Richat Structure

The Richat Structure, also known as the “Eye of the Sahara,” is a prominent circular feature in the Sahara Desert of west-central Mauritania. Measuring 30 miles (50 km) in diameter, the structure was originally thought to have been formed by the impact of an asteroid; however, it is now known to be an eroded structural dome of layered sedimentary rocks.
