Dall Bay South Crannog has already revealed a range of key features we will be sampling as part of attempts to more precisely date the Early Iron Age crannogs of Loch Tay.

Excavation began in earnest on Tuesday and as soon as the stone capping of the crannog mound was removed, timber and organic features were found. These included a series of exceptionally large, presumably oak (but maybe elm), vertical piles. These large piles measure around 60cm in diameter, substantially larger than any pile so far discovered at Oakbank. Amongst the vertical and horizontal timbers found so far in the 2×2 trench, was found a layer of ash with lots of charcoal. How these features all relate to one another is yet to be revealed, but will hopefully come into focus over the next day or so.

We are also looking towards the top of the mound where there are timber features exposed on the surface of the mound. Only excavation will reveal how these features relate to each other, or indeed if they are even part of the crannog structure.

Regardless, it is clear that the Dall Bay South Crannog is going to give us a wealth of material to sample and date the structure. We have lots more work to do at Dall Bay South, so look out for more updates, photos, videos and 3D models.
