QUOTE (Stu @ Jul 6 2010, 01:52 PM)  ...Cape York... in colour... ... This is a great picture, with fascinating geology going on. For instance, being a crater rim, I would not expect neat layering; I find it difficult to explain the "ringing" about Cape York in a manner other than waterlines. I see at least 4 major levels. I'd love to see this in 3D. At the upper end there is a steep wedge-shaped incision (see highlighted image below). Note that the wedge cuts through at least two of the "rings", and appears to project a fair distance to the north (?). I'm inclined interpret it as a landslide, but having difficulty with the mechanism; I suppose it could be an eroded fracture. In the highlighted image, the point of the wedge has its origin between the highlighted green and blue rings; this region is very smooth, such that I am tempted to interpret it as the remains of a beach. Sheer speculation, of course  Overall, the northern end of Cape York looks the most interesting, and I very much look forward to a pic from Oppy looking down on the Wedge.
