Poste Maurice Cortier (Bidon 5)

Tanezrouft, located west of the Ahaggar massif, is the one of the most arid regions in the Sahara. In that place, there are the remainings of an abandoned french gas station for airplanes that travelled to the south. This place is
called Poste Maurice Cortier, but also known as Bidon 5 because it was signaled with a number 5 upon a bidon, for this was the fifth beacon in the road between Reggane and Tessalit. It feels strange that this place is still marked as a village in the maps; in some simple maps found in books it even is signaled with the same circle as Tamanrasset, a town with several dozens of thousands of inhabitants.

Well, if you are lost in the desert in urgent need of water, and you see this "town" in your map, I think you shouldn't go there for getting water...

PD: In the year 1809 were found the corpses of 2000 caravaneers and 1800 camels in the Tanezrouft. To get lost in a desert that lacks landmarks is a real danger for the caravans.
