Jordan’s North-Eastern desert, also called ‘The Black Desert’, is part of a huge volcanic field, the Harrat al-Sham. This volcanic field comprises a low but rugged basalt massif, which extends from Syria through Jordan into Saudi Arabia. It consists of a series of lava flows, numerous small cone-shaped volcanoes, extensional faults and large fissure eruptions.
The lava deposits weathered in the extreme temperatures of the desert (hot days and cold nights), cracking up and breaking apart into ever smaller rock masses, ultimately resulting in rocky plateaus covered with basalt boulders and extensive gravel plains. Travel in this area is difficult, and most archaeological sites can be reached only on foot. Summers are scorching hot, winters can be bitterly cold, and there are no permanent sources of water.
Jebel Qurma, Jibal Rijlat Suleiman, Wadi Rajil and Wadi al-Qattafi: the research region is barren and unforgiving, yet extremely beautiful. Moreover, the area is astonishingly rich in archaeological remains from many different periods.
