Thats interesting about those extra stones Rhiannon, Jodie Lewis surveyed Wick Burial chamber, but its in S.Glos. not N.Somerset; emailed about the red ochre which she did'nt know about but can be added to her list of interesting materials.. like the haemetite at Priddy Circles. Such a lot has disappeared from our area, and is also IN the processing of disappearing because they are not scheduled..
