From above the lines of stones identified as stone rows look like patterned ground formed by periglacial activity. A mixture of stripes (ie. lines of stones) and circles are characteristic of land forms produced under periglacial conditions. This explanation fits the evidence much better than the idea that this represents a multiple stone row of the type only found in Caithness and Sutherland. Excavation would rapidly confirm or refute this interpretation.  The identification of a pair of multiple stone rows (see also Hafod y Dre) in this part of Wales has always been seen as an extraordinary anomaly and the aerial photograph provides an alternative and more plausible explanation. On the basis of available evidence this stone row should therefore be considered as uncertain at best.
