Lake Izabal is the largest lake in Guatemala and nominated by at least two ‘researchers’ as the location of Atlantis. Duane K. McCullough has been a supporter of the Guatemalan site for a number of years(a). His views(b) are contained in his book, Spirit of Atlantis.
An even more colourful advocate is the retired German schoolteacher, Joachim Rittstieg. On March 1st 2011 it was reported(c) that an expedition, sponsored by the German tabloid newspaper, Bild, and led by Rittstieg headed for Guatemala in search of the gold. Unfortunately all they found was a pot(e), following which Rittstieg managed to declare the expedition a ‘success’(d). Rittstieg has combined information he has gleaned from the Icelandic Eddas, Plato, Mayan calendars as well as oral sources and concluded that the capital of Atlan can be found submerged in Lake Izabal in Guatemala along with over 2,000 gold tablets(f).
The indefatigable Erich von Däniken(g) has added some support for Rittsteig’s claim of a sunken city in Lake Izabal although commenting that the treasure there is not gold, “just engraved messages from the past”!
