Gebel el Heda is a conspicuous hill situated ten kilometres north-north-west of Gebel Metawit, between the Wadis Antar and Khashab. Its highest point is 862 metres above sea-level.
Gebel Nukheira is a group of high hills on or near the main watershed, close to the head of Wadi Antar and about ten kilometres north-north-west of Gebel el Heda. Its highest point is 876 metres above the sea.
Gebel Ras Abu Etl is a lower hill seven kilometres north-east of Gebel Nukheira. As seen from the upper part of the Wadi Gemal it appeared to have a flat top, which is 648 metres above the sea. It is probably drained by the short Wadi Abu Etl, which joins Wadi Huluz to form the Wadi Gemal.
Gebel Um Suerab is a great high ridge of dark looking rocks, surrounded by high flanking hills, rising conspicuously in the hilly country between the Wadis Huluz and Gemal, about twenty-four kilometres north-north-west of Gebel Abu Hamamid. The top of its ridge, which appears to be nearly level for about a kilometre of its length, is 1,024 metres above sea-level. From its neighbourhood drain two wadis in opposite directions; one, called the Wadi Um Suerab lil Gemal, goes northward to join Wadi Gemal, while the other, called Wadi Um Suerab lil Huluz, is the longer and courses southward to join Wadi Huluz.
Gebel Durunkat is another apparently flat-topped hill eight kilometres south-east of Gebel Um Suerab, on the west side of the Wadi Durunkat, about thirteen kilometres above its junction with Wadi Gemal. Its summit is 924 metres above sea-level.
Gebel Abarun is a mountain range situated a short distance north-east of Gebel Abu Argub, from which it is separated by the Wadi Abarun. Its highest peak, almost due east of that of Abu Argub, from which it is separated by the Wadi Abarun, is 1,602 metres above sea, and overlooks the great plain of Selaia to the south.
Gebel Um el Tiur is a range extending south-east from Gebel Abarun, forming a southward prolongation of the mountains. Its highest peak is 1,450 metres above the sea, while the terminal peak southward is 1,080 metres. It is drained on the west by the Wadis el Shel and el Anbat (tributaries of Wadi Kharit) and on the east by the Wadi Um el Tiur (a tributary of Wadi Hilgit lil Kharit).
Gebel el Anbat is a group of lower dark coloured hills forming the south foot hills of Gebel Um el Tiur. Its highest point is 788 metres above sea, while a detached black hill a little west of it on the plain rises to 680 metres above sea, or 175 metres above the plain at its base. These hills are drained by the Wadi el Anbat and other small feeders of Wadi Kharit.
Gebel Um Usher and Um Hasidok are conspicuous peaks on the main watershed ten kilometres east, and twelve and a half kilometres east-south-east respectively of Gebel Abu Hamamid, rising to 1,487 and 1,497 metres above sea-level. They are drained to the south by the Wadi Hilgit lil Kharit, and to the north by the Wadi el Mahali, a feeder of Wadi Huluz.
Gebel el Mahali is a rather high peak of grey porphyry which forms a northerly extension of Gebel Um Usher, close south of the Wadi Huluz. Its top is 1,112 metres above sea, or 330 metres above the adjacent wadi floor.
