I was able to clear the location by grabing all snowberies on the way up and around the wordwall area as well as all loot on ground, ie. adventur's sword next to him, shield on side of the wall, all skulls and getting the moonstone deposite to the left of the wordwall. Loot in the 2 chests there's a hidden one to the right of the first set of stairs. Stand on the rocks left of the wall and you can miss the deposite it's down the hill a bit. This is the kind stuff you gotta do at several dragon locations to clear them lol.
