My first question was... was there significant enough geological transformation to sink a civilization a half mile into the gulf over the last several thousand years?

Also, I'm surprised that DOS wouldn't allow it so close to Fidel... isn't Froggy Bottom stuffed with xlinton holdovers?

"My first question was... was there significant enough geological transformation to sink a civilization a half mile into the gulf over the last several thousand years? "

Yup. The end of the Ice Age.

My theory: During the Ice Age the Gulf Of Mexico became blocked off from the oceans of the world when they were 300-500ft lower than they are presently. During that time of blockage, the Gulf Of Mexico dried up to become a large lake and someone build a city on the coast of that lake.
Then the ice melt from the Ice Age caused the world's oceans to rise, the 'dam' was breached and the 'lake' became a gulf again and now we have a city 1/2 mile under water. This happened to the Black Sea (Noah's Flood?) and some say to the Mediterranean also. (Probably a lot of other places around the world too)

Here is a map of the world's oceans with the water level reduced by about 300ft. Now, Imagine that map with the water level reduced by 500ft. Interesting things begin to happen around Cuba, Bahamas and the Yuchatan.
