Our excavations and sampling last summer at Dall Bay North and Craggan crannogs have yielded their first radiocarbon dates. As with the recent results from Fearnan Hotel, the rangefinder dates have been somewhat surprising, and in the case of Dall Bay North, threw up phases of use of the site which were previously unknown.

Dall Bay North saw a series of radiocarbon dates from timbers taken about 20 years ago that suggested the site was first built in the Early Iron Age sometime between 800-400 cal BC with a later phase in the first millennium AD. Our work in July 2018 aimed to find more timbers associated with the Early Iron Age phase of use. That does not appear to have happened, and everything sampled so far has suggested either early medieval activity, similar in date to what was sampled previously or a previously unknown phase of use of the site in the 1st century AD.

Rangefinder dates from Dall Bay North

Given the trenches we opened at Dall Bay North seem not to contain evidence for activity in the Early Iron Age, we will think carefully about what further work we do with the material sampled from this site. It is clear that Dall North has a more complex site history than previously understood. The environmental evidence from the contexts associated with these timbers might shed light on changes in economy between the Early Iron Age, for which we have ample evidence from Dall Bay South and other crannogs in Loch Tay, and the first centuries AD.
