Site E-75-9: The Excavation of an El Adam (?) Early Neolithic Settlement at Nabta Playa
A large phytogenic dune, probably of Final Pleistocene age, occupies the floor of the Nabta basin along its eastern side. During the early Holocene this dune formed the shore of the seasonal lake that filled the lower part of the basin. At that time the dune stood much higher than the lake and it was a favored place for camps throughout the Early Neolithic. In some areas it is still higher, even today, than the nearby playa surface, because the artifact scatters from the camps are so dense that it armors the surface and retards deflation. Elsewhere, particularly at its southern end, where there are not as many sites and the occupational debris is not so dense, the soft dune has been eroded by the wind, leaving deflational hollows. It is a classic topographic inversion, with the more cemented and thus higher playa sediments adjoining a slightly lower dune hollow.
