I fear that America will share the same fate when God lifts His hand from us.

Those look like Bigfoot tracks. ;8^)

Then in a catastrophe (called “bursting of the dam”) apparently of global dimensions, this country became a desert.

The theory goes that sometime after 16,000 BC when the Ice Cap began to melt, a huge slab slid off the Canadian Ice blocking the Gulf current and creating the Younger Dryas, thus changing the weather in the Atlantic.

When the ice blocking the current melted, the Atlantic weather changed again and rain no longer fell over the Sahara region as today.

The land was lower because the glaciers had trillions on trillions of cubic miles of water locked up. When the ice melted sea leval rose 400-700 hundred of feet worldwide. Weight had little to do with it.

I didn't think there was any question but that the desert once was awash. There are many fossil beds throughout the desert which point to major water-course events.
Maybe now they are getting to be able to map them more accurately.

The American awl bidness took FABULOUS photos some 80+ years ago in their quest for petroleum fields. They did the best available then.

Thirty years ago, the BEST was also done, all in the name of MORE awl.

Now, the imaging is better yet, still for the purpose of finding more "black gold."

Look up post-glacial rebound.

Must have been camel caused global warming.

Isn’t Petra in Jordan?

[Kenny Bunk]

Jordan, within whoseboundaries lies Petra, is a country invented in 1916. The HUGE Arabian Peninsula, which used to be called in the olden days a “Semi-Continent” contains Israel, Syria, Jordan, Iraq, Saudi Arabia, Yemen, Kuwait, Quatar, Oman, etc.

[Pelham]

I’ll defer to your eminent geographical scholarship.

‘Never argue with a Maineiac’ I always sez, especially one who fraternizes with ‘gators and G. Gordon hisself.

I was just wondering if there was another Petra that I wasn’t aware of.
