Richat Structure, Mauritania- This prominent circular feature in the Sahara desert of Mauritania has attracted attention since the earliest space missions because it forms a conspicuous bull’s-eye in the otherwise rather featureless expanse of the desert. Described by some as looking like an outsized fossil in the desert, the structure, which has a diameter of almost 30 miles, has become a landmark for shuttle crews. Initially interpreted as a meteorite impact structure because of its high degree of circularity, it is now thought to be merely a symmetrical uplift that has been laid bare by erosion. Paleozoic quartzites form the resistant beds outlining the structure.

Impact crater?

Natural anomaly?

Ancient strip-mining site?

I'm probably wrong here , but to me it looks like a pit mine.

I don;t know what this structure is but there has been a few reported wierd structures, one was located by google earth in the Algerian Sahara desert, www.youtube.com... and also in Mount Tassili in the Sahara are some of the first known cave paintings depicting astronaut type figures from over 30,000 years ago. Intriguing area.

If it's endogenic it could have something to do with the heat of the earth reacting with substance on the surface.

Its part of Africa and to me always looked like Atlantis. Its called Mauritania or something to that effect. when the continents were closer together it might have resided about where the Cherokees said it was.

If the capitol of Atlantis had a ringed structure as they say, though I am sure there is speculation, we really don't know how that structure would have been formed.


circular cuestas represented by three nested rings dipping outward

Atlantis had three rings of land surrounding the central peninsular port and capital of Atalan. A singular distinction. These three almost concentric rings....

I don't have any idea what it is, but it's oddly beautiful.

Check out this site, some amazing pics of man made holes in the Earth, even the largest, but they are dwarfed by the Sahara site.

They look similar though.

If anything was going to make me believe Atlantis was something other than a story created by Plato, this would be it.

It's amazing the beauty that can be found on earth.

Cool looking place, reminds me of this one in russia which is all natural, even though it dosn't look like it.

Can't remember the name of the place, so couldn't find some info on it.
But i would guess Phage know something

That's interesting, although it does say an abundance of Quartzite, maybe it was a volcano that didn't quite make it...like a flat Yorkshire pud!

The Sahara used to be covered in water at some point.

I would assume water erosion would come into play.

But we always tend to pick one thing is has to be........y ?

It would be water erosion , plus the natural uplift, plus something else.

keep an open mind ... but not too open.

It's not this, it's not that, then it must be this.
System of elimination doesn't always work.
It's circular, they didn't explain that.
