Lake Urmia is a large but variable salt-water lake just inside the Iranian border from Turkey. Those of you who have read Early Genesis, the Revealed Cosmology know that I argue that the flood of Noah was local in extent. It still would have been global in effect because it would have eliminated the line of Messiah who would redeem the world. I also argued that it was an eastern highland flood, not something that happened in primarily in what would be Babylon or Sumer. Taking the genealogies from a calendar-patriarch perspective puts the flood at 4,500 B.C., or just over 6,500 years ago.
The only problem was that I had no evidence of an eastern highland flood. I was just going by how I read the text of scripture, not evidence from the natural world. So I started looking. I figured a key area would be Lake Urmia, and its mentioned several times in my book as a reference point in the flood. An Aras River valley flood would wash out there.
That led me to this paper (click on the "full text PDF" button on the upper right). On page 15 (study page 658) just above conclusions it notes: "The Holocene record is unavailable
due to the loss of the upper 4.5 m of sediment." What? How did 4.5 meters of sediment get washed away right around the time I was interested in?
Look at the chart on page 13 (study page 656) closely. They took core samples corresponding to 200,000 years. Only once before in all that time was a layer of sediment lost from Lake Urmia. That was around 100,000 years ago and it was only about 1/10th the sediment lost in the Holocene. What happened in the last 10,000 years that took 10 times as much sediment as was taken in the last 200,000 years?
