The first Living on Water dates have now come back from being measured by the AMS. The result comes from the longest lived of a group of three oaks from Milton Morenish Crannog. This group was dendrochronologically matched and identified by Anne Crone as having been felled in the same late winter or early spring.
The wiggle match result puts the felling of these oaks between 370-355 BC.
The wiggle match was comprised of 12 individual 14C measurements through the individual tree.
This is the second wiggle match date from Loch Tay. The first comes from Oakbank Crannog and dates to around 500 BC. Previous palaeoenvironmental analysis at Oakbank and Milton Moreish had highlighted a number of similarities that later Crannogs in Loch Tay do not share. This includes the presence of cloudberry and some types of cereal. If we assume that the wiggle match date from Milton Morenish also dates the previous environmental analysis, we might suggest that in the period 500-350 BC at least some aspects of resource use and management changed little.
Moving forward we hope to be able to link this group of Oaks now dated from Milton Morenish to other timbers from across the loch.
We are now working towards further wiggle match dates and more dendrochronological results that will more precisely date the emergence and use of Crannogs across Loch Tay.
