Dunes on Ridges (3-D)

These dunes may be active today, but we haven't yet observed them at significantly different times to measure the movement.

May 24, 2012

These dunes may be active today, but we haven't yet observed them at significantly different times to measure the movement. The dunes are moving from northwest (upper left) to southeast, with the steep slope facing downwind.
