PIA05695: Gullied Slope


Gullied Slope

Caption:

20 March 2004
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows gullies and debris aprons in a crater near 38.5°S, 174.5°W. Gullies such as these may have formed by running water, carbon dioxide, or dry mass movement processes. Most investigators of martian gullies consider that water, whether fresh or briney, may have been involved. This picture covers an area about 3 km (1.9 mi) across. Sunlight illuminates the scene from the upper left.
