Rising 1,640 feet above the savanna of southern Mali, the Bandiagara Escarpment has been home to the Dogon people for more than 700 years. Their mud-brick houses, granaries, and religious sanctuaries occupy nooks and ledges in the rocky façades. Waterfalls plunge from the red-rock cliffs into lush oasis canyons, a landscape somewhat reminiscent of the American Southwest.
