Toussidé (also known as Tarso Toussidé) is a potentially active volcano and the westernmost volcano of the Tibesti Mountains. The peak rises 3,265 m (10,712 ft) above sea level, and the volcano’s base measures approximately 55 miles (90 km) in diameter.

The peak is almost centered within the black shape that has tentacle-shaped lava flows extending down the western flank. The light brownish area surrounding the peak shows a distinctive radial drainage pattern that is quite common for stratovolcanoes as the terrain falls away from the main peak.

The depression southeast of the volcano measures approximately 5 miles (8 km) in diameter and 3300 feet (1000 m) in depth. Its white color is caused by an accumulation of carbonate salts, creating this soda lake of Tibesti.

With the exception of small vents that emit gasses and a few hot springs that continue to deposit minerals at the surface of the crater floor, little volcanic activity presently occurs in this region.
