Tibesti Mountains
Ancient volcanoes pierce the Sahara's heart, leaving behind a landscape of craters, hot springs, and mineral-rich steam vents.
In Chad's remote north, the Tibesti Mountains rise dramatically from desert sand, their volcanic cores sculpted by millions of years of geological drama. Emi Koussi, the range's crowning peak, stands as the Sahara's highest point and marks where the continent's crust once churned with molten activity.
Five major volcanoes dominate Tibesti's central spine, each crowned by vast depressions that speak to explosive pasts. Lava flows blanket ancient sandstone, while fumaroles still exhale steam and mineral-laden gases—evidence that the earth's restlessness here never fully ceased.
Volcanic activity in Tibesti continued sporadically until the Holocene epoch, meaning some of these mountains were still erupting while humans were building civilizations elsewhere on Earth.
Test yourself
Which Saharan range contains the highest peak in the desert and still releases steam from active fumaroles?
The Tibesti Mountains in Chad feature Emi Koussi, the Sahara's highest point, and retain active fumaroles demonstrating ongoing geothermal activity from their volcanic geology.
