Found this while derping around travelling to quest location and I thought I'd take a few minutes to report this bug.
Basically just part of one of the big rocks are not properly aligned to the ground so it looks like it's floating, I've included a picture of it and the location on the map.

It's not a huge bug but thought I'd still post it in case this gets passed on to the developers.
