Erg Iguidi, Algeria

 

Erg Iguidi is one of several Sahara ergs, or ever-changing seas of sand, that stretch from Algeria to Mauritania. It is an area of sand dunes that can exceed 500m in width and height in a flat area of desert covered with little or no vegetation cover.

The pale yellow bands running through the image are ridges of wind-blown sand that form the Erg Iguidi. The center and upper right corner of the satellite image show a black sandstone rock. The light blue and white areas are limestone deposits and salt crusts left behind after evaporation of water in the area.
