Wadi Rum Tours
Coming from the northern plateau, the first sight of Wadi Rum is a bird’s eye vision of crags and pinnacles thrusting up from the sandy desert floor, each stacked behind another till they dissolve in haze. This vast tract of southern Jordan takes its name from the grandest of a whole network of wadis.
‘They were not unbroken walls of rock,’wrote T. E. Lawrence, in one of several lyrical passages on Wadi Rum in Seven Pillars of Wisdom, ‘but were built sectionally, in crags like gigantic buildings along the two sides of their street… They gave the finishing semblance of Byzantine architecture to this irresistible place: this processional way greater than imagination… Landscapes in childhood’s dream were so vast and silent’. Lawrence came here during the Arab Revolt of 1917-18, when tribal politics or logistics required it, or to find solace. Much of David Lean’s 1960s epic, Lawrence of Arabia, was filmed here.
Because of its springs, the area has been inhabited at least since Neolithic times. For millennia it was used by nomadic tribes, and by traders en route to or from southern Arabia; many left drawings on rock faces, or graffiti in Thamudic or Nabaraean script (in which they called the area ‘Iram’). A temple dedicated to the goddess Allat, built earlier by the tribe of ‘Ad, was restored in the ttme of the Nabataean Ktng Aretas IV; and the settlement near it dates to Rabbel II’s time.
The geology of Rum
The formations of Wadi Rum are a spin-off from the series of cataclysms that created the Great Rift Valley, of which the Jordan rift is the deepest part. The layers of rock thrown up here were rearranged in the criss-crossing fault lines that we see today. Most run NNE-SSW but they are traversed by counter-faults in every other direction.
The valley floors lie c. 900-I,000m above sea level, and the sandstone crags rise a further 500-750m. Jabal Ram (I,754m), the highest peak in the region. is the second highest in Jordan; but Jabal Umm Jshreen, facing it across the wadi, is only one metre lower. Mostly hidden beneath the surface lies a base of pre-Cambrian granite at least 2,000 million years old. Above it are sandstones of varying ages and colours – first red Cambrian (600 million years old), with grey Ordovician above it, then pale beige Silurian – each about 100 million years younger than the one below. Rain and wind have sculpted the sandstones into forms that resemble domes, organ-pipes or dripping candle wax, and have created rock arches over canyons.
All the strata tilt down eastwards and in western areas the granite base is visible above the wadi floor. Particularly on the east face of Jabal Ram, springs occur at the interface between granite and sandstone, caused by winter rain penetrating the porous sandstone, stopping on the impermeable granite and trickling east to form pools with lush foliage.
