This VIS image shows part of Olympia Undae, a large dune field that surrounds part of the north polar cap. At the top of the image the dunes are small and isolated. As the amount of available sand increases the density of dunes increases. This is seen at the bottom of the image. Collected during northern summer, the dunes are completely free of ice and frost.
