Ennedi Plateau

A sandstone massif in northeastern Chad, shaped by erosion into cliffs, canyons, arches, and isolated rock towers. Its caves and rock shelters preserve archaeological evidence, including ancient paintings and engravings.

Aloba Arch: A monumental natural sandstone arch in the Ennedi region of Chad. This landmark exemplifies the plateau’s erosion-sculpted arches.
Sandstone: A sedimentary rock made mainly of sand-sized mineral grains cemented together. The plateau’s resistant sandstone supplies the material sculpted into cliffs and arches.
Tibesti Mountains: A volcanic mountain range in northern Chad and southern Libya, rising above the Sahara. The Tibesti provide a regional comparison for Chad’s major Saharan uplands.
UNESCO World Heritage Site: A place inscribed on UNESCO’s World Heritage List for its recognized cultural or natural value. The Ennedi’s dual natural and cultural significance underpins its international recognition.
Guelta d'Archei: A permanent desert waterhole in a deep canyon in the Ennedi region of Chad. This canyon oasis concentrates wildlife and human activity within the plateau’s dry landscape.
Differential erosion: The uneven wearing away of materials with different resistance to weathering and erosion. Differences in sandstone strength help leave towers, overhangs, and arches standing.
Sahara: The world’s largest hot desert, extending across North Africa. The Ennedi forms one of the Sahara’s distinctive upland landscapes.
World Heritage Convention: An international treaty adopted in 1972 to protect cultural and natural heritage of outstanding universal value. The convention provides the framework for recognizing and safeguarding the Ennedi reserve.
Ennedi Rock Art: Prehistoric paintings and engravings found on rock surfaces in the Ennedi region of Chad. These images preserve evidence of people and environments that predate today’s hyperarid conditions.
Canyon: A deep, narrow valley with steep sides, usually cut by a river or stream. Canyons channel runoff and expose layered rock across the massif.
