Iron Age Hut Circles in the Middle of Nowhere: Submerged Prehistory in Upper Glen Cannich

by Roland Spencer-Jones

Does every excavation and discovery have a story behind it? Maybe. This one certainly does. When did the story start? With shepherds moving into empty land in the early 19^th century? With the gradual depopulation of Highland glens in the early half of the 20th century? With the construction of the largest dam in Scotland completed in 1952?

Maybe it’s best to start this story in early July 2021 with a walker and cyclist, Glenn Wilks, venturing into the remote west end of Loch Mullardoch. This large reservoir loch was created from two previous lochs, Lungard and Mullardoch, when a dam was built in upper Glen Cannich flooding the upper glen for a distance of 15km. The dry summer of 2021 produced unusually low water level in the loch, exposing kilometres of bare sand and gravel at its western end. The walker, Glenn, noticed that the now exposed reservoir bed contained several circular stone structures. Although he wasn’t an archaeologist, he recognised that these were special and so took photographs and videos as a record of what might soon be covered up by the water again.

Once he was out of the glen, he contacted Historic Environment Scotland with the information and photos. A serendipitous encounter between one of the HES officers and the author in Beauly soon after this, ended with the officer sharing the knowledge of this new find. Fortunately, the author had himself been to this area before, on a walking trip in 2014 when the water level in the reservoir was much higher. So, he knew the area and the difficulty of access, and yet was enthused at the prospect of investigating these features.

The NOSAS Crannogs Project – Update, December 2022

by Richard Guest

The Crannogs project has now been running for a couple of years.  Starting as a desktop exercise, we have now progressed to some site investigation and have managed a couple of dives.

A second phase of desktop study is underway and a picture of potential crannog occurrence in Wester Ross, Lochaber and Badenoch is beginning to emerge.  Wester Ross has been a real challenge to study, with literally thousands of lochs and lochans, liberally scattered with innumerable islands.  Many of these will be natural and picking out those which may be man made is no easy task.

Loch Achilty crannog (HER MHG7791, Canmore 12472) being easily accessible, had already been snorkelled and this verified that it was an artificial island, so it was chosen as the first proper dive.  Duncan Ross from the Nautical Archaeology Society joined me for two days diving in August and you can find his blog on the experience elsewhere on the website, so I will not go into too much detail.  Travelling in the good ship “Haggis” of the Blackburn line, (a tiny rowing boat ably skippered by Dave Coombs) escorted by the canoes of James McComas and Steve North, we made landfall on the crannog, donned our dive gear and plunged in.

Surveying Loch Achility, August 2022.

We were able to find several substantial timbers embedded in the silt at the base of the stone mound, at a depth of only about two metres.  What these are, is open to debate but some of them appear to go underneath the stones so are probably part of the original construction.  There is certainly the potential to take a small sample for carbon dating and the NOSAS committee will need to decide whether the project is to go in this direction, or whether we continue to just observe and survey.

My Highland Adventure: Diving Loch Achilty Crannog and HMS Natal

by Duncan Ross

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. The crannog centre at Loch Tay focuses on the iron age roundhouse model that was discovered there, but little proof exists that others were constructed and utilised in the same way. The depth of the Loch Achilty crannog, previously unrecorded, is an ultra-accessible 2.5 metres. Needless to say, dive times were extremely long for Richard and myself.

The NOSAS Crannogs Project

by Richard Guest

I have long been fascinated by crannogs. These are articial island dwellings such as the one in Loch Achilty, pictured above (see Canmore).  I remember back in the 80’s tiptoeing across a partly submerged causeway to visit one in a Shetland lochan.  Then, later, visiting the reconstruction in Loch Tay and seeing a TV programme about it.  Later still, whilst on a Nautical Archaeology Society training course I met one of the divers who had been on the Loch Tay project and heard first hand what it was like to make such amazing discoveries.

