It Was Once An Oasis Around 11,000 years ago, the northern strip of Africa that is now occupied by the Sahara Desert received lots of rain and was full of vegetation and water, including forests, lakes, grasslands, and an extensive network of rivers. 7. Mysterious Stone Structures Archaeologists recently spent several years studying hundreds of stone objects found in the Western Sahara territory. These stones are estimated to be thousands of years old and people used to make little figures and structures out of them. 6. The Eye of the Sahara The “Eye of the Sahara,” also known as the Richat structure, is a 25-mile-long geologic formation that looks like a bull’s eye and can only be noticed from a bird’s eye view. It’s located in Mauritania in the western Sahara Desert. 5. Cosmic Glass Earlier this year, scientists published a study about the origins of Libyan desert glass, a naturally-occurring, canary yellow material that has been prized for its beauty for over 3,000 years. Libyan desert glass is made of the purest silica ever found on Earth. It formed around 29 million years ago as the result of some type of event involving temperatures above 2,192 degrees Fahrenheit (1,600 degrees Celsius). 4. An Ancient Megalake As technology continuously improves, researchers are learning more about the ancient structures and formations that lie beneath the Earth’s surface. In 2010, scientists discovered evidence of a prehistoric megalake in the eastern Sahara. It was formed around 250,000 years ago when the Nile River pushed through a low channel and flooded the region. 3. Thriving Civilizations In 2011, satellite images revealed the ruins of a long lost civilization that existed before and during the Roman era in the Sahara Desert. In areas where there appears to be nothing but desert, the images show that extensive development once existed. The “Garamantes” civilization that occupied the region around 1,000 BC was highly advanced, despite Roman descriptions of them as uncouth and barbaric. 2. IT’S EXPANDING With an area of 3.6 million square miles (9.4 million sq. km), the Sahara Desert is roughly the size of the United States, and it’s getting bigger. Over the past century, it’s grown by about ten percent, and scientists believe this may be partially due to climate change. The deserts are growing and the forests are shrinking. 1. The Lake of Gafsa In July 2014, a shepherd in discovered a lake in the desert about 15-and-a-half miles (25 km) from the Tunisian town of Gafsa - where there shouldn’t be a lake. The 2.6 acre body of water measured 59 feet (18 meters) deep and was named Lac de Gafsa.
