Corridor Libya
The Great Sand Sea spans the desert between western Egypt and eastern Libya. Vast fields of dunes stretch southward from the vicinity of Siwa toward the Gilf Kebir plateau, covering a gently sloping surface of older rock. The long ridges of sand and the scarcity of water distinguish this part of the Sahara from the inhabited oases to the east. Wind has shaped the dunes into a landscape of immense scale.
