21 November 2004
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows exposures of north polar layered material -- perhaps composed of a mixture of dust and ice--in the form of a hill and an adjacent depression. The depression is in the lower half of the image and forms an oval shape at its lowest elevations. The hill is immediately above the depression (above the center of the image) and forms a similar pattern of arcuate bands. This scene is located near 85.7°N, 21.0°W. The image covers an area approximately 3 km (1.9 mi) wide. Sunlight illuminates the scene from the lower left.
