The monument comprises the remains of seven prehistoric round cairns, burial mounds probably dating to the Bronze Age (c.2300 BC - 800 BC) grouped together along the top of a slight ridge. All the cairns are within a few hundred metres of each other, with the central 4 clustered close to one another. Cairn (a) is the southernmost of the group and comprises a low circular heap of stones 11m in diameter and 0.7m high in the centre with some disturbance on the E side. Cairn (b) is the most south-westerly of the central cluster and comprises a circular mound of stones 10m in diameter and 0.7m high with a central depression indicative of past disturbance. Cairn (c) is the most north-westerly of the central cluster and comprises a circular mound of stones 10m in diameter and 0.8m high. The sides are steeply sloping and there are traces of a ditch around the cairn, and there is an elongated disturbance hollow in the centre of the cairn within which a low wall has been built. Cairn (d) is the most south-easterly of the central cluster and comprises a partly turfed mound of stones 8m in diameter and 0.6m high with traces of a ditch on the N and E sides. Cairn (e) is the most north-easterly of the central cluster and comprises a roughly circular heap of stones 9m in diameter and 0.7m high on its E side and 0.2m high on its W side. The stones form an almost complete ring, with a break on the SW side around a slightly hollowed out turf-covered centre. There are traces of a ditch on the NE side. Cairn (f) lies on its own, NE of the central cluster. It comprises a low roughly circular heap of stones 10m in diameter and 0.4m high. The top is flattish and partly turf-covered. Cairn (g) is the most northerly of the cairns, standing on its own some distance from the main group. It comprises a circular mound of stones 16m in diameter and 1.2m high with steep sides and a flattish top. There are two disturbance hollows, one in the centre and one on the E side, and to the W the stones have spread beyond the circle of the cairn and have been formed into a rough shelter.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The features are important relics of a prehistoric funerary and ritual landscape and retain significant archaeological potential, with a strong probability of the presence of both intact burial or ritual deposits and environmental and structural evidence. Cairnfields 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.
