This wonderful image combines the beauty of the defrosting carbon dioxide ice during the Martian spring with abundant gullies in the wall of a large depression in the south polar region of Mars. Gullies like the ones seen here were a geological surprise when they were first observed in images returned by the Mars Global Surveyor spacecraft. For more information about these gullies, see the image Martian Gullies.
