C14 Radiocarbon Dating - Sample - SUERC-2433
SUERC-2433
A whole peat sample (Sample 33818) from the middle of a deposit of peat 5205, filling a man-made cut at the base (west) of the broch. Assessment of the seeds and insect remains from within the peat indicate that the deposit was formed in-situ, possibly around a spring flush, in what was then a grazed meadow, prior to the broch construction.
