Plus all the details that conveniently line up. The mountains with rivers to the north. Being south of the Atlas mountains – Atlas being the first king of Atlantis. "Atlantis" meaning "island of Atlantis" is interesting because it's likely that if water were present in the rings, it would have the appearance of an island, and there are two forms of evidence that there was: zoom out on Maps/Earth and see the obvious water blast the sand experienced coming from the Atlantic; there is also salt present in the rings.

Is it Atlantis? Maybe not, but there a number of stiking coincidences.
