Hammada du Guir
The Hammada du Guir is a hammada , a rock and stone desert, and is located as a rocky plateau in the Sahara - Bechar province of south-western Algeria , named after the Oued Guir , which flows south from Morocco to the east.
The Hammada du Guir extends from south to north over a length of around 260 km from the area at the Oued Saoura near Béni Abbès opposite the dune areas of the western Great Erg to just over the border with Morocco. The east-west extension reaches 100 km in places. In the south, the dune areas of Erg Er Raoui and the mountainous area of the Ougarta Mountains connect .
The height of the Hammada rises from around 500 m on the Oued Saoura in the south to 750 m in the center and 1150 m on the northern edge, before the terrain breaks off into the Boudnib valley in southern Morocco.
The oasis town and commune of Abadla on the Oued Guir is of central importance for traffic through the Hammada du Guir . From here the national road 6 leads along the eastern edge of the Hammada to the south, and the national road 50 leads through the center of the Hammada Guir to Tindouf in the westernmost province of Algeria. In the middle of the otherwise hostile and deserted desert, Hammaguir was built near the N50 in French times as a rocket launch site for the French Center interarmées d'essais d'engins spéciaux .
