Tibesti Mountains
21°N, 17°E — Central Sahara, northern Chad — shield-volcano range with hot springs
What's documented
The Tibesti Mountains are a range of shield volcanoes in the central Sahara, in northern Chad. The highest peak, Emi Koussi, rises to 3,415 meters and is the highest point in the Sahara. The range contains active hot springs (with water temperatures around 37°C), lava fields, and extensive rock art predating the Toubou people who currently inhabit the region. The Tibesti rock-art record spans roughly 10,000 years; iconographies shift over time in ways the academic Saharan-prehistory literature continues to debate.
