This image, approximately 500 by 500 meters, represents a popular monitoring site; in this case a sample of the South Polar layered deposits (SPLD).

These deposits are quite extensive and partially surround the South polar residual cap. In this beautiful enhanced color image we see fractured bedrock partially coated in carbon dioxide frost.
