The monument comprises the remains of eight prehistoric round cairns, burial mounds probably dating to the Bronze Age (c.2300 BC - 800 BC).

Item G: Cairn measuring 4.3m in diameter and 0.5m high.

Item H: Cairn measuring 9.5m from north-east to south-west but only 7m transversely where it adjoins a forestry track on the south-east. It is 0.3m in height and a hole in the centre measuring 3m in diameter has a slab 1m by 0.8m and 0.2m thick partially embedded in its south-west side.

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.

The area scheduled comprises the remains described and an area around them within which related evidence may be expected to survive.
