The monument comprises the remains of a burial cairn, which probably dates to the Bronze Age (c. 2300 - 800 BC) and which stands on a natural rock shelf in open moorland. The cairn is stone built and measures about 15m in diameter and is approximately 2m in height. Other cairns are intervisible to the west.

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. 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.
