“The shadows of rocks both tumbled and towering dip into valleys on the floor of the Sahara. Here on a plateau in the Tassili n’Ajjer region of Algeria, the desert and its rock forests shelter prehistoric remnants dating to 10,000 B.C. Ceramic materials, paintings, and 15,000 engravings—among other artifacts—have been identified since the first discoveries at Tassili in 1933.”- (Via National Geographic)
