Sand Slide (EDM - Absolute Natural Colors; credits for the additonal process. and color.: Dr Paolo C. Fienga - Lunar Explorer Italia)

Sand Dunes are found in numerous Regions of Mars. These Dunes are in the North Polar Region: high latitude dunes are covered seasonally with Carbon Dioxide - CO2 - Frost (such as dry ice frost).

This edm shows a place where material has slipped from the crest of the dune and slid down to form a deposit at the bottom.
The material may have been loosened by the activity associated with sublimation (evaporation from a solid to a gas) of seasonal frost.
