Answer:
Tibesti Mountains
Mount Koussi, or "Emi Koussi," is a large shield volcano located at the south-east end of the Tibesti Mountains. It is around 11,205 feet (3,415 m) high, and stands in the north of Chad, in the Borkou Region. There are no historical records of it erupting, and the volcano is somewhat presumed extinct; however, there is an active thermal area in the form of fumaroles, on the southern flank of the volcano.
The Tibesti Mountains run through northern Chad, to the south of neighbouring Libya, in the centre of the Sahara Desert. Bikku Bitti, the highest mountain of Libya, is also located within this range. The southern part of the Tibesti Mountains lie within the the watershed of Lake Chad, and five rivers course through the northern part of the range towards Libya. However, all rivers originating from this range do not run far, vanishing underground or evaporating in the intense desert heat. The Sahara covers a lot of northern Chad, covering around a third of the country's territory.
The Toubou tribe live in the Tibesti Mountains, and are known as some of the best camel racers in the world.
