Bright rays seen radiating from Pwyll in the global image indicate that this crater is geologically young. Beyond this dark halo, the surface is bright and numerous secondary craters can be seen. Images of the crater taken from different angles on the different orbits have been combined to generate a model of the topography of Pwyll and its surroundings. This simulated view is from the southwest at a 45 degree angle, with the vertical exaggerated four times the natural size. The colors represent different elevation levels with blue being the lowest and red the highest.
North is to the top of the picture and the sun illuminates the surface from the northeast.
