As you can probably work out from the name, I'm not sure about these stones. For two reasons:
1) They are low, no more than half a metre.
2) I've never seen any mention of them anywhere, despite the area having been quite popular with antiquarian/rock art spotting/archaeologist type people (and golfers).
In defence, I must point out that they are conspicuously placed on the ridge, near shedloads of rock art, enclosures and a small circle. Furthermore, they display erosion patterns that indicate they've been stood up for very long time. Similar amount of erosion as the stones of the circle. The grain of the stone is perpendicular to that of the bedrock outcrops the nearby RA is pecked onto, so I don't think they've gotten like this of their own accord.
Happily, they are within easy reach of the path that marks the east edge of the golf course.
