'Mound' noted on OS 1:10 000 sheet at the given NGR and picked up during instrument survey.
The mound measures 7m in diameter and 0.5m high. It is composed of large blocks of stone consolidated with heather and bilberry. The mound lies on the crest of a ridge above the SW slopes of Mynydd-y-glog and is probably a sepulchral cairn.
