Description
18 May 2006
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows neighboring networks of gullies in the northwest wall of a south middle-latitude crater west of Hellas Planitia. The faint crisscrossing streaks, also observed on the wall of the crater, are evidence of passing dust devils, a common phenomenon in this region. The gullies might have formed by erosion caused by running water, mixed with debris.
