The Drunken Lizard Pub

I'm lost trying to find either the entrance to the mines, or a wolf cub, it's cold and i keep dying

Did you flag the QuickTravel spot for Durnore? You can just QT back there and wait out the blizzard... if it doesn't disappear in the interim.

ice cubs

try southwest of the original entry point / wagon master

hammerhold

try northwest of the town, but remember what the dwarf said use the servants entrance (around back)
