Sand Surfing the Sahara

Photograph by Thomaz NapoleĆ£o

A sand surfer is dwarfed by colossal dunes in the Sahara near the Siwa Oasis in northwestern Egypt. The massive desert is traversed by endless rows of dunes called barchans ("crescent-shaped dunes" in Turkic). Barchans are found on the edge of sand seas and form when the wind blows steadily from one direction.
