The Eye of the Sahara, also mentioned
because the Richat Structure could also be a 28-mile-wide site of a giant
concentric circles found within the western African country of Mauritania.
Geologists initially thought the situation was created by an asteroid impact,
but there isn’t enough melted rock among the rings to support this theory.
Similarly, there’s no evidence to suggest an eruption. New Age enthusiasts hint
that the eye of the Sahara could represent the remains of the mythical sunken the island of Atlantis supported Plato’s allegory.
More recently, geologists have proposed
that the eye of the Sahara could be an eroded, collapsed geological dome,
formed some 100 million years ago when the supercontinent Pangea broke up.
Bolstering this theory are ancient rocks found on the surface, which originated
the utmost amount as 125 miles beneath the Earth’s crust and before life
existed on Earth. Research continues.
