What Lurks Under the Sahara?
It seems that the golden, majestic dunes of the Sahara Desert have always existed. But this is far from the truth. What secrets does the hot desert sand hide from humanity?
It’s hard to believe, but the arid desert, spanning 3.5 million square miles, was once covered with a thick, green carpet of vegetation, where entire settlements existed, domestic animals grazed and rainfall was abundant. Turn back the clock and you’ll find that dinosaurs roamed the Sahara and giant whales splashed through its seas.
Add to that the mystery of the Eye of the Sahara, a strange geologic formation comprised of huge concentric rings with a diameter of 31 miles. Located in today’s Mauritania, the structure baffles geologists to this day. Learn more about one of our planet’s treasures in this episode of Riddle.
