Description
28 August 2006
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows layers exposed in a trough in the martian north polar region. At the time the picture was acquired, the entire scene was covered by seasonal carbon dioxide frost. By late spring and into summer, these layers would appear darker, once the carbon dioxide frost sublimes away.
