The monument consists of a stone setting, an arrangement of one or more standing stones where the original form of monument unclear, dating to the Late Neolithic or Early Bronze Age. Originally comprising a standing stone 1.8m high with two other smaller companions, one was standing in 1890 though by 1964 both were prostrate. Only a single standing stone now survives. Composed of Old Red Sandstone his measured 2m in height and 1.7m by 0.2m at the base but sometime after 1999 was substantially damaged; the top 1m is broken off and lost.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The features are an important relic of a prehistoric funerary and ritual landscape and retain significant archaeological potential. There is a strong probability of the presence of both intact ritual and burial deposits, together with environmental and structural evidence. Stone settings are often part of a larger cluster of monuments and their importance can further enhanced by their group value.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
