Mauritania-eye of Africa (Sahara Desert)





From space this mysterious depression in the Sahara Desert of Mauritania really does look like a human eye. The image to the left is the "pupil" but a visit to Google Earth zoomed out a little will reveal the cliffs that make up the rest of the eye. This natural phenomenon is actually a richat structure caused by the dome shaped symmetrical uplifting of underlying geology now made visible by millennia of erosion. Please note that this explanation is not wholly accepted by the scientific community. There still remain academics that believe it is the sight of a meteor impact and yet others still that believe it resembles the formations caused by underground nuclear blasts. By the way, we estimate that the detonation would have had to be in the gigaton range. Currently no country in the world has a weapon even close to this destructive yield.
This unique structure in the Sahara Desert of Mauritania can be seen from space. It is 50 miles wide and rather unusual for the fairly featureless Sahara. Though people often refer to it as an impact structure, it’s actually the natural result of hundreds of thousands of years of erosion. Formed from layers of sedimentary rock, fierce winds and shifting sand dunes have worn away at the material, leaving a crater impression behind. It is also known as the Eye of Africa.
Currently scientists believe that they know what caused this formation. Hey! It's a Ri chat structure ... whatever that really means. A more Bizarre theory is that it is the impact site of an ancient but very powerful bomb.
