Terraced Wall Crater

Today's image shows an unnamed crater located in Arabia Terra. The small crater seen in the image is located on the floor of a much larger crater. The details visible in the crater indicate that it is a relatively youthful crater exhibiting pre-erosion morphology. This crater shape is a central peak with two rims that are close together. The inner ring is actually part of the original rim that slumped downward during the impact event. The inner rim is mostly a flat terrace, giving this a crater morphology type the name terraced wall crater. Small dark dunes are visible in the lower left corner of the image.
