The monument comprises the remains of a burial cairn, probably dating to the Bronze Age (c. 2300 - 800 BC). The cairn is slightly oval in shape and measures 20m by 15m and 2m high. It is constructed of stone and situated on the west side of the Afon Tarell, on a sloping valley side above a waterfall. The stony composition of the cairn is clearly visible through the grass cover and a shallow depression on the summit of the monument suggests ancient disturbance.

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.
