This site, perhaps built by a culture that far pre-dates the famous Maya of the Yucatan Peninsula, might have been the victim of a vast, mysterious cataclysm that somehow dropped it 2,000 feet beneath the surface of the sea.
"Nothing is known for certain now," Weinzweig said, "but oral tradition in early Mexico speaks of an advanced civilization of tall white people who came from the East, and of an island that sank in a great natural disaster." In the ancient language of some early Central American Indians, he said, "the word Atlanticu means 'our good father,' or, 'the place where our good father rests.' "
Then again, maybe not.
Maybe the intriguing shapes found by the sonar are just that -- intriguing shapes, carved over the centuries by whimsical Mother Nature.
Images sent back by the ROV confirmed the presence of large blocks of stone -- about 8 feet by 10 feet -- some circular, some rectangular, some in the shape of pyramids. Some blocks appeared deliberately stacked atop one another, others appeared isolated from the rest.
Could it be that the Caribbean Sea has a similar geological history as the Mediterranean Sea? That is, could the Caribbean Sea have been a dry basin, and could it have been so during the existence of anatomically modern man? Having performed an exhaustive search on the topic, I couldn't find a single source within the alternative literature let alone a peer-reviewed scientific paper that put forth such a hypothesis. However implausible this hypothesis may be, if true, it would provide a simple and elegant solution to the problem discussed, namely that of how a city could have been built close to 700 meters (2300 feet) below sea level today, or 580 meters (1900 feet) below sea level even during the maximum drawdown of the world's oceans. If the Caribbean Sea simply did not exist for an extended period of time in the human past, a reasonably advanced civilization inhabiting the area could have built cities on dry land thousands of feet below sea level, even over ten thousand feet below sea level.
