The SIR-C/X-SAR radar system has advantages over visible and near-infrared imagery in that radar is sensitive to surface roughness and orientation and has limited capabilities for imaging beneath sand. Hence, the SIR-C/X-SAR imagery is more sensitive to geologic structures and is especially useful in hyperarid and poorly known regions such as the Sahara

H. G. Lyons, The Physiography of the River Nile and Its Basin (Survey Department, Cairo, Egypt, 1906). Lyons relays a report by Ball that the position of flood marks of the XII Dynasty near Semna along the second cataract stretch (now flooded) indicates about 8 m of erosion over the past 4000 years.

The Nubian Swell is a region of shallowly buried and exposed basement that extends E-W along the Egypt-Sudan border as far as J. Uweinat, 600 km west of the Nile. Only the eastern oart of it is shown in Fig. 1.

W. F. Hume, Geology of Egypt, part I, The Metamorphic Rocks (Government Press, Cairo, Egypt, 1934). Hume's geological reconnaissance of several of the islands in the fourth cataract stretch, which he reached by swimming through the rapids on inflated skins, remains the basis for our geological understanding of this region.

We thank the Geological Research Authority of the Sudan for their help, D. Amesbury for bringing our attention to the shuttle photograph of the fourth cataract stretch, and K, Burke and W. Bosworth for their ideas on the problem. Supported by NASA through subcontracts from the Jet Propulsion Laboratory. This is University of Texas at Dallas Programs in Geosciences Contribution 846
