This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a portion of a trough cutting across a dust-covered plain in the Labeatis Fossae region of Mars. Boulders derived from the layered exposures near the top of the trough walls are resting on the floor, and in some locations, the sloping sidewalls of the dusty trough.
