Summary
| Description | Astronaut photo of w:Gebel Edmonstone, Egypt. Image has been processed to enhance color variations in the various rock and soil units. The color variations reflect differences in composition (or weathering) of the various rock units. The limestone unit capping Gebel Edmonstone and the adjacent scarp ranges from white to gray in color, while the underlaying fine-grained sedimentary layers are blue-gray. Hillslope pathways for sediment movement downslope are clearly visible as brown to tan streamers originating from Gebel Edmonstone. Barchan dune fields are also visible in this color-enhanced image (lower left), and are distinct due to their mineralogical composition. Evaporite deposits are bright white (center top), while vegetated portions of the Oasis—mostly agricultural fields—are dark blue-black. |
