The Northern Ḥeǧâz
(1926)
“ We turned back northward through the defile of ʻElw al-Jitâma, as I wanted to journey through Wâdi al-Jitm to the settlement of al-ʻAḳaba. Before us, to the northwest, rose the dark mountains of Sarbûṭ al-Amṛar with their vertical ribs, on which stand steep-walled, red, natural strongholds. The vertical ribs are of granite and the strongholds of limestone and sandstone. ”
