I would probe behind the rock wall on the left side , on the slope going down to the creek. Also, I would look for a privy or clean out hole behind the barn ( on the right side of the barn), you'd need to probe for it. I would also try down to the bottom right in your picture, where you wrote " old road", I would look on the RIGHT side of the road, especially behind any large boulders or rock walls. Good luck
