The monument comprises the remains of a burial cairn, probably dating to the Bronze Age (c. 2300 - 800 BC). It is c.22m in diameter, c.58m in circumference and rises to 2m above ground level, though it has been much rearranged by shelter construction. It is the middle one of a group of three on an upland summit plateau at c.750m above OD. An OS triangulation pillar stands on a concrete slab on the top.

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 be 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.
