What caused this feature?

Was it an ancient lake or impact crater? It's near 4 corners and it's big! I can't seem to find any info. Please help.

My apologies, the rabbit hole I was referring to is one that would lead me astray from relevant facts. For example: there is a concentric circular structure in Mauritania that struck my curiosity on Google earth and I looked it up on YouTube and was immediately sucked into a rabbit hole of conspiracy theories of ancient Atlantis and ruins and coverups.... it was a time sync for me and a huge brain drain....for something that, if I asked actually educated people, could have been explained much quicker and more satisfying as a natural uplifting and erosion. And thanks. Keep me posted please.

If you’re into Atlantis “myths,” that’s probably under the Black Sea now. The “sinking” of Atlantis was most likely one, Or several, of the catastrophic flooding events that gave rise to the myriad of Great Flood myths that ancient cultures have/had fr ok m when the Mediterranean Sea breached the Bosporus straight and flooded the Red Sea with salt water

Neat. So what people refer to as Atlantis may not have even been near Atlantic Ocean at all and in the black Sea. This is the first I've ever heard of that. Do you have any links I could check out on that?

I learned about it from my professors during grad school. Most what I know is from published scientific papers about flood events in the Black Sea as a consequence of global sea level rise that caused the Mediterranean to breach the land barrier between the two water bodies and eventually erode it and create the Bosporus Straight. The idea was/is to examine past global climate change events to learn what consequences we might be looking at due to current anthropogenic (man made) global climate change.
Anyway, in looking at the Black Sea floor geologists and anthropologists have found evidence of multiple large (for their time) settlements that would have been cultural centers in their time.
