Jebel Uweinat, Egypt
Rivers of sand sweep around the mountainous outcrops of Jebel Uweinat in this Terra image from 2002. Jebel Uweinat towers
1,934 meters above the barren plains of the Libyan Desert, the eastern third of the Saharan Desert. Located at the intersection of
the Libyan, Egyptian, and Sudanese borders, the Jebel Uweinat highlands foster more rainfall and cooler temperatures than the
surrounding desert, supporting woodlands and shrublands of palms, acacias, Saharan myrtle, oleander, and tamarix as well as
several endemic and rare plant species.
The mountains are remnants of an ancient granitic dome. The western part of the massif consists of intrusive granite arranged in
a ring shape about 25 kilometers in diameter, ending in three wadis (dry, seasonal riverbeds) towards the west. Its eastern side
consists of sandstone and includes a permanent oasis. The area is notable for its petroglyphs. The sandstone provided a canvas for
Bushmen-style engravings of lions, giraffes, ostriches, gazelles, cows, and human figures.