About 10 years ago, my late wife Jonie and I decided to try and walk out to the Redcastle crannog in the Beauly Firth (see Canmore).  About twenty squelchy steps was enough to convince us that this was a BAD IDEA and we retreated to solid land.  And oh! The smell!  So the next expedition was by boat at high tide and we passed over Phopachy crannog (see Canmore), which we could see on the sounder but could make nothing out through the water.  Another trip at a lower state of tide, we could see the crannog but the water around it was too shallow to approach in the boat.  We didn’t try again.

What we did do was to dive around another crannog, the one in Loch Brora (see Canmore).  The water was so peaty we saw literally nothing.  We knew we had reached the bottom when we felt it beneath us.  I put my hand in front of my mask but couldn’t see it, even with a powerful torch.  I think I could feel some square timber but it might have been a modern fence post caught in weed.

More recently I became aware, through both diving and archaeology sources, of discoveries of Neolithic pottery found underwater around crannogs in the western isles (see Current Archaeology article).  This exploded the received wisdom that crannogs were of iron age to post medieval date.  Then in 2021 NOSAS were lucky enough to have a “Zoom” lecture about crannogs, by Michael Stratigos from the University of York, which is available on You Tube (below). This is when the idea for a NOSAS crannogs project was born.

Kinellan Crannog, Strathpeffer

by John Wombell

Loch Kinellan, Google Earth 2015.

A few notes on Kinellan Crannog for crannog enthusiasts.  We are fortunate to live at Kinellan, about 400m away from the crannog as the crow flies.  In February this year Kinellan Loch froze over to a depth of 10” and we had days of glorious sunshine when local families were taking their lockdown exercise out on the ice, and we spent an afternoon on the crannog taking photos and  chatting to neighbours and their children. About 15 years ago I remember leading a NOSAS visit out to the island during another big freeze.

Some years ago 4 NOSAS members obtained permission from Historic Scotland and the owner to remove some fallen willow that had tumbled into the loch on the south side, in order that locals and visitors could see from the shore track the Medieval stone work surrounding most of the artificial island.  That was two days of very hard work, hand winching fallen trees back out of the loch then cutting them up.   Seeing young children exploring the island this February made me wonder whether the crannog was ever a family home with children playing or had it always been a male dominated stronghold.

Fraser’s 1916/17 report of the 1914/15 and 16 excavations was published in the PSAS and is available online. It is compulsive reading and I shall not spoil it for you by delving too far into the report.  Mr Fraser was a teacher in Dingwall and was only able to supervise the excavations part time and during school holidays.  With WW1 raging he had difficulty finding workmen but he eventually found two local men and all work appears to have been done with spades.  There is no mention of trowels.  He did however engage a Dingwall architect to make measured drawings and another teacher to make sketches.   A third person undertook the photography.  Fraser was as thorough as he could be at that time and he records a lot of detail.  I do not know whether there is an official archive stored away somewhere but a century on I think an updated expert re-interpretation of Fraser’s work would be a good starting point for new research.

The last known use of the crannog was as a kitchen garden and orchard by the tenant of Kinellan Home Farm in the late 19^th and early 20^th C.  A thicket of old fruit tree rootstock scrub still survives and few tangled gooseberry bushes.  Today though the crannog is dominated by dense mature ash and willow trees, an occasional gnarled Hawthorn and two very fine birch trees.  Many of the willows have fallen down, most are dead and rotting away but a good number, especially those that have tumbled into the loch remain alive and have produced masses of new stem growth called Phoenix growth – raised from the dead!

The Archaeology of the Findhorn Dunes

by Michael Sharpe

Findhorn Dunes Site from the NE. In the upper left is the caravan park, and beyond the Cromarty Sutors.

Introduction

This story begins back in 2002 or so, when during a conversation about local history and archaeology, a local farmer and digger driver I had worked with mentioned to me that he knew of a site in the dunes east of Findhorn Village, Moray, where people had found flint in the past (Figure 1). I decided to go and have a look, and before long was finding not only flint tools and debitage, but also pot sherds, beads, fragments of copper alloy, and the remains of a midden. It is likely that this is the site of a flint scatter and old land surface (OLS) reported by Ian Shepherd (1977) and recorded on the Moray Sites and Monuments Record (NJ06SE0010 – Findhorn), although there is a discrepancy of 0.5km as to location. He probably wouldn’t have had even a basic GPS unit at his disposal, and it’s difficult to accurately pinpoint locations among the dunes.

