Between 11,000 and 5,000 years ago, the Sahara Desert was a vast savannah teeming with lakes, rivers, and hippos. Cave paintings in the Tassili n'Ajjer mountains show swimmers, herds of cattle, and lush grasslands where today there is nothing but sand. Satellite radar has revealed the ghost channels of ancient rivers beneath the dunes, some as wide as the Nile. As the African Humid Period ended around 5,500 years ago, the green Sahara dried with startling speed — possibly within a few centuries — forcing its populations to migrate toward the Nile Valley, where the sudden concentration of displaced peoples may have catalyzed the rise of pharaonic Egypt. The question haunting researchers is what lies buried beneath those dunes: the settlements, monuments, and infrastructure of civilizations that thrived for millennia on land now entombed under hundreds of feet of sand.
