The Sahara is a vast, inhospitable desert. However, even in this barren wilderness lie oases. Among these are Takedda, Tadmekka, Tessalit, Ghat, Gudamis, Gharama and Morzuq, Aoudaghost, Ouadane, Araouane, and Touat. All these oases were once used to get from the Mediterranean world to the then-unexplored lands of the River Niger. Some of these are still isolated from the outside world except by camel caravans. Araouane, for example, is still a village in the midst of the dunes of only a few puddles and forty-five scattered structures! How anyone managed to discover it is a mystery. Taoudenni as well is a mystery; it has only two small clumps of trees, a few scattered ruins and three square buildings. How did anyone discover the ruins of Aoudaghost, where only a few small rectangular structures can be seen growing along a sizable amount of vegetation?
And what of Tadmakka, where numerous buildings were built and an excavation recently took place?
And what of the crescent-shaped burial mounds in the western Sahara researched by Nick Brooks? What settlements are correlated with them? What is their chronology? What geological features are associated with them? Clearly, numerous opportunities for archaeological continue to exist in the Sahara.