Fig. 1 Location map

What follows is summary of the results of 15 years of surface collecting of finds, and recent efforts to investigate the site more systematically: namely a few test pits in 2016, but mainly a weekend of work in 2017—an informal dig staffed mostly, if not entirely, by NOSAS members. Permission for the collecting and minimal digging was given early on by the Findhorn Dunes Trust, which has a duty of care for the land surrounding the site.

The local archaeological context

I won’t attempt an exhaustive summary of the archaeology of the area, as there are many good publications that do that, including numerous papers in the Proceedings of the Society of Antiquaries of Scotland. Suffice it to say that broadly, within the coastal lowlands of the south Moray Firth coast, there is ample evidence of prehistoric occupation from the Mesolithic onwards. This ranges from Mesolithic and Neolithic arrowheads at Culbin; numerous Bronze Age (BA) cist burials, such as those at Burgie Lodge Farm near Rafford, one of which contained a jet necklace (Callander 1916); and larger BA burial monuments, such as the Clava Cairns near Culloden. As at Rosemarkie, there are numerous caves on the coast between Hopeman and Lossiemouth where excavations—most recently by Ian Armit—have found evidence of occupation from the Mesolithic onwards, including BA burials, and the remains of decapitated individuals from the IA. Excavations by Fraser Hunter at Birnie—south of Elgin—and at Clarkly Hill near Burghead revealed IA farming settlements on the productive farmland of the coastal lowlands, and also evidence of probable contact with the Romans.

Findhorn and its immediate surroundings have offered up: a BA hoard containing two spear-heads and a socketed axe (Callander 1920); a rich BA burial from Findhorn Village in which a large cinerary urn contained the cremated remains of a young woman and a neonate as well as a substantial number of faience beads, a rare find in the UK (Shepherd and Shepherd 2001); and the remains of two cremated individuals among the dunes east of the village (Black 1891).

Bradley et al. (2016) have proposed the new site type of Maritime Havens: areas which developed early on after the Pleistocene Ice Age, and which went on to become centres of trade and industry, with extensive links across both water and land. The exceptional quantity of artefacts found at Culbin Sands during the 17th to 19th centuries led him to propose that the Culbin Sands was one such haven. Due to its proximity, the people using the Findhorn Dunes Site were likely connected with this activity. The one artefact type which connects this dunes site, the Findhorn burial, and Culbin Sands also happens to be one of the rarest—faience beads.

A Year of Highland Archaeology

by James McComas (NOSAS)

A Year of Highland Archaeology book cover, showing Tarradale Through Time excavation trench with the settings of a possible stone hut. The same trench yielded several rare antler tools.

NOSAS has just published A Year of Highland Archaeology: A Collection of the Projects and Activities of the North of Scotland Archaeological Society . This new book includes 10 articles which explore some of the diverse recent projects that we has been involved with. These range from large scale funded excavations through to group surveys and small scale research projects. They highlight Highland locations from the west to the east coast, from Speyside to Sutherland.

Projects featured include the lottery funded Tarradale Through Time Project, which in 2017 saw 6000 year old antler tools uncovered near Muir of Ord on the Black Isle.  These very rare finds included the remains of a harpoon point and two “T axes” left behind by hunter gatherers on the shores of the Beauly Firth. The T axes are two of only five examples so far known in the whole of Scotland. The trench where these were found also tantalisingly revealed the possible stone setting of a Mesolithic hut. Tarradale Through Time continues in Autumn 2019 with the excavation of potentially one of the largest barrow cemeteries in Scotland (further information at www.tarradalethroughtime.co.uk).

