This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a favorite among the MGS MOC operations team at Malin Space Science Systems, another example of the grooved dunes in Herschel Crater. The fine-scale grooves on the sand dune surfaces were formed by wind erosion. The sand dune surfaces have, over time, become crusted and the dunes immobilized. Wind now has to scour sand from the surfaces of these bedforms, creating small wind erosion features known as
yardangs
in the sand.
