Maraldi, a 45 km impact crater, was shown in its regional context
in figure 50. Its rectilinear shape is in striking contrast to the circular
or oval shape of most lunar impact craters. Faulting along northwest and
northeast planes, probably generated by the Imbrium event, is the cause
of the unusual configuration of its walls. Debris aprons form a narrow
but continuous terrace along the base of the crater wall. The high rate
of mass wasting on the steepest slopes is proven by the low density of
craters superposed on the crater walls in contrast to that of the much
younger mare surface in the floor of Maraldi. Ultimately, as depicted near
the north edge of the picture, landforms evolve toward rounded forms partly
buried under their own debris aprons.
