The Eye of the Sahara

One look at the Richat Structure, a 30-mile-wide geological oddity transports your imagination straight into a sci-fi movie.

But you don’t need to travel to some far-off galaxy to see this natural wonder. Just head deep into the Sahara desert until you reach the Ouadane in Mauritania.

Scientists believe it was created by a magma eruption that caused the desert floor to swell and the layers of rock were pushed up and fractured.

Over thousands of years, the high winds and sands gradually leveled them flat, forming the structure’s unique concentric rings.
