Wow! If I live to be a hundred, I'll never understand why we've sailed right on past the Beacon toward "Boat Ramp". I agree that the deepest exposures are the most important, but Beacon is the highest! It's sitting right there waiting for us. It's the top of the section. Whether it's composed of impact breccia or undisturbed laminated evaporite determines whether Victoria formed after or before the deposition of the upper Planitia Meridiani. I can't believe that is a trivial issue. It is a fundamental fact of Victoria's history.

I looked back, but I don't see that at Bonneville. From orbit, nothing looks like it's blowing out. From the rim, the dark streaks crossing Bonnevile look like dust devil tracks to me. The one area that might be different is an area of dark dunes under the west wall, but other dunes are lighter, suggesting to me another DD track, or possibly a patch of dark sand like Eldorado, which we do see getting trapped in certain topographic situations.
