Go with the Flow

Location: Unmarked cave south of Nick Rye’s location

Once you have this treasure hunt mission in your map, set it as your waypoint so you can locate the marker easily. On the way there, prepare to fight off some bears and wolves. After finding the cave, read the clue then use the zipline in front of the cave to reach a camp by the stream with the key.

From here, you just need to follow the path with the flags or just simply follow the stream until you reach the waterfall. From there, you can rappel or parachute below to find another cavern with a flag marker and a wolf’s corpse outside. Use the key to unlock the gate and loot the goods inside. Treasure hunt complete.
