Stony Creek Cave is a dungeon in The Elder Scrolls V: Skyrim
Stony Creek Cave is found to the Southwest of Windhelm, closer to Eastmarch Imperial Camp. Head inside to start into this short cave. Go to the right and head up the wooden ramp that the bandits inside have erected. Follow it along the small stream. You will come across at least one or two Bandits or Bandit Highwaymen along your path. When you come to the first right-hand turn, take it.
Go around the first corner and start to the North carefully. There are a few bandits in the room and a tripwire trap just in front of the exit from this small tunnel. The air will shimmer a bit to show that there is flammable gas there. If there are still Bandits in the cave, do not ignite it if you are trying for stealth. It will alert all bandits and make stealth much harder to pull off. Sneak in, if you are after that, and ambush the Bandit Thug who is the boss in this cave. You will find an Unusual Gem sitting on the right-hand table against the back wall on the left-hand side. On the right-hand side of the same table is the Illusion skill book: Mystery of Talara, Part 4. The chest with Finn's Lute is to the West of the entrance of this chamber
If you continue to the North to the end of the creek path, you will find a waterfall, a pond and another Bandit. Deal with the bandit and search the area. You will find a locked chest (Apprentice level) and a skeleton or two to loot.
