Arak gorges
The Arak gorges are a series of desert gorges located in Tamanrasset Province, Algeria.<ref>Template:GEOnet2</ref> The gorges are roughly 330 kilometres from the city of Tamanrasset. Carved by ancient river activity, the canyon walls vary in height from 250 to 500 m (800 to 1600 ft), and the canyon base is now a dry wadi.<ref name="readersnatural">Template:Cite book</ref>
Despite the extremely dry climate (only 60 to 75 mm of rain per year), hardy desert plants and animals survive in the gorges. Examples include the red-headed rock agama, wheatear birds, and small vultures.<ref name="readersnatural" /> There are no permanent human settlements in the gorges, though stone tools and burial mounds indicate the occasional human presence throughout history.<ref name="readersnatural" />
