A recent study has confirmed that a huge flood occurred about 7000 years ago in the Black Sea. The 
theory was first put forward last year by marine geologists William Ryan and Walter Pitman. In their 
book Noah's Flood, they claim that the great flood resulted from the last ice age, which peaked 
12,000 years ago. When the poles froze, ocean levels dropped and cut off the Mediterranean from the 
Black Sea which dropped 150 m. to become a lake with fertile shores. When the ice melted, the 
Mediterranean rose back up and broke through what is known as the Bosphorus with a force equal to 
200 Niagara Falls for a period of two years. The Black Sea rose, consuming a mile of shore a day. 
Those who had settled there sailed away, spreading their stories of the flood.
