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.

We could call these two schools of thought, the "Clean Streakers" and the "Dirty Streakers"! Some fence-sitting by Steve Squyres... ""It could be dark sand that has been blown out of the crater," Squyres suggested. "Alternatively, it could be places where there has been selective stripping of fine-grained dust by locally enhanced winds," he pointed out. The MER team is planning a campaign to study one of these streaks, he said, once Opportunity gets over to that area." -------------------- "Ride, boldly ride," The shade replied, "If you seek for Eldorado!"

While I'm still in the clean-sweep camp. The dark sand within Victoria isn't, to my eye, as dark as the streaked surface.
