Star Dunes, Algeria

 (JPG) Star Dunes, Algeria (1,490,962 bytes) ( 2,523 x 2,922 )
Radially symmetrical, star dunes are pyramidal sand mounds with slipfaces on three or more arms that radiate from the high center of the mound. They tend to accumulate in areas with multidirectional wind regimes. Star dunes grow upward rather than laterally. They dominate the Grand Erg Oriental of the Algerian Sahara, as depicted in this image acquired October 27, 2012. It covers an area of 37 x 43 km, and is located at 29.8 degrees north latitude, 7.9 degrees east longitude.
