Neville did a good photo comparison video of this feature at the foot of Mt Sharp today. Some questionable terrain feature differing photo match ups were discovered. This is why I mostly feature images from the Navigation Camera. My thought has always been, that since this camera is used to plan the rovers drive the image is less likely to be monkeyed with. Perhaps a different team with a different agenda has control of Curiosity’s mischievous Micky Mouse Mast Cam.
