NOTE: The excavation report gives the location of this cairn as SN 999 992 which is approximately 700m to the south-east of the remains of Carneddau farmstead. I wonder if this grid reference is incorrect and the cairn is actually Carneddau Cairn I PRN6313 located at SN 9899 9979. The finds from this excavation are deposited with Powysland Museum and Montgomery Canal Centre, Welshpool.
