We visited the site on 16.09.10. It was certainly at the coordinates given by Greywether and we followed the path on the OS map though there are several others within yards. Still it's hard to square our pics with his and Pigmyshrews. Several intervening years, a different season and some wanton destruction may explain this.
Several large stones around the edge, that from the weathering evident on their tops had once stood for centuries, had been fired and split - possibly only a few weeks before our visit as the smell of burning was still faintly noticeable. A very sad sight indeed so only a few pics of the damage are shown here.
As you can see from the pics these are right beside the road (A701) between the M74 junction and the village. They are marked on the OS map. You can legitimately park by the fence at the entrance of the small road 175 yards before and on the opposite side of the road from the stones. From there you can walk along the pavement and across to the stones. In summer long grass can partially obscure the stones - see pics.
On our visit in July 2009 as well as the fence to keep animals out a circle of grass had recently been cut around the inside to emphasise the circle dimensions. A close inspection round the turf of the cut area revealed several large half- buried stones that may have been part of the original circle - see the pics in the 'extreme stonefeelers' link below. The recumbant was piled around with large stones. So the original stones may still be on the site plus additions from field clearance.
Despite the visible evidence that someone attempts to look after this monument it had also been poorly used by others. Lots of old agricultural fencing and plastic sheeting had been thrown over the recumbant and elsewhere. Shame on the culprit.
