Some towns are located at the foot of the Tagant Plateau's slopes, which form cliffs in some places. Among these areas are Tichit, Moudjéria and Rachid. Tidjikdja lies on the Tagant itself. The Assaba Massif, where Late Ordovician glacial formations have been identified, is a southward prolongation of the Tagant plateau. The Aoukar, the dry basin of a former lake lies beyond of the southern escarpments of the Tagant Plateau.
