Larger and more open than Wadi Mujib, the canyon of Wadi Hasa was the frontier between the lands of Moab and Edom to the south. Its gentler more exposed slopes are planted here and there with olives. Farmers access their terraces, small verdant pockets enlivening this rocky expanse, along hillside footpaths. Bedouin live in the valley bottom, their black tents and brown carpets visible on the right bank of the wadi. Their flocks of sheep and goats roam the lower slopes in quest of the odd clump of vegetation.
