The area is notable for its prehistoric rock carvings, first reported by the Egyptian explorer
Ahmed Pasha Hassanein—the discoverer of Uweinat, who in 1923 traversed the first 40 km of the eastern side of the mountain, without reaching the end. Engraved in
sandstone, thousands of
petroglyphs are visible, representing
lions,
giraffes,
ostriches,
gazelles,
cows and small human figures. According to a technical report of
UNESCO, "Thousands of rock art sites of different styles and themes are distributed all over the area, [attesting] to the development of early pastoralism in Africa and exchanges among different ethnic groups across the Sahara." ==Geography==
