Idhan Murzuq or Edhan Murzuq (with the second name also written as Murzuk) is one of the most beautiful desert sites in the world. Massive and complex sand dune formations, best appreciated from above, as shown in the following photograph.

The above NASA's astronaut photo of Edhan Murzuq, from
(http://earthobservatory.nasa.gov/IOTD/view.php?id=36675), was taken from low earth orbit. The photo beautifully illustrates the classic large and small sand masses of the central Sahara. The above sand masses (locally known as Draa) are shaped by wind separated by smooth-floored, almost sand-free basins. Geologists distinguish three types of sand dunes: longitudinal dunes; transverse dunes (curved); and star dunes (with several arms converging towards a single peak).
