"During ice ages the water level dropped 400 and more feet below the current level. Also, the Mediterranean has dried up more than once. I once read their are 1,000 ft. thick salt deposits at the bottom of that sea. I believe we will find more such history if we look, because each ice age drove man back many steps from levels they had reached in good times." The Mediterranean has dried out completely over forty times. The last time was about five million years ago. There are miles (2) thick salt deposits on the bottom of the Med and the salt crystals are of a type that form only in direct sun light. There was an article posted recently about flooding in the Mediterranean. Maybe SunkenCiv can locate it for us.
