=Gebel Metawit= is a high granite hill rising conspicuously among much lower hills thirteen kilometres north-west of Bir Shadli. A track leading from Bir Shadli to Bir Metawit and other wells further north-west passes close east of the hill. Gebel Metawit is a good landmark for Bir Metawit, which is situated in the wadi of the same name about three kilometres north-west of it. The summit is 741 metres above sea-level or about 295 metres above the wadi floor at the well. =Gebel Hamrat Mukbud= is a great red granite mass rising from the plain about twenty-five kilometres west of Bir Shadli. Its isolated character and great altitude (892 metres above the sea and about 450 metres above the surrounding country) render Hamrat Mukbud one of the finest and best known landmarks in this part of the desert. A cairn on its summit marks the triangulation point, in latitude 24° 9′ 53″, longitude 34° 23′ 17″. Its ascent is a matter of some difficulty, owing to its great steepness. =El Hamra= is another red granite mass, much smaller than Hamrat Mukbud, lying about half-way between that mountain and Bir Shadli, and separating the Wadi Abu Hamamid from the Wadi el Sheikh. =Gebel Homr Akarim= is a hill about thirty-three kilometres west of Gebel Hamrat Mukbud, close to the north of Wadi el Khashab. Its summit, 490 metres above sea, is marked by a triangulation cairn. =Gebel Marasan= is a range of mountains north-west of Abu Hamamid. It is cut through by an important pass over the main watershed, 685 metres above sea-level, connecting the Wadis Huluz and Abu Hamamid by their respective tributaries Marasan and Marasani, which drain north-east and south-west from the pass. The highest peak of the mountains south of the pass is 1,261 metres above sea-level, while those to the north are lower. The name Gebel Marasan is, however, commonly given only to the peaks north of the pass, as they rise more abruptly from it, while those to the south are unnamed or regarded as part of Gebel Hamamid because the Wadi Abu Hamamid drains their southern flanks. PLATE XIII. [Illustration] [Illustration: Two Views on Gebel Kahfa. (Granite).] =Gebel Khulla= is a range lying a few kilometres west of Gebel Marasan from which it is quite separated. Its highest point is 978 metres above sea. It is drained by Wadi Khulla, a tributary of Wadi Abu Hamamid.
