Sand dunes cover this entire area as far as the eye can see.  There are
no landmarks that you can discern anywhere.  The sand is very hot from being
heated all day from the punishment of the sun.  The wind gusts and blows
sand into your eyes.  The sand underneath looks like the waves rippling on
the water.  This is the most desolate place you have ever been to.
