Aish Ridge

Using O.S outdoor leisure 28 map park at very small grass layby at SX684603 directly opposite is a bridle path that leads to Ball Gate , half way along on right hand side is Aish ridge access land .Spotted this one on the way back from Corringdon Ball in total 14 stones, quite large in comparison to other stone rows on the moor in height & width . This only warrants 2 dots on the O.S map so I am unsure of its antiquity, can anyone shed any light?
