Frankly, I am kinda hoping that the ripples/dunes on the floor remain undisturbed. Perhaps it is superficial ethics, but to me they are so beautiful it seems a shame to alter them.<br /><br />In a recent interview, Squyres states, "There is a massive, huge crossbed right at the base of Burns Cliff. And it's the kind of thing that you would expect from wind. So we see these 4 meters (13 feet) of sulfates at Burns Cliff, and we see tilted sediments underneath that. We don't think the sediments were laid down flat and then there was tectonic tilting. We think they were laid down at an angle. And when you see sediments laid down on a big scale - meters across - at an angle of 20 or 30 degrees, that says pretty unambiguously that it's a dune."<br /><br />I think he is referring to this area. It indeed looks very intriguing from a distance, but I have seen nothing in the Karatepe area to unambiguously point in the dune direction. I would very much like to see Burns Cliff closer.
