Wondering about the summit one September evening last year, I remembered that some years ago I had noticed a suspicious looking stone lying on a field wall. After some searching I found the stone. Its length/height is approximately 1 -1.20 meters.
On my return the next day and the added bonus of blue sky and much appreciated sun, I took further photos.
And since I presume that this stone once stood upright …
