The monument comprises the remains of a burial cairn, probably dating to the Bronze Age (c.2300 - 800BC). It measures c. 15m in diameter by up to 1.2m in height and sits on the summit of a low, rounded hill. The centre of the cairn has been disturbed in the past and a sheep shelter built into the top of it, although this is now ruined and more stone has been dumped elsewhere on the cairn. An arc of large stones on the N side are probably the remains of a kerb. The stones of the cairn extend beyond this kerb, so that its original diameter may have been more than 15m.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practises. 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 associated archaeological features and deposits.

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