STRANGE PLACES - Eye of the Sahara ...

The Richat Structure is also known as the Eye of the Sahara. It’s a distinct and prominent circular geographical feature in the Sahara Desert. At roughly 30 miles wide, you probably wouldn’t notice that you were within it, but from an aerial view – and even from space – it is highly visible. Originally, it was thought to be the product of an asteroid impact and later people thought it could have been created by a volcanic eruption.

Il nostro Pianeta ha poco da invidiare ai paesaggi lunari o alle distese  rosse di Marte. E non solo per la varietà dei panorami, visto che  alcuni scorci sembrano visioni extraterrestri. Le strutture di Richat,  in Mauritania - note anche come ''l'occhio del Sahara'' - sono solo un esempio:
