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.

Location near: 81.1N, 75.2W
Image width: ~3 km (~1.9 mi)
Illumination from: lower left
Season: Northern Spring
