=Gebel Um Maiat=, a long high ridge stretching south-east from Gebel Eidab, has three marked summits near its ends and centre; that at the north end, which is the highest, is 928 metres, while the other two are 870 and 842 metres above sea respectively. Another broken ridge, of similar height, for which I could get no name from my guides, forms a south-eastern prolongation of Um Maiat, and extends to the Wadi Kalalat; this likewise has three well defined summits, rising in order from north to south, to 875, 821, and 627 metres respectively. These ridges are drained to the east by the Wadis Murra (tributary of Abu Daba) and Mindeit. Their western drainage has not been studied in detail, but it all reaches the sea, none of it going Nilewards; part of the drainage is probably taken by each of the Wadis Kalalat, Shut, and El Khiua. To the east and north-east of the Um Gunud — Eidab — Um Maiat range is a great expanse of lower hill country through which the wadis cut their way eastwards for about fifteen kilometres to the coast plain. The most conspicuous peaks in this lower hill country are Gebels Um Huk, Abu Ghalqa, and Um Hegilig, all situated in its north portion round about Wadis Lahami and Naait. Other low rugged hills fill a triangular tract south-west of the main range. =Gebel Um Huk= is a sharp granite peak, surmounted by a cairn,[109] rising to 517 metres above sea-level near the south side of Wadi Lahami, fourteen kilometres north-north-east of Gebel Um Gunud. =Gebel Abu Ghalqa= is another high granite hill, also marked by a cairn on its summit, seven kilometres south-south-east of Um Huk. The cairn is 561 metres above sea-level, and is in latitude 24° 1′ 7″, longitude 35° 16′ 47″. =Gebel Um Hegilig= in a small rather spiky range of red granite hills situated a little to the north-east of Gebel Um Gunud, near the heads of Wadi Naait. To the north-west of Berenice are several low hills on the coast plain, which serve as landmarks and bear special names. =Grain el Rih= is a conspicuous isolated low hill nearly opposite the place where Wadi Naait emerges from the hills on to the plain, thirteen and a half kilometres north-west of Berenice. =Khasheib Abu Daba= is the name of some low bouldery granite hills at the place where Wadi Abu Daba enters the plain. =Sikeit=, a landmark for Berenice, from which it lies five kilometres north-west, is a low granite hill, isolated on the plain and very conspicuous; its summit is seventy metres above sea-level, or thirty-eight metres above the plain at its foot.
