=Gebel Egat=, one of the best known and most remarkable of the mountains of the group, is a high steep cone rising to 1,145 metres above sea on the north side of the Wadi Alaqi in latitude 22° 5′ 39″, longitude 34° 52′ 15″. It is a landmark for Bir Egat, which lies about five kilometres to the east, and for the mines of Alfawi, which lie some ten kilometres south-east of the peak. =Gebel Shanaiyet= (907 metres) and =Gebel Hamida= lie south of the Wadi Defeit, between that wadi and the Wadi Egat. =Gebel Hateib= or =Suhin= (854 metres) forms the main collecting ground for the Wadis Hateib and Suhin, which are tributaries of Alaqi. =Gebel Um el Tiur el Foqani= is a group of very high steep hills on the south side of Wadi Defeit. It has a well-marked peak as its summit, in latitude 22° 17′ 56″, longitude 34° 41′ 14″, 946 metres above sea-level. This peak forms a point on the administrative boundary between Egypt and the Sudan. =Gebel Um el Tiur el Tahtani=, situated some twelve kilometres west-north-west of the foregoing, and on the opposite side of the Wadi Defeit, is a somewhat similar but lower group of hills, its highest point rising to 783 metres above sea. =Gebel el Adraq= (770 metres) and =Gebel Guqub= are two other hill-groups south of Gebel Um el Tiur el Tahtani, lying between the Wadis Defeit and Alaqi. Gebel el Adraq is a landmark for some old mines called Betan, while Gebel Guqub is the collecting ground, the drainage of which supplies the important well of Bir Guqub. =Gebel Muqsim= is a conspicuous mountain on the south side of the Wadi Alaqi near the meridian of 34°. The triangulation cairn on its summit is in latitude 22° 10′ 11″, longitude 34° 1′ 12″, at an altitude of 825 metres above sea-level. Gebel Muqsim forms a point on the administrative boundary between Egypt and the Sudan. =The Elba-Shendib Group.=
