In addition to the light-colored mineral deposits located in the
high resolution strip there is also a large number of small, dark-colored dunes.
     Here is a map of some of the dune locations.  There are thousands
of dunes in this area.  Most of the dunes range in size from 30 feet in
length to 300 feet.

The dunes can be roughly separated into 5 major types:

 attached dunes that are lodged up to topographic high features
wandering dunes that are isolated from other dunes
sets of parallel dunes
complex dunes
ripple dunes in dark-filled "lake" craters
