=Kurdeman= is the name of a low hilly district on the east side of Wadi Ghadir, thirteen kilometres north of Gebel Zabara. It is interesting as containing some ancient mines, doubtless worked for gold. A triangulation beacon has been erected on a hill just above the workings, in latitude 24° 52′ 35″, longitude 34° 41′ 35″, at an altitude of 526 metres above sea, or about fifty metres above the wadi. =Gebel Sabahia= is a craggy felsite hill five kilometres south-east of Kurdeman, rising to 520 metres above sea, or about ninety metres above the wadi. It is drained by the Wadi Sabahia, a tributary of Wadi Ghadir. In the heads of the Wadi Sabahia, north-east of the hill, are some old gold mines. =Gebel Um Tundeba= is a high granite hill near the head of Wadi Um Tundeba. Its summit is 550 metres above the sea. It forms a landmark for the water hole called Galt Um Tundeba, which is situated in a small gully, three kilometres west of the summit of the hill. =Gebel Amba-ut=, seven kilometres south of the foregoing, is likewise believed to be of granite; the southern hill of this group is of a red colour and very conspicuous as one passes from Um Tundeba to Ghadir. =Gebel Ghadir=, the summit of which, in latitude 24° 50′ 9″, longitude 34° 47′ 22″, and 636 metres above sea, is marked by a triangulation beacon, is thirteen kilometres north-east of Gebel Zabara. I ascended it from a camp 424 metres above sea-level in one of the gullies draining westward to Wadi Ghadir. The ascent is easy. The rocks are greenish serpentines and ophicalcites below, with a white quartz felsite above. =Gebel Allawi=, situated on the south side of the Wadi Allawi, is a diorite hill rising to 515 metres above sea. It is best approached by ascending a small feeder of Wadi Allawi, in which a camp can be placed within a kilometre of the summit and 160 metres below it. There are some interesting old gold mines in the quartz veins just below the beacon on the summit of the hill, and a band of graphitic schist crops out near the north foot of the hill. The position of the beacon is latitude 24° 46′ 42″, longitude 34° 49′ 39″. =Gebel Lewewi= is a dark craggy hill range eight kilometres east-south-east of Gebel Zabara, between Wadi Allawi and its tributary Wadi Lewewi. Its highest point, marked by a cairn, is 654 metres above sea-level. There are some old mines in the lower hills two and half kilometres south-east of Gebel Lewewi, and others a little further off in the same direction.
