I know bits of North Hill better than other bits...Trebartha estate is a bit of a no go area I believe, lots of forestry work. I have visited Allabury Iron Age round and spent quite a bit of time on both Hawks Tor and Kilmar. For those of you who don't know they have recreated a bronze Age settlement at Trewortha...i have seen it from a distance but have yet to get there.
The reason I asked about Bowda was just because the grid Ref put it in a field...I will be going up there in the next few weeks because it is to be on part of my circular walk around the moor that I am writing at the moment. I pass by Stonsford Stones Plantation as I head south.
I have not come across the book you found these refs in...Does it have similar details for each parish?
I will contact CAU (or whatever long winded title they have now) and see if they will let us use the photo of Bury Down.
Thanks for the info
Mr H
