The Mysterious ‘Skull’ of the Sahara Desert
Hidden deep within the Sahara Desert lies a natural wonder that appears to be straight out of a horror movie – a spooky ‘skull’ carved by nature itself in a volcanic pit. When viewed from space, this eerie formation resembles a ghostly face staring back at us from the rocky terrain of our planet.

Although just an optical illusion, the sight of this skull-shaped formation is a fascinating spectacle. Human brains are wired to seek out faces in random patterns, a phenomenon known as ‘pareidolia’. And when the face we perceive is as sinister as this one, it adds an extra element of intrigue.
The ‘skull’ is actually formed by the Trou au Natron, an extinct volcano in Chad, locally referred to as Doon Orei, meaning “big hole”. This caldera, reaching depths of up to 1,000 meters, features a white facade created by a soda lake and natron deposits resulting from volcanic activity.

The ‘eyes’ and ‘nose’ of the skull are actually cinder cones, formed around volcanic vents. Situated in the Tibesti Mountains, the highest range in the Sahara, this remote region remains a mystery to scientists despite being studied since the 1960s.
Believed to have once contained a glacial lake around 14,000 years ago, the Trou au Natron now presents a haunting visage that peers into the depths of its abyss.
