Craters on the northern plains of Mars are not usually found at the surface. Typically, they are filled and buried just beneath it. The crater shown in this Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image is an example. The crater is located near 50.3°N, 46.7°W. Dark streaks crisscrossing the scene were formed by passing dust devils. The picture covers an area about 3 km (1.9 mi) wide and is illuminated by sunlight from the lower left.
