Jack Hall Gang Third Treasure Location
You can find 2x Gold bars under a rock at a lake at O’Creagh’s Run, which you can sell to the Fence for 500 dollars each. After crossing the lake, you can find these gold bars on a little island, as shown in the picture.
Swim over to the southeast grassy side of the island and check out a rock. Investigate it.
