Yes, that is my guess.
I was doing a where was Farnsworth killed tour (like I know). I first stopped at the Devils Slipper, then down to the this area. I wanted to walk to the Slyder Farm but I had an older guy with us and he wasn't up to that much walking. We lingered right at the path where it cuts through the stone wall but I don't remember what the wall looked like on the east side of the path.
What's funny is I took the guys out Howe/Wright Avenue as they were never out there before. Of course I had to get a picture of the porpoise rock formation that made it on a past Where is it post?
