mountainous region of west-central Guinea. Consisting of a series of stepped sandstone plateaus with many picturesque trenches and gorges, the region serves as the watershed for some of western Africa's greatest rivers. The Fouta Djallon covers an area of 30,000 square miles (77,000 square km) and averages 3,000 feet (914 m) in elevation. Mount Loura (Tamgue), its highest point (5,046 feet [1,538 m]), rises near the town of Mali. Originating in the Fouta Djallon's central plateau are the headwaters of the Gambia, Bafing (Senegal), Koliba, Kolente (Great Scarcies), Kaba (Little Scarcies), and Konkoure rivers. The Fouta's eastern slopes feed various tributaries of the Niger River; and its extension to the extreme southeast, known as the Guinea Highlands (q.v.), contains the Niger's source
