of the oasis town of El Kharga in Egypt. The town and the dark
patches of agricultural land are bracketed by two corridors of fast-
moving barchans dunes coming from the north. At upper right is the

airport runway (which is notably aligned in the same direction as the
dune migration, so that planes can take off and land into the wind): the
barchans cross the road, requiring clearing efforts. For nearby
barchans viewed from the air, see Fig. 6.5 . Photo NASA/JSC/EOL
