C14 Radiocarbon Dating - Sample - AA-49282

A piece of alder charcoal (Sample T4). from a charcoal-filled pit (Context 1D) located beneath the centre of the recumbent stone (which had been moved to a new position in the late nineteenth century). The pit was cut into the natural subsoil of the hill which had been scarped in order to provide a stable foundation for the monument. There was no trace of a buried soil. The pit was sealed by a substantial deposit of rubble which had buttressed the outer kerb of the platform/ring cairn. The recumbent stone had originally been positioned on top of this deposit. The position and stratigraphic position of this material suggests that the pit had been dug and refilled during the preparation of the site, before the stone platform was constructed.
