The Eye of the Sahara

The Eye of the Sahara, also known as the Richat Structure, is a massive circular formation in Mauritania's desert, spanning about 50 kilometers. It appears as a series of concentric rings and is visible from space. Geologists believe it formed through volcanic activity followed by erosion that removed softer rock layers, revealing the resistant rock structures. Its striking shape has made it a notable landmark and an intriguing natural feature, often mistaken for an impact crater, though no evidence supports this. The structure offers valuable insights into Earth's geological history and processes shaping the landscape.
