This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a rounded hill, or knob, in the Propontis region of Mars near 43.7N, 189.1W. This knob is a remnant of a former terrain, perhaps the remains of an old crater rim, or eroded upland. Dark specks on its surface may be large boulders. Old impact craters are seen in the lower third (southern third) of the image. The picture covers an area 3 km (1.9 mi) wide; sunlight illuminates the scene from the lower left.
