North Polar Layers
Caption:
2 January 2004
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a depression eroded into north polar layered materials located near 86.1°N, 30.8°W. The layers in the north polar region have been considered for more than 30 years to be composed of dust and ice, although this cannot be confirmed without sending a person or robot to investigate. This picture covers an area about 3 km (1.9 mi) across. Sunlight illuminates the scene from the upper left.
