This VIS image shows the margin between the polar cap and the surrounding plains. There are dunes on the plains at the top of the image. In the upper left corner it can be seen that the dunes have been blown onto an extension of the ice. The rest of the image is dominated by the ice of the polar cap. The polar cap is formed of layers and layers of ice and dust formed over millions of years. The dust allows the layering to be easily visible.

NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Science Mission Directorate, Washington, D.C. The Thermal Emission Imaging System (THEMIS) was developed by Arizona State University, Tempe, in collaboration with Raytheon Santa Barbara Remote Sensing. The THEMIS investigation is led by Dr. Philip Christensen at Arizona State University. Lockheed Martin Astronautics, Denver, is the prime contractor for the Odyssey project, and developed and built the orbiter. Mission operations are conducted jointly from Lockheed Martin and from JPL, a division of the California Institute of Technology in Pasadena.
