What is "sebaiera"

Sebaiera, Uad Sebaiera or Zbayra is a hamlet and wadi(Arabic for valley) in Western Sahara in Oued Ed-Dahab Province in the region of Dakhla-Oued Ed-Dahab on the Moroccan side of the wall in Western Sahara. There is an astronomical station there but it is very small and a few tiny shacks that seem to be permanently inhabited and nomads seasonally settle in Sebaiera. It is located in a wadi(valley) called Oued Zbayra and ephemeral river called Oued Zbayra. The structures in this hamlet are so tiny and utterly unassuming that they are not visible on Google Maps and the nomad's tents are only seasonal and also tiny so it is unlikely Google Maps ever shows them. It's elevation is 220 meters. It lies 104 kilometers east of Chalwa( Cnalwa) and is reachable only by jeep or dirt road.
