The Bimini Road, sometimes called the Bimini Wall, is an underwater rock formation near North Bimini island in theBahamas. The Road consists of a 0.8 km (0.50 mi)-long northeast-southwest linear feature composed of roughly rectangular to subrectangular limestone blocks. Various claims have been made for this feature being either a wall, road, pier, breakwater, or other man-made structure. However, credible evidence or arguments are lacking for such an origin.
On September 2, 1968, while diving in three fathoms (5.5 metres) of water off the northwest coast of North Bimini island, J. Manson Valentine, Jacques Mayol and Robert Angove encountered an extensive "pavement" of what later was found to be noticeably rounded stones of varying size and thickness. This stone pavement was found to form a northeast-southwest linear feature, which is most commonly known as either the "Bimini Road" or "Bimini Wall". After Valentine, the Bimini Road has been visited and examined by geologists, avocational archaeologists, professional archaeologists, anthropologists, marine engineers, innumerable divers, and many other people. In addition to the Bimini Road, investigators have found two additional "pavement-like" linear features that lie parallel to and shoreward of the Bimini Wall.
