the granite mountains which form the above-mentioned chain on the watershed between the Red Sea and the lowland near the Ḥeǧâz railway. Naming them from the northwest, these mountains are al-Ḫejmri, al-ʻEnejme, Dafdaf, Ṣafwân, ar-Râwa, as-Sîḳ, aš-Šâṭi, and Ḳîr. From al-Muʻaffara they approach the sea like an arch, so that between them and the mountains of az-Zihed and al-Ṛâjme there lies a deep basin,

To the west there rises the elevated ridge of Dabbet aṣ-Ṣwêr.
