The summit cairn remains, very large and impressive although it clearly has been extensively rearranged. The smaller cairn to the SW has been more or less levelled although it is still quite clear where it was. Both cairns have large walkers' wind shelters, and the levelled one has a small modern cairn at its approximate centre.

The monument is of national importance for its potential to enhance our knowledge of prehistoric funerary and ritual practices. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structures themselves may be expected to contain archaeological information concerning chronology and building techniques.

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