Over the past day and half work has moved from Trench 1 located at the bottom of the crannog mound to Trench 2 on the top of the crannog. While Trench 1 revealed lots of good material for our sampling strategy aimed at refining our dating of Early Iron Age crannogs, Trench 2 is proving to be a little more exciting with a number of features turning up.
We think Trench 2 is located in what would have been in the interior of the dwelling. What we have found is layers of alternatively laid perpendicular timbers. The timbers are all round, although some have been eroded flat, giving the appearance that they had been split or cut to make a flat surface. Between the timbers, we have found layers of ash and organic debris (mostly wood chips, bracken and charcoal).
We also found the timber that was sampled during work in 2005. This timber was 14C dated to 750 BC to 390 BC (95.4%), and appears at this stage to part of the alternately laid horizontal timber arrangement. But the good news is, we can have reasonable confidence that the area we are looking at relates to the Early Iron Age – the period we are most interested in for this project.
This timber was dated during previous work to the Early Iron Age
Beginning on Monday, we’ll have the task of making more sense of how this material relates to each other, and by extension how that translates to the wider crannog structure.
