Here's one of the best renditions I've found so-far: http://photojournal.jpl.nasa.gov/jpeg/PIA07740.jpg Nice and large on the screen. Note how the whole central area appears to be the remains of a highly eroded crater, almost as large as the moon itself, with a subtle central peak. You can just feel that the body is mostly ice, from the visual appearance. I've seen snowfields on mountaintops in summertime that resemble that surface. __________________________________ Start your day with Yahoo! - Make it your home page! http://www.yahoo.com/r/hs
