FIG. 76.  Air photograph of eolian dunes in the Namib desert, Namibia, photographed by Tad Nichols.  Like the dunes that are inferred to have produced the bedding in Figure 75, these Namib dunes have two sets of dunes superimposed at approximately 45 degrees to the main dunes.  The set that is best developed is migrating from right to left and toward the viewer; a second set is migrating from left to right and toward the viewer.  Height of the main dunes is approximately 100 m.
