The Treasure Hunt note is in front of the locked shed at Toothchapel.
Kick in the boards outside the church and go inside. There you should see a climb point to go up to.
Up there you can jump up to a small area under the roof. From here you can jump down to get to the center of the church where you can climb up at the very end.
Climb all the way to the top where you throw a molotov to the nest.
Loot the key from the Wolverine, go outside and open the shed door. Loot the stash.
