The monument comprises the remains of three burial cairns, probably dating to the Bronze Age (c. 2300 - 800 BC). They are located on an upland plateau forming the top of a north-south ridge.

Cairn A - This cairn is located 50m north-east of the standing stone known as Carreg Bica (GM382). It comprises a pear-shaped stony mound 21m long by 14.3m maximum width and 0.6m high.

Cairn B - This cairn measures 0.5m high by 17m in diameter.

Cairn C - This cairn measures 0.3m high by 14m in diameter.

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.
