A stone cairn on a rock outcrop, part of a low craggy outcrop at the southern end of the flat plateau of Gwaun Cerrig Llwydion. The cairn is 3m in diameter and 0.75m high. The area of the rock outcrop is called Garn Fawr but this appears to be a large marker cairn rather than a burial monument. J.J. Hall, Trysor, 5 November 2008.
