This image from NASA's Mars Global S shows a steep slope in the north polar region of Mars. The stripes indicate an exposure of layered material; the variations in brightness are the result of varying amounts and textures on seasonal carbon dioxide frost.

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a steep slope in the north polar region of Mars. The stripes indicate an exposure of layered material; the variations in brightness among the stripes are the result of varying amounts and textures on seasonal carbon dioxide frost. At the time the image was acquired in June 2006, the carbon dioxide frost was beginning to sublime way, leaving a variety of different patterns in frost distribution.
