One writer is calling it "Plutonic tar".

To me, the craters look like the impacts were made in a very dusty environment.   But I am mere amateur so...

I don't think the craters would still be so well-defined if it were dusty, would they?

Take a pile of flour.  Put it in a layer, not real thick.  Drop something in it.  To me it leaves the same type of cratering as seen on Charon.

True, but left on its own, or with any wind, and the sides collapse and soften.
