Nothing much to add to what Chris says. You can park at the houses further down and walk along an old path heading east. Then walk south along the dry stane dyke, climb over another and the site is reached. There are some massive piles of field clearance here and it wouldn't be surprising if the missing stones are buried here. The other unusual thing is that two of stones stand beside but are not part of the wall. The other stone being further into the field. As for the site record.....
Intriguing site this one. 3 stones in a field, two very flat, one more rounded, set in a very large triangle. RCHAMS list it as Springhill Standing Stone, yet call it the remains of a circle, and schedule only a single stone and a wider area where a second may be. What about the other two? Farmer standing his field clearance on end? I'd like to know.
Worth a visit, the stones are excellent, and the views are, as ever, superb.
Access: On a minor road south of Kirkton of Skene. Visible from the road, which is just wide enough and just quiet enough to park carefully on. Opposite a gate, and 200m across a field. Visit in Autumnn/Winter to avoid growing crops.
