Issaouane Erg, Algeria - Photo is copyright Google (Google Earth).

The shapes and colors of the dunes in this desert are amazing. Notice that the three dunes have almost identical shapes. And there are tens of throusands just like those all around.

This area is a major oil field, dotted with oil pumping facilities and pipelines. You'll see them if you explore the surrounding with Google Earth.
