Gebels Nazla and Um Serg are moderately high hills lying to the south of Gebels Sufra and Abu Khrug, between the Wadis Shait and Natash.
Gorf el Natash is a syenite hill on the south side of Wadi Natash, about five kilometres south-west of Bir Masur, while Gebels Muktil (470 metres), Derera, and Um Goraf, are prominent hills lying still further south near Wadi Antar.

Gebel Ras Shait is a group of high rugged-looking reddish hills, probably of granite, at the head of Wadi Shait, near Gebels Nugrus and Migif. Its highest peak rises to 1,019 metres above sea. The west face drains directly into Shait, while the eastern and northern slopes drain into Wadi Gerf, which joins Shait far to the south-west. Between Gebels Migif and Ras Shait is a small range of hills dividing Wadi Shait from the head of Wadi Hafafit; across the south end of this range, which is composed of dark schists with white granite at its western foot, there runs a zigzag pass, fairly easy for camels, to the head of Wadi Nugrus.
Gebel Mudergeg is a high range of reddish hills, which with Gebels Ras Shait and Migif encloses the heads of Wadi Shait. Its highest point is 1,086 metres above sea. To the east of it are several other lower ranges, some of white and others of black aspect, which have not been approached closely.
Gebel Hangalia is a great mountain ridge running south-south-east for about twelve kilometres, from Gebel Ghuel to Gebel Zabara, consisting chiefly of schists. Its highest peak is 1,241 metres above sea-level. Its western faces are drained partly to the Nile by the Wadi Hangalia (a tributary of Wadi Gerf) and partly to the sea by the Wadai el Nom (a tributary of Wadi Nugrus); its eastern faces, which are flanked by high ridges, drain into the various feeders of Wadi Ghadir.
