The digging season at The Cairns is nearly over and Martin Carruthers, Site Director and Lecturer at the University of the Highlands and Islands Archaeology Institute, talks us through the penultimate day at the excavation.
Today we started the process of placing the covers over parts of the site. We began in the Area Q/M in the North of the site weighing down tarpaulins with tyres. Nevertheless, we remain in an active digging mode in other parts of the site.
Inside the broch the team have resumed excavating the western area on a sample grid. They are now working on floor/occupation deposits beneath the level of the two successive hearths that have been excavated and lifted. Tomorrow will be the last day when excavation occurs here, so will they find lots of lovely environmental information? And will they encounter any nice artefacts to rival the previous finds such as the Iron Age glass bead and the Roman vessel glass in this area? We’ll let you know…
The slightly wetter conditions overnight (in fact it was misty early on today!) have served to very nicely show the soil colours on the site so in the south extension we have been cleaning this area for final photography. Low and behold more animal bone has been appearing in this area, which has previously been so rich in it. Once the excavation is complete for the season, it will be interesting to take a look at all the animal bone that has been generated by the work in the ditch to try to get some idea of the nature of the processes that this bone has been involved in.
Certainly, we have observed butchery marks on some of the bone but by and large the bone is present in large fragments with minimal processing and it therefore looks rather wasteful in terms of the additional calorific content that has not been exacted from these joints of meat. This has often been read off as an index of relative wealth, as poorer communities are expected to be less wasteful. However, we have also observed large parts of articulated carcasses amongst the animal bone suggesting that there may be other processes at work giving rise to at least some of this bone such as structured, or votive, deposition. The post-excavation work of looking in detail at all this bone will be very interesting, indeed.
Tomorrow will be the last day when any excavation occurs anywhere on site, and most of the site will be covered up by the end of the day, we’ll keep you posted on any last minute surprises (almost guaranteed on archaeological sites!).
