The Great Islands Under The Sea

Under-water limestone caves in the Bahamas - the famous Blue Holes - contain
stalagmites and stalactites and usually connect through caves to deep water -
a cogent proof that they were formed above sea level. 

An additional indication of cataclysmic events having occurred in the area is the
position of some of these formations - not straight, but tilted and broken, as
though they had descended not gradually, but precipitously, into the sea.

An examination of the oceanic depth contours off Yucatan and the islands of the
South Caribbean suggests that another extensive land area existed north of Vene-
zuela and East of present Central America.

It is from Yucatan and Belize that ancient Mayan roads continue out from the
coast to destinations now under the sea.  North of Venezuela, an undersea wall
extending for at least one hundred miles, was judged not to have been man-made
because it was "too long".

It was also in this general vicinity that a Duke University expedition found conti-
nental rock, along the Aves Ridge.
