Travels to the Edge with Art Wolfe

It is a fabled land of sand, salt and nomads. But Mali is more than the Sahara; it is a place where the Niger River flows past some of Africa’s unique tribal and architectural wonders. In episode three, Art Wolfe follows the river road to the camouflaged villages of the cliff-dwelling Dogon people; floats downriver to Djenne’s fantastic mud mosque; heads into the desert with nomadic Tuaregs; and finally travels on to Timbuktu where he meets up with a camel caravan.
