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)
