The Moving Dune

A vast sand mountain that has been advancing through the town for centuries

The most photographed thing in In Salah is its own slow-moving dune. A pale, almost luminous mound of sand pushed steadily eastward by the prevailing wind, it passes through the town at a rate of a few metres a year, burying whatever lies in its path. Houses on its windward side disappear under the sand; on the leeward side they re-emerge years later, scoured but intact.

The dune sits at the northern edge of town and is easy to find — any local can point you in the right direction. Climbing it gives an extraordinary view across the oasis and the Sahara beyond. Sunrise and sunset are the times to be on top.

A story
The dune has been advancing through In Salah for as long as the town has existed. Houses on the windward side eventually get buried; the residents move on, build again to the east, and let the dune pass. Old aerial photographs show the same dune in a different street ten years later. The settlement keeps shifting downwind, like a fleet sailing very slowly in the same direction as its enemy.
