The monument comprises the remains of a cairn which probably date to the Bronze Age (c. 2300 - 800 BC) and is situated on a summit above Blaenpedol. The cairn is built of gritstone rubble and measures 15m in diameter and up to 3.4m high and has a slightly convex profile. It is intervisible with other neighbouring cairns and forms part of a line along the summits of Mynydd Ddu.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The features are an important relic of a prehistoric funerary and ritual landscape and retain significant archaeological potential. There is a strong probability of the presence of both intact ritual and burial 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.
