The Moselle Shoals

Just north of Bimini, the Moselle Shoal (Moselle Reef) presents another supposedly mysterious site for divers to investigate. Lying at the same depth, 19 feet, as the Bimini Road, and approximately 5 miles further away to the northeast, Moselle Shoals is a jumbled collection of squared, granite "columns," resembling the collapsed ruin of a temple or public edifice of some kind, which some theorists insist are the remnants of a lost civilization called Atlantis. This manmade appearance is enhanced by a total absence of any other stones, megalithic or otherwise, on the sea bottom. At about 30 feet across and perhaps 200 feet long, the "ruin" approximates the dimensions and configuration of an elongated building.

Stone on Moselle Shoals northeast of Bimini

One explorer-author, Richard Wingate, has written "The Lost Outpost of Atlantis", in which he describes evidence of human engineering in the blocks. More significantly, he claimed that many of these blocks were not only regular in shape, with right angles and smooth surfaces, but that they also bore evidence of circular bore holes which regularly penetrated their entire width, depth or length for anything up to twelve feet. Strangest of all was his claim that some granite blocks possessed five-sided bore-holes which appeared to turn as they passed through the solid rock, rather like the barrelling of a rifle. Although the Moselle Shoals lies in the same waters with the Bimini Road, but the structures are wholly unlike one another, they may share a common Atlantean identity. However, some less sanguine theorists have concluded that the granite blocks are ballast from galleons.
