Richat Structure (Eye of the Sahara)

GeoglyphAfrica

Concentric ring structure ~50 km across in the Adrar Plateau of Mauritania, visible from space as a perfect series of geological rings. Conventional reading : a deeply eroded geological dome formed over hundreds of millions of years by differential erosion. Independent reading (Bright Insight, Jimmy Bright, Archaic Lens) : the dimensions, concentric geometry, surrounding salt deposits, and freshwater channels match Plato's description of Atlantis with striking specificity. Archaic Lens has documented multiple ground-level expeditions showing what may be anthropogenic features within the rings, including aligned stones, possible megalithic terraces, and evidence the central depression was once a lake. The Atlantis hypothesis remains heterodox; the geological scale and visual drama of the site are not in question.

Look Closer — this site carries open questions: stones heavier than the period's tools could lift; geometry beyond period explanation; dating rests on thin stratigraphic evidence.
