Lego Lord of the Rings -
Right beside the rope there's a cracked brick. Pick up Gimli and throw him at it to open the path above. Once again pick him up, walk through the deep snow and enter the narrow tunnel. Destroy the cracked LEGO brick on the rock ledge to open the path for the rest of the team and also gain materials needed for the bonfire. Build and set fire to it with Sam's skill and the further path will become clear.
