A very impressive standing stone remains as previously described. It is made from a slice of flat-bedded rock, with its broad sides on the south-west and north-east. It overlooks and dominates the stretch of the valley of the Afon Gain running up to the north-east of it. A number of interesting marks can be seen on the NE face. These are clearest towards the base of the face, where sheep rub means there is less vegetation growth, though there are also a number on the right-hand (north) side of the face, which appear similar to Ogam marks. These appear to be artificial, and do not look like random scratches.

The monument is of national importance for its potential to enhance our knowledge of prehistoric practises. It 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.
