21 Natural Rock Formations That Look Like They Belong on Another Planet
20. Ennedi Plateau, Chad

Hidden deep in the Sahara, Chad’s Ennedi Plateau is a gallery of natural rock arches, towers, and labyrinthine canyons carved by wind and water over millennia. It’s a landscape that feels untouched by time—remote, reverent, and wildly imaginative. The sandstone formations resemble petrified waves and wind-swept sculptures, many of which are adorned with ancient rock art. Guelta d'Archei, a remote oasis here, is famously home to a population of desert-adapted crocodiles. It’s a region so surreal and sacred it borders on mythical, blurring the line between nature’s architecture and a forgotten civilization.
