This does not seem to be a constructed structure. However the hill of ‘Mound Rock’ appears to be a possible fixed point for the sunrises progression, with the stone structure a fixed observation point - the sides of Mound Rock give either midsummer or midwinter. The position of the stones give a very good view of the Mound Rock's horizon. This can be used as a four point season forecaster.
At spring or autumn the horizon sunrise will be hidden by the hill. But the angle of the sun rising should position the appearance of the sun at the top of the hill to indicate either spring or autumn. The height of the hill relative to the stone structure is around 190 feet, giving the angle of visible sunrise as per Figure 1.
The line of the two standing stones is closely orientated towards the midwinter sunrise. There is also what appears to be a bank and ditch that runs from the stone circle position towards the midwinter sunrise.
The local ‘hut circles’ and ‘field systems’ together with a sheltered natural harbour indicates a local Neolithic community.
Note, if the stone structure were in any other position it could not be used as a season forecaster.
