This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows layered material exposed on a slope in the north polar region. An unconformity is visible in the middle/upper left of the image, where layers are abruptly truncated. Unconformities are indicators of drastic change in the region-the lower layers were deposited first, then eroded, then the upper layers were deposited.
