Mountain ranges change over time. The middle east was much wetter in historical time frames than today, as was New Mexico.

A “Wet Sahara” makes me ask “How long till it is wet again?”

Now, what happened to the lake? Did the Dinosaurs drove their SUVs and caused it to be boiled off? No, it was caused by the sun’s activities...

I blame it mostly on Jerry Brown’s water management policies.

There are YUGE aquifers deep under the desert.

They mine SALT by hand in the desert. They saw off big chunks and load them on camels to take them to market.

Where did the salt come from?

IMO, Planet Earth was knocked akilter by a passing celestial body (earth-crust displacement). The Flem-Ath book says 17% (IIRC), causing the ice age to end and perhaps sloshing the oceans out of their beds. Those living on the pivot points survived, but it was Katie Bar The door for the outliers.

Egyptian priests told the Greeks that the sun had, on two different occasions, risen in the West. If true, Mother Earth has had her butt whipped on many occasions.
