Algeria - May 23rd, 2011

The Tassili n’Ajjer, a mountain range in the Sahara desert, is visible as a vast, dark brown plateau in the lower part of this image. It is located in south-east Algeria at the borders of Libya, Niger and Mali, covering an area of 72,000 sq. km.

Some large areas of orange sand dunes can be seen to the north; individual rows of dunes can be discerned in the full image.

Located within the light tan area situated between the plateau and the dune sea is the Tassili in Bider, an impact crater that sits in dry, rugged terrain in Algeria. Spanning 6 kilometres, the crater sits at the southern end of a range of hills. It has an elevated position and concentric rings.
