I checked back for your link Crusty, thanks, (missed it as it was from the days I was lurking) and it is (of course) in the right area for the demolished post.
Do you have, or could you get a more precise location by any chance? I know the note on your original post is good, but we are looking for something we now know to be under turf, so any extra pointers at all would help.
I covered the area at the top of the hill in detail, and noted an abandoned, fenced compound adjacent to a cellphone installation, but satellite aerials? Am I in the right place? It was a short way from a demolished sandstone house and a quarry just past it.
Crummy, embarrasingly bad, over the shoulder photo of the abandoned compound follows, is this the location?:
puplegrum, how do you fancy some turf cutting and rolling some weekend or evening
