Greg,
Can't be sure but it looks more like a moat around a mound.
Actually looking at it again, it appears 180 degrees is a moat and the opposing 180 degrees is raised.

As you noticed the 2 sides of the crater are very different from each other. Both are raised out of the ground though. Since craters form by a large shock wave there should be no way for half of a crater to end up this different. The left side is small and smooth and the right side is thicker and rougher. If anything the smooth part would be larger because sometimes part of a crater can get damaged and get smaller. Say the crater started off all like the right hand side. Then something had to happen to it to make the left side become thinner and neater. Or say the crater started out like the left side, then something had to happen to it to make it thicker and rougher. Both these scenarios seem impossible to be natural to me.
Another possibility is the changes cam from another force, like the wind. If wind blew material onto the right hand side of the crater it should have left material on all the other objects in the area, but nothing else has material blown up on it, or any additional material on that side.
When you consider this is next to wall like ridges at 90 degrees to each other it is even harder to explain. Also the dunes in the crater look like there was water in it at one stage. If this was used as a dam for example it might explain the alterations to the natural shape.

This is probably cracks, which seems different to the ridges above.

Very interesting images Greg. Would you mind telling me how long ago you acquired the first image? Was it in the first batch of images that jpl made available?
The first image certainly looks very much like what one sees in sat images of areas on earth that are civilized or being used for agriculture.
The image of the dome/ crater futher down might possibly have some openings (upper right area).
