Droning on about Tarradale

Back in 2017, I caved in to the demands of consumerism, and purchased a new quadcopter, a Phantom 3 Advanced, which is equipped with a camera and GPS unit. I flew multiple flights around Avoch but, after a while, the novelty of seeing one’s house from the air at different angles and altitudes begins to wear thin, and I began to wonder what I could actually do with a drone. Having always had an interest in archaeology and, spurred on by seeing some of the images Alan Thompson of NOSAS had created, I decided to carry out a few experiments of my own.

My first flights took in locations such as the distillery and settlement at Mulchaich, and the features of Kinbeachie castle – sites which had already been mapped by Alan by drone, the results of which I could use as a ‘benchmark’ against which I could compare those of my own.

At the same time, I began experimenting with various flight planning apps which allow for off-line autonomous flight planning, as well as online platforms for image processing. I found that “DroneDeploy” and “Mapsmadeasy” combined provided a fairly user-friendly pipeline, whereby image capture and photogrammetry can produce georeferenced photomosaics and digital surface models (DSMs). These can then be imported into software such as QGIS for further processing.

Having found the software which satisfied my needs, I then turned my attention to potential sites which I could map – and decided on the cropmarks of the Barrow Cemetery at Tarradale. At this point, my intent was purely to satisfy my own curiosity – just to see what I could see, and how it would compare with the archaeology found at the forthcoming 2019 dig.

And so, on 10 June 2018, accompanied by my daughter Emma to act as co-pilot and “spotter”, I visisted Tarradale to map the area with the drone. I can still recall the excitement I felt as the images began to appear on the monitor of the remote controller, which showed the cropmarks were developing. However, my satisfaction was tempered somewhat when I got home and began to process the photographs. Although the cropmarks were indeed evolving, the crop was insufficiently ripe, and many of the details remained hidden (see image below).

Digging the Pictish Fort at Burghead

by Anji Hancock (NOSAS)

My childhood was spent in Lossiemouth, a mere 8 miles from Burghead. Then, my knowledge of Burghead was a jumbled mix of Druidism, a Roman Well, the burning of the Clavie and the harbour my father’s fishing boat used when the wind was in the wrong direction to get into Lossiemouth harbour. As a child I felt it was definitely a place of history and mystery, but I can’t remember any real historical importance being given to it – well not in Lossiemouth circles anyway! Roll on half a century and Dr. Gordon Noble’s Northern Picts Project and Burghead has become the focus of some recent excavations.

The original fort occupied over 7 acres but, sadly, much of this was destroyed with the building of the town and the re-building of the harbour in the early 19th century. The remaining area of the fort, with the exception of the Coastguard houses and their gardens are scheduled. This means that an excavation in the Coastguard house gardens could be undertaken with only the permission of the owners. Unfortunately, I was unable to take part in these earlier digs when some interesting occupation layers and a coin from the reign of Alfred the Great were uncovered.

However, the word went out on the Northern Picts Facebook page that Gordon and his team from Aberdeen University were returning to dig again. This time permission from Historic Environment Scotland had been received to dig a specified number of test pits and two explorations into the fort wall. Fortunately, Paul and I were able to join the dig for 3 days.

What remains of Burghead fort is sited on 2 levels- the upper and lower enclosures. The upper enclosure is believed to have been for the hierarchy of the community and the lower level for the habitation of the lower classes.

As befitting our lowly status we spent 2 days cleaning, trowelling, deturfing, shovelling and mattocking in the test pits on the lower level. Only one test pit revealed anything of interest in the way of structure. The others bottomed out with a layer of stones. Initially, there were high hopes this might be a deliberate layer of cobbles, but realistically, it was decided that so close to the sea, and with the history of coastal change that has happened in this area, it was more likely to be a natural layer. A visit from a couple of people with geology knowledge confirmed this.

One inner wall exploration was on this lower level and the other on the upper level. Cathy MacIver from AOC was contracted to work on the lower level wall. For days she seemed to be moving large rocks and images of my time at Clachtoll came back to me! As she went further into the debris which had been piled up against the lower-fort rampart great care had to be taken to keep the area stable and safe. Her toil was rewarded with a layer of black claggy mud which was believed to be contempory with the occupation of the fort.
