Underwater Cuban Discovery
In July 2000, using sophisticated side-scan sonar equipment, researchers detailed clear images of symmetrically organized stone structures that resembled pyramids, roads and buildings. It appeared to be extensive series of structures over several miles. Later, images sent back by a ROV confirmed the presence of large, cut granite-like blocks in perpendicular and circular formations; some in the shape of pyramids, with many blocks stacked one stop another. There is no granite in that region of the Caribbean, only limestone.

The Andros Platform
This discovery is of a gigantic, three-tiered stone platform just off northern Andros Island in the Bahamas. It was found in 2003 by a diving team doing research on underwater features. The platform consists of three tiers with an area measuring about 400 yards long and 150 feet wide. Each tier starts with a row of large blocks, almost square, measuring about 10 by 8 meters.

The Bimini Road
This is a formation of an extensive pavement of flat stones found 500 yards offshore of Bimini Island in the Bahamas. The Binimi Island is 50 miles east of Miami and about 100 miles north of Andros Island. The formation is made by thick, mostly rectangular blocks of stone lying on the sandy bottom.
