The monument comprises the remains of three burial cairns, probably dating to the Bronze Age (c. 2300 - 800 BC). The monuments are located on adjacent hill summits and consist of stone cairns, roughly circular in plan. The southernmost cairn is located on its own and measures 20m in diameter and 2m high and is composed of large boulders. There has been substantial disturbance in the centre of the cairn, with the construction of a small rectangular shelter measuring 2.8m long by 2m wide and 2m high. The shelter has an entrance in the N wall with the lintel still in place. The two further cairns are located close together on an adjacent summit. The E cairn is 20m in diameter and 2m high with four hollows and two walkers cairns on the top. The W cairn is 16m in diameter and 2m high and has two hollows and a walkers cairn 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 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.
