Jebel Marra Volcano Caldera, Sudan

This excellent view of Jebel Marra Volcano Caldera, Sudan, Africa (13.0N, 24.5E) shows the collapsed mouth of this ancient volcano withh two smaller calderas now acting as lakes. As one of the highest regions of the eastern Sahara Desert, the Jebel Marra receives more rainfall than the surrounding desert. The radial pattern of streams flowing away from the highest points of the calderas is accentuated by a large dark colored lava flow. Picture taken from STS-64 (STS032-97-064)
