I've seen
what I take to be the "Bimini Road" and am not too sure that it is not actually a natural formation. I've walked on it and once scared myself by stepping on a flounder. It comes right into the beach in front of Alice Town, but is in 10 or more feet of water further north, around Paradise Point.
Of course, I like Bimini alot, unlike other island vacation spots, there's nothing there to do except fish hard and drink hard, which is what people do and have done who go there, all the way back to Hemingway.
All the quirky histories, such as the "Bimini Road," the "Healing Hole," the "Fountain of Youth," the long history of smuggling, add to its weird, but compelling, tropical charm. With the brilliant turquoises and blues of the ocean and crystal clear water and sandy beaches, the Biminis are beautiful little islands.
The structures off western Cuba are at 2000+ feet. Do you think it's possible they could have sunk 1700 feet or so during a cataclysmic event and still retained enough integrity to be recognizable as man made centuries later? It's fascinating if they could, but I wonder. This location is very close to the ruins in the Yucatan.
