This image spans from wall to wall across the center area of an impact crater in Utopia Planitia. From what we see, a lot has happened to modify the appearance of the crater since it was formed.
First, the crater is no longer deep and bowl like: it is shallow and generally flat across its interior, indicating it has been filled with material. The small-scale relief features of this filled surface give clues as to what has happened. The parallel wavy ridges suggest that the material was able to move and flow, perhaps in several successive stages, and likely due to the presence of ice in the ground.
