They identified those layers as the pre impact surface / sub surface, only a few metres above the Burns formation level, so I don't think we could reasonably expect to see it high on Solander. The interesting thing is that Larry Crumpler's LPSC paper identifies that the unconformity between impactites and the pre-impact surface had a dip of some 11 +/- 2 degrees towards the crater centre. This correlates quite nicely to Parker and Bills paper hypothesising that the bench does in fact reflect a previously level coastal geomorphology and there was subsequent tilting towards the crater. Circumstantial, but worthy of thought.
