About this image

The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations of the surface not easily identified in a single band image. Today's false color image shows part of a crater in southern Terra Cimmeria. The dark blue feature on the right side of the image is a large sand dune complex. Dark blue in this false color combination indicates basaltic sands. 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.
