About this work
This image was acquired on January 2, 2014 by NASA's Mars Reconnaissance Orbiter. Dune fields located among canyon wall slopes are also known as "wall dune fields" and are further identified as either climbing or falling. Falling dunes are defined as large bedforms with lee faces on the downhill side-indicating that this is the direction of their migration-and on moderate slopes greater than 10 to 12 degrees.
