Saharan Star Dunes Satellite Image Silk Tie

Saharan Star Dunes Satellite Image Silk Tie

Satellite image of star dunes in the Grand Erg Oriental, which is a 75,000 square mile (about 20 million hectare) "sand sea" in the Sahara desert in Algeria. The colors have been changed for artistic purposes. Tie is silk.

The winds in this part of the Sahara blow from all directions, rather than blowing consistently from one direction, so the sand dunes don't have one dominant orientation, and are often star-shaped.

Price $19.
