The Acacus Mountains are a mountain range in western Libya, part of the Sahara. Situated east of the city of Ghat, they stretch north from the border with Algeria, about 100 kilometres (60 mi). The mountains have a large variation of landscapes, from different-coloured dunes to arches, gorges, isolated rocks and deep wadis. The area has a particularly rich array of prehistoric rock art.Photograph: Pir6mon
