Richat Structure: The Eye of Africa

Richat Structure (or The Eye of Africa) is one of the coolest geologic formations in the world and is located in the Sahara desert near Ouadane, west–central Mauritania. Richat Structure in Mauritania also known as the Eye of the Sahara has a diameter of 50 kilometers. The feature is so big that NASA has used Richat Structure as a global landmark.

The origin of this perfectly circular shaped body has been heavily debated by geologists. Hypothesizes as meteor impacts and volcano hot plumes have been widely discussed. However, today most scientists agree on the structure is a deeply eroded geologic dome forced by circular anticline folding which occurred for over 100 millions years ago.