Another chapter focuses on Torvean Hillfort, a neglected structure on the edge of Inverness. Torvean was perhaps constructed more than 2000 years ago, but it is today sadly under threat from persistent trail bike damage. A different chapter tells the much more positive story of how a collection of 400 historic maps relating to the Lovat Highland Estates, covering extensive areas west of Inverness, have now been scanned and made available online.

A different chapter still focuses on the NOSAS’s work with Scotland’s Rock Art Project. ScRAP aims to log as many as possible of the mysterious carved “cup marks” which appear on Scotland’s boulders and rock faces over a 5 year project. The precise date of these carvings, of which there are many good examples in the Highlands, is unknown but they are thought to have been mainly created in the Neolithic period around 6,000 to 4,000 years ago. Other archaeological locations explored in the book include Ormond Castle in Avoch, a prehistoric roundhouse landscape in Glen Urquhart, and Gruinard Island in Wester Ross.

Initiating CAERoS: Coastal Archaeology and Erosion in Wester Ross

by Stephanie Piper, Newcastle University (stephanie.piper@newcastle.ac.uk)

In April 2019 myself, two Master’s students from Newcastle University – Callum Hardman and Holly Holmes, and Paco Martínez-Sevilla, a colleague from Durham University, based ourselves in Poolewe to begin a week-long walk-over survey of the coastline around Loch Ewe. The aims of the survey were to:

1. Establish the potential of eroding coastlines to yield early prehistoric sites in the north-west Highlands.
2. Contribute to active monitoring of archaeological sites at risk of erosion.

Why were we drawn to this remote part of the Scottish Highlands? Precisely because it is remote! The evidence for early prehistoric occupation is sparse across much of the Highland region. For example, there is no evidence for Mesolithic occupation along the coast between Redpoint, in Gairloch parish, and Smoo Cave, Durness parish (although this has not been fully confirmed). By contrast, the coasts around the Inner Sound of Skye and Applecross were intensively surveyed by the Scotland’s First Settlers project from 1998. The project identified over 130 new archaeological sites, including the Mesolithic rockshelter site at Sand, Applecross. We felt sure that the absence of sites to the north was due to a lack of research, primarily because of the remoteness of the region and lack of ‘visible’ archaeology, rather than an absence of people in the past. CAERoS was therefore initiated to investigate the next stretch of coastline, north of where Scotland’s First Settlers had finished and with the hope of finding further evidence for Mesolithic coastal occupation.

As this was just the start, our methodology was simple: walk, and look. I spent several years during my postgraduate degrees working on a project in the Western Isles with Durham University. During the field seasons, we identified a number of Mesolithic sites exposed by coastal erosion (two on Harris, and three around the Bhaltos peninsula in Lewis). Because early prehistoric sites are often deeply buried under peat or machair, they are invisible to traditional means of initial identification such as a field-walking, and are so ephemeral they rarely respond to geophysics. The destruction caused by erosive processes therefore provides opportunities to investigate hidden archaeology, including early buried landscapes. This then, was to be our ‘window’ to the past, and we struck out across the headlands to observe and record any archaeology within c.50m of the coastline using the ShoreUpdate App, developed by the Scotland’s Coastal Heritage at Risk project (SCHARP).

Fig.1 Exploring the circular stone structures and raised beach deposits at An Sean Inbhir

On the first day, we walked west, covering the stretch from Cove Battery to Camas Mor. We noted several sites along the way, including circular stone structures and modern fisherman’s bothies at An Sean Inbhir (Fig.1), a turf-covered wall at NG763921, which is probably associated with the abandoned township and head dyke at Camustrolvaig, and a sheepfold built against a rocky outcrop at NG805925. The building recorded at Camas A’Chall wasn’t identified, nor does it appear on the current OS map. By far the most interesting aspect of this stretch was the World War II memorial and three abandoned lifeboats (centred on the memorial at NG796926, Fig. 2). The memorial is in commemoration of those who lost their lives after the American Liberty Ship USS William H. Welch ran aground at Foura Island, on 26th February 1944. The plaque is also dedicated to local community members who were involved in the rescue efforts. The plaque does not appear in the HER and the abandoned lifeboats are at serious risk, situated in the intertidal zone. These have been logged with SCHARP who are very interested in incorporating them into a future project. If anyone happens to be in the area and visit them, it would be worthwhile continuing to take photographs of their condition.

