From time to time, the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) catches -- in action -- an afternoon dust storm, dust devil, or other dust-raising event. The dust-raising event shown here, probably the result of a sudden strong gust of wind, occurred in November 2003 in a crater located near 57.5°S, 60.6°W. Sunlight illuminates the scene from the upper left, so the dark area below the dust plume is its shadow. The picture covers an area about 3 km (1.9 mi) across.
