Under one of these they found hazelnut shells - which may sound unimportant except that these shells can give excellent radiocarbon dates.
Lead archaeologist Ollie Harris admits that it's been a complex site to work on, and that interpreting what they've found hasn't been easy. There is plenty of evidence along the ridge of metal working - they've found hammer and burnishing stones - but, as they've worked downwards, it seems that what they are finding is a site which was only occasionally occupied, perhaps during the summer, and may have had a variety of craft industries rather than just metalworking.
The most intriguing aspect of the site is that it would have been visible for miles, both inland and out to sea as far as the Small Isles, so they must have had very good reason for such deliberate, and perhaps risky exposure.
We look forward to welcoming members of the Ardnamurchan Transitions Project back to Swordle next year.
