Charon's Mountain in a Moat?

At one of the press events they say that there is better imagry of that part of Charon, so I hope we get to see what exactly that is.

Me too. I sure am not an astronomer but that looks super odd.

To me it looks like isotastic rebound from an impact crater into a surface less dense than rock. If Charon is mostly ices, the impact probably melted a great deal of that area, then created a central peak that due to the weird surface looks different than what we see on the moon and Mercury. Pure speculation, but that is my guess.
