The Tanezrouft (Arabic: تنزروفت) is a natural region located along the borders of Algeria and Mali, west of the Hoggar Mountains.

This area has no permanent residents and is known for its soaring temperatures and scarce access to crucial resources: water and food.

[2] The terrain shows stark evidence of long-ago water erosion when the Sahara Desert's climate was much wetter, but the present annual rainfall is much less than 20 mm.

Today the terrain is being shaped by wind erosion, which occurs much faster than in other areas, since there is little or no vegetation to hold the surface in place.

Since perhaps 500 BC[4] a desolate trade route has connected the Niger River with the Tidikelt, Touat and the Hoggar in Algeria.
