The description in Coflein reads:
"Two cairns set in close proximity on the slope of the Cefn Penagored ridge. Both cairns are about 6m in diameter but are of different forms. The upper cairn has a clearly defined structure marked by a prominent ring of large stones, some over a metre in length. The lower cairn is dedined by an earth and stone bank which includes a large quantity of white quartz. Ther is a small stone lined cist at its centre."
