Considering the time and distance between us and Charon it is incredible to have access to such information that provides a detailed history of what has happened on and below the surface of this moon.

The team thinks that an ocean under the surface of Charon could have frozen long ago leading to an expansion that created a major resurfacing. The video below gives a detailed view of Charon's surface from a digital rendering.
