In the south/southwest, the circular formation is broken by a ravine, which continues into the formation as a wadi, providing entrance into the heart of the massif. The wadi starts after the confluence of four ravines, which divide the higher ground into five plateaus; at this confluence is a great circle of rock, surrounded by the overhanging plateaus. There is no source of water.[1] Erosion has washed away all loose material, leaving only spurs, and the gara presents itself as essentially a funnel with the constituent canyons leading toward a single exit.[3]
