"In 2000, Paulina Zelitzki and Paul Weinzweig, owners of Advanced Digital Communications (a company that appears not to have a website), were one of four companies commissioned by the Cuban government to undertake sonar surveys off the Guanahacabibes Peninsula at the western tip of the island" (www.badarchaeology.wordpress.com, 2012, source).
It is 2,000+ feet deep.
And what they found was shocking.
To me, there is no way someone builds this underwater, and there is no way this city sinks and maintains so much structure.
As Graham Hancock discusses in various places, perhaps this finding drastically effects our historical timeline.
With much respect and curiosity,
