Gebel Shiab is a collection of peaks rising from a rugged country of lower hills about twenty-eight kilometres east of Gebel Is. Its highest point is 987 metres above sea-level. Gebel Shiab appears to form the main head of Wadi el Qurat, an important feeder of Wadi Di-ib.
Eqrun (the horns) is a conspicuous group of schist hills lying between the Wadis Meisah and Ibib. It has two principal peaks; the higher one, surmounted by a triangulation beacon, has the position latitude 22° 30′ 10″, longitude 35° 37′ 9″, and is 473 metres above sea-level; the other is about 400 metres south-east of the beacon, and is only five metres lower. Eqrun itself is an isolated hill group, but close to the north-east of it there is another hill-mass of greater extent and of but little inferior height.
The country south of Eqrun forms an extensive tract of low hills with much blown sand. Two conspicuous hills in this tract rise above the rest and bear special names; these are Tahaqayet (432 metres) and Titailibab (593 metres).
Kolmanab and Einiwai are two small but very conspicuous black hills eleven kilometres apart, rising from the sandy coast-plain between the Wadis Meisah and Di-ib. Both are surmounted by triangulation beacons, that on Kolmanab being in latitude 22° 32′ 26″, longitude 35° 53′ 36″, 137 metres above sea, and that on Einiwai being in latitude 22° 27′ 50″, longitude 35° 57′ 59″, 138 metres above sea. North-west of Kolmanab are some low banks called Tinadei, while about mid-way between Kolmanab and Einiwai is an isolated low hill called Ankalidot.
Osnei is a small but conspicuous red granite hill, rising to 251 metres above sea, thirteen kilometres west-south-west from Einiwai. It contains a galt, which yields water for some little time after rain has fallen locally.
Ti Keferiai is a conspicuous little isolated group of dark hills of no very great height, situated in the fork where the Wadis Didaut and Baueiwai join to form the Wad el Qireira. There are heavy accumulations of blown sand round the north-east flanks of the mass. The triangulation beacon on the summit has the position latitude 22° 21′ 0″, longitude 35° 49′ 47″, and is 494 metres above sea-level. Ti Keferiai forms a good landmark for the old mines of Romit, which are situated in some lower hills five kilometres south-west of the beacon. There are numerous excavations here in veins of smoky quartz with calcite and chalybite, which penetrate the country rock of highly crushed and decomposed diorite; a number of ancient grinding mills of diorite lie scattered about the place.
Four kilometres north of Ti Keferiai, on the opposite side of Wadi Didaut, is a conspicuous hill of very red granite called Adatalob Adara, 385 metres above sea-level. Four kilometres further north-west is another hill, of nearly equal height, but of black aspect, called Adatalob Hadal. West of Ti Keferiai, at distances of five and a half and nine and a half kilometres respectively, are two conspicuous little hills rising from the plain, one on either side of the Wadi Didaut; these are called Kikeiyet Sharqi and Kikeiyet Gharbi.
East of Ti Keferiai is a great sandy tract stretching to the Wadi Di-ib, from which low hills rise half swathed in blown sand; the principal hill groups bear the names of Gebels Tishushi and Tishushi Tiboki.
Qara Saba is a high and steep hill mass of dark aspect, rising conspicuously to 788 metres above sea, between the Wadis Didaut and Baueiwai, some sixteen kilometres south-west of Ti Keferiai. The tract between Qara Saba and Ti Keferiai is a waste of blown sand through which low hills protrude in places.
Adar Aqdeib, a granite hill 736 metres high on the north side of the Wadi Didaut, about half-way between Qara Saba and O Shakafa, is a landmark for two small water sources and a pass. The first of these water sources, Megwel Adar Aqdeib, is on the east side of the hill, in a little tributary of Wadi Didaut. The second, Megwel Didaut, is at the head of Wadi Didaut itself, in a separate rugged hill tract south of Adar Aqdeib. The west faces of Adar Aqdeib are drained by the Sarob Kwan, half of which courses south-east to Wadi Didaut, and half north-west to Wadi Meisah, and the divide forms a well known easy pass.
