What's hidden under Sahara desert

What's hidden under Sahara desert? When we think of the Sahara Desert, we imagine the vast amount of golden sand, sand dunes and maybe the odd camel or two. But there is more to this desert than meets the eye. Blanketing much of the northern third of the African Continent, or some 3.5 million square miles, the Sahara Desert, which is the largest desert in the world, extends eastward from the Atlantic Ocean some 3,000 miles to the Nile River and the Red Sea, and southward from the Atlas Mountains of Morocco and the Mediterranean shores more than 1,000 miles to the savannah called Sahel. More than 16 times the size of France, the Sahara Desert blankets nearly all of Mauritania, Western Sahara, Algeria, Libya, Egypt and Niger, the southern half of Tunisia, and the northern parts of Mali, Chad and Sudan. In this video we are going to take a look at what is hidden underneath all that sand, and find out how the sand got to be there.
Deep in the Sahara desert, ancient rock paintings depict a verdant world full of elephants, cattle, giraffes, hippos, and antelope. The people who created these images lived in North Africa when the now hyperarid Sahara was a very different place. While today the Sahara is a dry, sandy, mostly inhospitable place, new evidence is showing us how a lush and verdant ecosystem may have been maintained, as researchers have discovered the remains of a prehistoric river system buried beneath the desert and lost to the sands of time.
