Rhiannon,
re your latest posting.
I have 2 photos of the bluestone in the grounds of Heytesbury house which Cunnington owned before the stone was taken to Salisbury museum where it still lives.
What is interesting it that the Fargo Plantation henge revealed pieces of bluetone when F. Stone excavated it in 1947.
Recently Colin Richards has been testing pitting in the area west of the Cursus where Stone reported a bluestone scatter.
Several good sized pieces have already been found and we are now looking at another possible bluestone scatter which I found this week 5M south of Monarch barrow on the other side of Fargo planation.
