The most northern mass of =Gebel Faraid= is the highest, its principal peak, situated in latitude 23° 33′ 7″, longitude 35° 22′ 10″, being 1,366 metres above sea-level. As seen from the north, this mass appears somewhat like an outspread hand, its western peak seeming to overhang slightly like a thumb, while the higher eastern peaks resemble fingers. The name _Mons Pentadactylus_ given to the mountain in antiquity, and quoted by Ptolemy, would appear to have referred only to this northern mass, and not to the Faraid group as a whole. The second mass presents from most aspects the form of a nearly flat-topped mountain with a little peak on it and very steep sides. Its highest point, situated in latitude 23° 30′ 53″, longitude 35° 20′ 25″, is 1,259 metres above sea, and forms a main triangulation point; it is too sharp to support an instrument or even a beacon, and observations had to be taken from an auxiliary station a little distance away from the summit and reduced to centre. In ascending this peak as a survey station I approached it from the west by the Wadi el Abiad and Wadi Abu Ribian, placing my camp close under the mountain, on a sandy plain 450 metres above sea-level and one and a half kilometres north-west of the summit. The climb of 800 metres was steep, but not dangerous, and occupied about three hours. The lower illustration on Plate XIV (p. 192) shows the top of the mountain; the lower of the two peaks is the one occupied for triangulation. The third mass of Faraid is a great expanse of peaks extending over eighteen kilometres north and south and some twelve kilometres east and west. Its highest peak, called “The Bodkin” by the Admiralty surveyors, has the position latitude 23° 28′ 58″, longitude 35° 20′ 35″, and rises to 1,232 metres above sea-level, dominating the rest of the mass both by its height and its singular form; it is a great sharp pinnacle, apparently unclimbable, visible from distances of over 100 kilometres in nearly all directions, and a very conspicuous landmark. South and west of “The Bodkin” are numerous other peaks, some of which have been fixed by triangulation; several of them rise to over 900 metres above the sea, and the whole forms a compact mass across which there appears to be no passage for camels.
