About this image

Today's VIS image shows a dune field on a crater floor in Terra Cimmeria. Dunes at high latitudes - near the polar caps - are affected by seasonal frost and ice. The interactions with frost/ice reduces the amount of movement of sand grains within the dunes. This changes the morphology of near polar dunes when compared to dunes at lower latitudes where ice/frost do not occur as frequently. This crater's latitude is 68 degrees south of the equator.
