Bié(redirected from Lake Da)
a plateau in central Angola, composed primarily of Precambrian granite and gneiss. In the center the elevation is 1,700–1,800 m; in the north, east, and south the elevation drops to 1,400–1,500 m. In the west the Cerra-Corbo-d’Ándrade Mountains (Mount Moco, 2,610 m) rise above the plateau. The Bié has sparse, deciduous savanna forests and iron deposits. It is an important region for grain cultivation and herding.
