlantis. While honestly, it's hard to believe he has actually found it (as I think Plato was writing metaphorically about how great Greece could have been if they had maintained the pursuit of virtue - instead of succumbing to greed) - he does have an interesting theory - and he has found some remarkable evidence to strengthen his claim.
"Atlantis In The Andes" was premiered Friday, June 22, 2001 on The Learning Channel. It is due to be airing on TLC in the UK next February. It seems that they will also be offering it for purchase on VHS sometime in the near future.
