The monument comprises the remains a burial cairn, probably dating to the Bronze Age (c. 2300 - 800 BC). It is situated in a commanding position on top of the ridge. The cairn is turf covered and measures 14m in diameter and 1.7m high. A small cairn has been built on the top and on the southern side there are several disturbance hollows. On the northern side there is a slight ditch measuring c. 2m wide by 0.2m deep.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The monument is an important relic of a prehistoric funerary and ritual landscape and retains significant archaeological potential, with a strong probability of the presence of both intact burial or ritual deposits, together with environmental and structural evidence. Cairns may be 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.
