C14 Radiocarbon Dating - Sample - AA-24957

Scottish Radiocarbon Database

AA-24957

A single piece of heather charcoal from a charcoal spread under B134, the line of stones running from stone 44 (at B117, natural soil build-up). Its ultimate origin is uncertain. It could have come from clearing out of the chambered cairn. It gives a TPQ for the line of stone B134. Since it is a single twig it probably has not been moved around a lot.
