Maybe he was trying to dig down, uh, forget it...

I think the first suspicion was raised during the prelim to the construction of the Aswan High Dam. Checking for the depth of the bedrock, the engineers found that the Nile runs atop a filled-in gorge, not unlike many a river gorge in our own southwest. When the Mediterranean was mostly dry land, the Nile flowed into it at quite a bit lower elevation. After the Atlantic surged in, the seawater backed up into the gorge for many miles, probably helped fill it in, and the rest was contributed by the silt-bearing Nile flood. :')

Yup. But there was a problem. The bottom layers of the silt contained salt water shells which indicated that salt water was 'upstream' as far as the Aswan dam. This data is used by one scientist (forgot who) to support his theory that the Ice Age melt water at one time (briefly) exceeded todays levels.

Also, I've read one description of the Nile Valley that compared it to the Grand Canyon during the Ice Age.

Riddle me this Therea did the same thing in 1600 BC, the 6.5 Cu Km Stuff, and the suffering was minimal, we need a bigger bang than that.

We had a real Big bang around 1150 BC, Where(?), that destroyed Mediterranean Civilization, Blam has better ideas on that than I.

It would seem to me that if Etna went South, the coast line would limit the damage further east.
