Out of the flat immensity of southern Algeria rises the Hoggar — a great volcanic massif of black basalt spires, eroded calderas, and jagged plugs of ancient lava, straddling the Tropic of Cancer. The Tuareg call it Ahaggar, and to them it is home. To everyone else it is one of the most improbable landscapes on Earth: high enough to be cold, wet enough to be alive, a green-flecked island of biodiversity floating in the planet's greatest desert.

The massif is part of th...

Across the Hoggar and the neighbouring highlands, rock paintings dating back some six thousand years record a wetter, greener Sahara — herds of cattle, hunting scenes, the daily life of a world that has since turned to stone and s...

At In Ekker, in the massif's northern reaches, French engineers bored tunnels into the Taourirt Tan Afella, detonating a series of ...
