The head of Wadi Shait is formed by the union of a number of drainage channels from a kind of _cul-de-sac_ formed by Gebels Migif, Ras Shait, and Mudergeg, where it is separated from the heads of Wadi Gerf and Wadi Hafafit by flat sandy divides. Passing in a south-westerly direction to the west of Gebel Migif and Gebel Dweig, it receives as a tributary =Wadi Dweig= (in which are the ruins of an ancient station) on the left. Taking thence a more westerly course it traverses more open country, and then narrows among hills north-west of the remarkable peak of Gebel Abu Khrug. At a bend further on is =Bir Murra=, a shallow well sunk in the alluvium of the wadi floor at the foot of a serpentine scarp; the water here (as the name of the well indicates) is very bitter, and is generally drunk only by camels. After passing Bir Murra, the wadi turns south-west, then curves again near =Bir Um Gubur=, about three kilometres south-east of Gebel Sufra, and about twelve kilometres below Bir Murra. Bir Um Gubur is a shaft about two and a half metres diameter, sunk about eight metres deep in the alluvium of the wadi; it was yielding good supplies of excellent water in 1906. About ten kilometres below Bir Um Gubur, =Wadi Hamish= joins Wadi Shait from the north-east. In the remainder of the course of Wadi Shait to the Nile, the principal water source is =Bir Heliwat=,[84] about ten kilometres below the point of influx of Wadi Hamish, and the chief tributary wadis are Muelih, Beza, and Midrik, all of which join it from the north-east. The upper portions of Wadi Shait contain a fair abundance of trees and scrub, but the lower parts are sandy arid wastes.
