Speed dating

Well, nearly. Only slightly later than promised, I’ve managed to write the second part of the summary of our recent dating project. As well as re-dating the New Laund Enclosure to the Middle Iron Age, these results have also helped us pin down dates for some of the archaeology around the Whitewell Enclosure.


We have one date from the top of the outer ditch, here in trench Q. This is on charcoal from an oak twig at the very top of the secondary fill of the ditch and it calibrates to between 1530 and 1425 BC. This ought to mean that the outer ditch, which of course is now completely buried, was still a visible feature in the landscape in the Middle Bronze Age.

This helps to make sense of one of the important questions about this site. Here we have a complex of lots of pits inside the three concentric ditches of the enclosure. Many of the finds from the pits and the enclosure look very similar but we don’t know if the pits and ditches were in use at the same time, whether some of the pits are earlier than the enclosure ditches or whether the enclosure came first and the pits were a later response to the visible remains of an earlier enclosure (confused yet, I know I am).


This is pit M13, inside the enclosure, which we dug in 2014. A date on a fragment of alder charcoal from the top fill of this pit (just about behind Connie’s head) shows that it was in use in the Middle Bronze Age too, between 1500 and 1405 BC. M13 looks to be a long lived pit with many layers and both this date and the enclosure date are from the end of the sequence. All we can really say here is these things were still visible dents in the ground in the Middle Bronze Age.


Pit N06 should have been the last in the complex of pits we excavated in 2014 in trench N. There are two dates from this pit fill, which cover the whole of the Early Bronze Age. One calibrates to between 2270 and 2030 BC and the later one to between 1745 and 1620 BC.

All of this tends to suggest that the pits and the Whitewell enclosure both begin before the Middle Bronze Age and have a long sequence. This makes it much more likely that, unlike what appears to have happened at the New Laund Enclosure, the worked stone tools (which seem to be Neolithic and Bronze Age) go with the excavated features.

Thanks to Denise at Oxford Archaeology (North), who identified all the wood in the first place, Oxford Radiocarbon Accelerator Unit and Beta Analytic Inc, who did the actual dating, and the Natural Environment Research Council and University of Central Lancashire, who paid for it all.