Tarradale Through Time: 2018 Excavations

by Eric Grant

In September 2018 two sites were investigated by TARRADALE THROUGH TIME near Muir of Ord. These were a fortified enclosure just west of Gilchrist church and a rather enigmatic and possibly ritual site south of Gilchrist church, but located on Balvattie Farm.

Gilchrist Promontory Fort

The Gilchrist fort is a rather unusual monument  and walking past it gives no clue to its existence, size or age. Canmore describes it as a promontory fort based on their interpretation of crop marks as the arcs of three concentric ditches “Apparently designed to cut off approach to a tongue of low-lying and comparatively level ground running NW into marshland, they are in effect part of the defensive system of a promontory fort measuring about 85 m by 30 m”.

In addition to the black-and-white photographs on the Canmore database, the late Jim bone, who was an enthusiastic archaeologist and also a pilot, took some good colour photographs of the site. Jim’s aerial photograph shows three dark green curved features representing the fort’s ditches on the east side of the promontory. The ditches are now under cultivation and have been filled in and ploughed flat so there is nothing to see above ground; it is only the aerial photographs that have encouraged archaeologists to see this as a fortified promontory. It is unusual to find a promontory fort inland unless it is in a situation like this where it is surrounded by water or marshland. Most hill and promontory forts in Scotland appear to have been constructed during the late Bronze Age and Iron Age and the latest ones were built or reoccupied in Pictish times.

Our research agenda sought to identify and characterise the ditches, and to ascertain when the fort was constructed, how long it was occupied and what activities may have taken place there. Three large trenches were initially opened, one running at right angles across the defensive ditches, a second running from the long side of the fort down into the bog and a third on the highest part of the interior of the fort. We were very quickly able to establish that the three ditches seen on aerial photographs did exist, with a hint of a fourth ditch closer into the fort. The outermost ditch was reasonably shallow but the second ditch was a massive construction 5-6 m wide at the top and sloping steeply to about 1.5 m below the plough soil though we consider that the upper part of the ditches have been lost due to ploughing and the intervening banks of excavated material flattened. The third innermost ditch was not quite so deep, but right on the edge of the actual fort area we found what may be an inner ditch that might have continued round the fort perimeter as a wall and perhaps with a timber fence palisade on top or just in front.

Experimental Archaeology: Learning about Technologies in the Past

by Susan Kruse (ARCH and NOSAS)

Thanks to funding from Historic Environment Scotland and the Heritage Lottery Fund, ARCH launched an exciting project ‘Experimental Archaeology: Learning about Technologies in the Past’ in October 2017. The project had three main strands. In the first year, 13 experimental archaeology days and 10 school visits took place where craftspeople demonstrated and explained different technologies used in the past. The workshops were filmed and the edited videos and blogs for each workshop can be accessed on the ARCH website.

In the second year, the objects resulting from these workshops will then be used to create loans boxes which will be freely available to borrow. Our workshop leaders often generously provided more than one object. An archaeologist and teacher will now work together to create learning materials, so that the loans box and videos of the experimental sessions can be used in schools and other groups. The project already has attracted a wide and diverse audience, and we hope that the loans boxes will also contribute to this legacy.

The idea for the project emerged from North Kessock & District Local History Society’s Feats of Clay project, where ARCH helped facilitate a visit by Neil Burridge who demonstrated Bronze Age metalworking. Everyone in the audience was caught up in the excitement of the day, and learned so much about how objects were made, what raw materials were needed, and how craftsmen in the past managed without gauges and modern equipment.

In the first year 13 workshops took place, one a month, each showcasing a skill from the past, spanning from earliest settlers to more recent times. The workshops were exciting to attend, but were also filmed.
