Several stone cairns situated in prominent upland sites once contained the cremated remains of probably important individuals. The ashes were placed in earthenware pots inside a small chamber called a cyst then covered with a mound of stones. Carn Pica above the Talybont reservoir is a typical example where a cairn has been made into a visible small conical structure in recent times. A pile of stones on a high point to the east on the Bryn is a more accessible example.
