I'm a bit slow on this news item due to the fact that when first reported some took it as a hoax and then I forgot about it,,,I find it quite fascinating that it has taken this long for the "evidence" to be found as this theory was one proposed back in 1997,,,never one to believe in the global flood theory I found the Ryan/Pittman theory palatable and supported in a sense by the numerous flood myths,,,
Columbia University researchers William Ryan and Walter Pittman speculated in their 1997 book “Noah’s Flood” that when the European glaciers melted, about 7,000 years ago, the Mediterranean Sea overflowed into what was then a smaller freshwater lake to create the Black Sea.
It will be interesting to see where Ballards work drives this theory,,,
“So we know that there was a sudden and dramatic change from a freshwater lake to a saltwater sea 7,000 years ago,” he said Tuesday.

“And we know that as a result of that flood a vast amount of land went under water.

“And we now know that that land was inhabited. What we don’t know is who these people are, we don’t know how broad their settlements were ... but we’re expanding our studies to try to determine that.”

Ballard said his team, using remote-controlled underwater vessels with cameras, located a former river valley beneath the sea, and in the valley was the collapsed structure. Remains include preserved wooden beams that were worked by hand.
