MGS MOC Release No. MOC2-518, 19 October 2003

This April 2003 Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows mesas and troughs in the northern Nilosyrtis Mensae region of Mars. The larger mesas are capped by boulders or small knobs which are probably the eroded remnants of a layer of rock. The picture is located near 37.8°N, 282.5°W and covers an area 3 km (1.9 mi) wide. The scene is illuminated by sunlight from the lower left.
