Surface features Galileo image of cratered plains, illustrating the pervasive local smoothing of Callisto's surface The ancient surface of Callisto is one of the most heavily cratered in the Solar System. [35] In fact, the crater density is close to saturation : any new crater will tend to erase an older one. The large- scale geology is relatively simple; there are no large Callistoan mountains, volcanoes or other endogenic tectonic features. [36] The impact craters and multi-ring structures—together with associated fractures , scarps and deposits —are the only large features to be found on the surface. [13] [36] Callisto's surface can be divided into several geologically different parts: cratered plains, light plains, bright and dark smooth plains, and various units associated with particular multi-ring structures and impact craters. [13] [36] The cratered plains constitute most of the surface area and represent the ancient lithosphere, a mixture of ice and rocky material. The light plains include bright impact craters like
