With the latest high-resolution imagery down, it really looks like there is significant topography at the north pole (there certainly is on the horizon). Using jccwrt's work above (rotated to make north up(wards)), it's tempting to interpret this part as a mountain range (perhaps
encircling the entire northernmost area), entering and leaving the field of view on the right side in this image.
It could be a mountain range. My first thought was that it was another large fissure system seen edge on. Of course, at the scale of some of these, there's functionally not much difference!
It is interesting that it is "walling in" some of the darker terrain around the north pole - I wonder if it's either creating a cold trap that keeps the north pole in winter darkness for a little longer.
As for the infilled crater, it looks pretty old and degraded, so there's a possibility that it could just be infilled with ejecta from other impacts. That said it's on relatively flat terrain so there might have been some mare-like flow into the crater. Hopefully we'll get another hi-res image to get some context to the eastern rim of that crater.
This crater (directly north of Moat Mountain) looks interesting, could be a potential terrace impact. Looks relatively young, too. Some of the ejecta is covering nearby tectonic features.
