Stars of the Ursa Major and Ursa Minor (with Polaris near the rock) stand above moonlit sand dunes and eroded sandstone cliffs in the remote Tassili National Park in the southern Algeria near Niger border.

In addition to dramatic sandstone formations, the Tassili region is noted for rock paintings and archaeological sites dating to neolithic times.
