Western (Libyan) Desert

Egypt's Western Desert covers an immense 700,000 square km of land to the west of the Nile and accounts for about two-thirds of Egypt's land area, stretching all the way from the Mediterranean Sea down to the Sudanese border.

While quite desolate, the desert is far from featureless with plateaus reaching 1,000m high and various interseting rocky escarpments (ridges) and deep depressions (basins) though of course no rivers or streams of any kind. Human life is only sustained in limited pockets around desert Oases such as Siwa, where ground water provides for limited agricultural production.
