Mourdi Depression

The depression is cited as one of the most important Saharan grazing grounds.^[9] There are numerous rock paintings in the area.^[9] The depression was explored by R. A. Bagnold, a pioneer in desert explorations in 1932. During this first motorized expedition in 1932, he found implements on the northern scarp, dated to the Lower Palaeolithic and Middle Palaeolithic period in the valley.^[7][10] In the piste, next to the depression and in the northern rock formations of Ennedi, are rock arches; the Guela d'Archei and its colony of dwarf crocodiles are of particular note.^[11] Addax, a critically endangered species, is found in small numbers in this depression.^[12]
