Sue Dyke, volunteer archaeologist at The Cairns and soon to be student at UHI Archaeology Institute, describes the exciting day on site….
We start with a quick tour around the site! Over in the South extension (the area most exposed to today’s high winds and therefore coldest corner of the site!) our stalwart diggers have started to take a section through the broch-period ditch. Excavations of previous broch ditches have often proved rich with deposits, sometimes deliberate deposits associated with perhaps a decommissioning/closure events… so expectations are high for the ‘ditch to be rich’!
Today’s haul of finds included animal bone and pot sherds. The section has revealed a few bands of stone high up which may be indicative of 19th Century rig-and-furrow (a post-medieval cultivation technique) in this area which fits nicely with a copper coin found by one of our summer school students here. In another part of this section though a massive cattle scapula turned up. Carefully working the soil around it Don managed to reveal most of it by the end of the day, and there seemed to be other bones associate with it also.
The other group working in the south corner are extending a sondage (the word is from the French ‘to take a sounding’) and continuing to remove deposits against the south side outer broch wall, the stratification in this area is complicated and so the team are proceeding carefully one layer at a time. Finds today consisted of some slag and bone.
Moving around the broch clockwise (hard going today as that’s directly into the wind!) we come across the team excavating the northern part of Structure B. This area revealed an area of paving which appears to indicate further later Iron Age structure including a nice wall pier, just outside the north edge of the broch. Finds included a small amount of bone.
Meanwhile today’s ‘intra-broch action’ takes place in the north-west quadrant of the interior. Therese has been sampling the ashy rake-out deposits from the hearth, while Gary and Ole have been recording the section through a very large pit in the north -west quadrant. Ross has started sampling floor surfaces and Kath has her planning square laid out in the centre of the broch. Analysis of the bone/charcoal/seed/charred grain/microfauna/whatever contained in samples from the excavation will be taking place at a later date.
Saving the best till last (my home trench!), Bobby’s Chain Gang have worked tirelessly to continue to remove the baulk between area’s Q and M (these are situated downhill towards the end of the site … more sheltered from the wind than the other trenches). Removing the baulk will clarify the site and further define the wall features that are emerging. A lovely wall with large beach cobbles lining the top looks to be curving in a south easterly direction. In the area just behind the baulk (nearer the broch) there’s a possible revetment wall of a later building and work today has nicely revealed the shape and form of this.
The ‘find of the day’ made late in the afternoon by Catherine from the group of Masters students from Stirling University definitely goes to Trench Q. Excavating in the aforementioned later revetment wall building, Catherine found a very well-preserved beautiful bronze ring!
