This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows an unconformity in an exposure of north polar layered material, at which older layers were cut-off and eroded before a new suite of layers was deposited above them. The terrain in the entire scene was covered by a thin frost of frozen carbon dioxide at the time this picture was acquired in June 2006.
