One of the most striking features of Dione is the bright wispy terrain on the trailing hemisphere. Most of these wisps are radial to the large crater Amata but they are curvilinear and do not resemble crater rays. Some of them are associated with topographic features and this suggests that they are surface deposits of ice outgassed from a global tectonic system of fractures. |
