Lava Flow by Toussidé Volcano in Tibesti Mountains, Libya and Chad

Creating a brown contrast against the yellow sands of the Sahara Desert are the Tibesti Mountains, a range of inactive volcanoes located on the northern edge of the Chad Basin in the Borkou- and Tibesti Region of northern Chad. The northern slopes extend into southern Libya. The massif is one of the most prominent features of the Central Sahara desert and covers an area of approximately 100,000 km2 (39,000 sq mi). The dark brown area visible within the mountain range is a lava flow around the Toussidé Volcano.
