The University of the Highlands and Islands Archaeology Institute, in partnership with the Yarrows Heritage Trust and ORCA Archaeology, have completed their first week of excavation at the community dig, near the Burn of Swartigill.
Rick Barton, project officer with ORCA Archaeology, talks us through the first week at this intriguing dig in Caithness, Scotland.
We are at the end of the first week of excavation at the Burn of Swartigill. The covers and tyres came off to reveal that the site had survived well over the winter. The team wasted no time, extending the trench to the east and west to further explore the extent of the structural features present.
So far, we have made some interesting discoveries about the nature of the site. Structure A, the passage around the north side of the site, widens out on the east side, while to the west, it terminates in a small rubble filled cell.
In the centre of the trench, we are further defining the shape and form of Structure B, which appears to be a squashed rectangle in shape. The hearth in the centre of the structure, initially encountered during last year’s excavation, appears to be a later feature. The hearth setting overlays rubble, which appears to be the post abandonment infill of the building.
The ashy deposits from the hearth mingle with peaty layers within the structure, suggesting that after the building was abandoned, it was open to the elements and people still used the shell of the building as a shelter – perhaps as a seasonal shieling, a temporary shelter used while pasturing animals. The remains of the structure continued to gradually collapse around them. This may also account for the presence of a distinctly Viking or Medieval looking whetstone, recovered in a previous year’s excavation on the site form rubble overlying this structure.
The site was then inundated with alluvial soils, deposited by the adjacent watercourse over several centuries, covering the structures. On the east side of the site, this overlays a paved surface, which may represent a yard outside Structure B.
Elsewhere in the trench we are preparing to sample more of a deposit that appears very rich in charred organic material. Hopefully the analysis of this deposits will give us some valuable information about the sort of activities undertaken on the site during the Iron Age, and the lives of the people who lived there.
The Archaeologists will be on site until Thursday the 29th of August and then back on site from Tuesday the 3rd of September until Sunday the 8th.Come along to the see the site, and even have a go at excavation – no experience is required.
