Dust Event MGS MOC Release No. MOC2-737, 25 May 2004, 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 degrees S, 60.6 degrees 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.
