The Nubian Desert

The Nubian Desert is totally different from the nearby Bayuda one, even though they are separated only by the Nile valley. It is mainly sandy and it has a number of dune areas, sandy level grounds and isolated Nubian sandstone brown formations, often eroded in unusual shapes by the wind.
It is a very dry desert, where water is almost absent; as a consequence, there are no nomads tribes here. It is interesting to notice the presence of several places where there are petrified fossil trees; these are the remains of ancient forests which clearly prove that this desert was once covered by lush vegetation.
