Notes: The author visited this site on 25/06/2018. A semi circular group of mounds can indeed be seen but these mounds are like the mounds all over Cox Tor, White Tor and Roos Tor. These mounds are probably periglacial. An alternative explanation of these mounds is the activity of the yellow meadow ant (Lasius flavus). Whilst the ants can use stones (natural or ring cairn) to initiate their mounds they are not required. Whichever explanation for these mounds is correct it seems most likely this site is a natural occurrence that happens to look like a ring cairn.

"A semi-circular bank, possibly the remains of a ring cairn.1.4 to 2m wide, 0.4m high. Composed of small + medium sized stones now largely turf-covered. It fades at each end of a near-perfect semi-circle of 14.9m internal diam. There is a low stone pile, 0.2m high, in se quadrant".
