On the left, we seem to see half of a former pool that's drained away,
leaving a set of concentric "bathtub" rings. Is that real?

Brian,

I have trouble seeing what you mean in the normal-size image.
When I zoom 200%, I think I can see what you mean; but I also
see what looks like a lot of image artifacts. I think I need to
see what the pros can do with image enhancement.
