Looking Into a Trough
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a high resolution view of the floor and walls of a trough located west of the Elysium Mons volcano. The trough cuts through layered and dust-mantled rock. Large boulders and windblown ripples, mostly covered with a blanket of dust, can be seen on the trough floor.
