The Richat Structure: The 'Eye' of Earth

Questions arise over the creation and meaning of this strange and beautiful structure located in the midst of a rather barren desert. Could it be some strange creation of a former civilization, or is it a natural formation?



The Richat Structure is a huge crater-like fomation in the Sahara desert. This feature has generated interest for years since it has such an unusual appearance and the way it has formed has been something of a mystery in a mostly desolate area. The structure has a diameter of approx 50 kilometres (31 mi)



"Spectacular formation remains a puzzle:

Looked upon from space. Originally thought to be a crater, this volcanic dome is most likely a product of erosion, an ancient geological artifact in the middle of featureless Maur Adrar desert, in Africa's Western Sahara. The earliest space missions used it as a landmark, the adventurous 4x4 enthusiasts consider it to be their playground, and scientists are still debating its origin..."
