During lockdown, apart from eating too many pancakes, NASAC (Nautical Archaeology Society affiliated diving club) member Duncan Ross set himself a grand future task of visiting different kinds of underwater archaeological sites around Britain. This summer he managed to add a couple of unique Scottish sites to his gradually-expanding list.
After around two years of communication, in August 2022 I was invited to help out on a crannog investigation in the fairly anonymous Loch Achilty, just a little north of Inverness city. Assisting North of Scotland Archaeology Society (NOSAS) member Richard Guest and his intrepid team, I spent two days at a most-tranquil setting scuba diving, investigating, recording and taking photos and film of a site that could be anything from a couple of hundred years to a couple of thousand years old.
Crannogs are a fairly unchartered area in the field of archaeology, and most questions about their creation and the purpose of their locations within lochs remain unanswered and open to speculation. All that usually remains is an artificial island of stones piled on top of one another – artefacts and human traces are frustratingly rare, as are diagnostic patterns that could lead to a method of classification.
