The Cairn is included in an upland survey conducted in 2005. It is situated on the edge of a west-facing ridge of Allt Gwydelyion. A pile of roughly coursed rubble with some pieces of white quartz, the feature measures 2-3 metres in diameter and reaches up to 0.4 metres in height. Although clearly visible, the cairn has poorly defined limits. See survey report Tywyn Dolgoch, by M.J. Roseveare, ArchaeoPhysica Ltd.
