In the previous image, and also in the animations showing this region, I'm tempted to say that it's not ejecta that's so bright. This "spot" is resolved to the point that, when not saturating the ccd's, it looks like a pyramidal structure (in shape, not at all suggesting it was artificially constructed) that is definitely lighter in color than the surrounding terrain. It doesn't exactly follow the curves of the crater wall it seems to overly, either.
I'm wondering if this could be a constructional landform -- looks a little like a volcano-like structure in this image, at any rate. Boy, it'll be nice to get better pictures of these areas.
