Troding carefully

Nick Mason – Archaeology Officer

Welcome to the first MOTM blog, a regular feature we will be publishing in conjunction with the Monuments for the Future project. Each month we’ll take a look at a type of Scheduled Monument that we have in the Park: we’ll let you know how to spot monuments when out and about, what different monuments tell us about the people who once lived and worked here, and why these monuments are protected.

This month it’s the Kirby Bank Trod, SM1405913. My computer has immediately told me I have made a spelling error, and if you’re not familiar with the local dialects or the Moors you might not have come across the word before either. ‘Trod’ is a term for a trackway laid with flagstones, and there is a network of historic examples criss-crossing the North York Moors. There are other ancient flagged paths around the UK, but this National Park has the most known surviving trods in one place, and they are seen as characteristic of the area. Sometimes they follow the same routes as ‘Pannierways’, long routes traversed by trains of pack horses loaded with goods. A ‘Pannierman’ was a person who transported fish from ports to inland fishmongers, a primary use of some trods.

A trod is a deceptively simple construction. Flagstones, sometimes carved, sometimes rough, are laid end to end in single file between two points. They are frequently made of stone from nearby quarries, and are usually no more than 0.5 metres (20 inches) wide. Surviving examples today often have a wide concave groove worn along the centre of the path, indicating how much traffic they have supported over the years.

We think the earliest examples were probably built by the local monastic communities, who would likely be the only organisations with the resources to lay them in the medieval period. Trods would have been efficient ways of transporting goods (especially wool) between the many abbeys and priories and granges (outlying properties). As their usefulness became apparent, more and more were laid, linking market towns, villages and farms across the moors.

Further trods were built in the 18th century, and there may have been a bit of a renaissance due to smuggling enterprises on the coast. Although they slowly declined as better road surface technologies appeared which were then followed by railways, as late as 1890 pack horses could still be seen filing through Rosedale.

We hold about 220 records for trods: many of these are fragments, just a few flags left in place, but others can still be seen stretching for miles across the landscape.

'Quaker's Causeway' on High Moor, damaged by vehicles crossing - copyright NYMNPAOne 400 metre (1/4 mile) section of trod has been designated as a Scheduled Monument, protecting it as an archaeological feature of national significance. This is thanks to the continued efforts of the Kirby, Great Broughton and Ingleby Greenhow Local History Group – Grant Frew and Jackie Cove-Smith from the Group explain the Kirby Bank Trod’s special significance:

Paved causeways are a familiar feature on our Moors, yet surviving ones in good condition are becoming increasingly rare. It has been estimated that around 80% of our trods known in the 19th Century have now gone. With this in mind, ten years ago our local history group ‘adopted’ one – the Kirby Bank Trod.

Trods are notoriously difficult to date, but we know this one was constructed on a man-made embankment in the late 12th or early 13th Century for the Cistercian monks at Rievaulx to link their monastery with their granges, their fisheries and their salt pans on the Tees. Centuries later it was used to transport building stone down from the quarries on the Bank: later still alum for the dyeing industry, jet for jewellery, and today by local and long-distance walkers.

We’ve worked really hard to maintain a high profile for the Trod: holding a Festival of British Archaeology event, producing a Heritage Trail leaflet, publishing articles in the Dalesman, the Voice of the Moors and the local press. On the ground we’ve also germinated and planted replacement hawthorn ‘waymarkers’, arranged geophysical surveys and organised guided walks.

We also carry our spades, edgers and brooms up the Bank twice a year to help keep the Trod from disappearing under grass and gorse!

As a Green Road, Kirby Bank and its Trod suffered from frequent use by trail bikes and 4×4 leisure vehicles, causing serious damage to the stones and sandstone waymarkers and degrading the embankment the causeway rests on. We needed legal protection.

In 2012 Historic England granted Scheduled Monument status to the Trod, in large part because of the man-made embankment (there’s no other parallel in England) and its historical context. Even with this significant status, vehicle abuse continued. Finally this November, after years of lobbying by our history group and by Kirkby Parish Council and with the support of the MP, district and county councillors and a variety of interested organisations (including the National Park Historic Environment staff), the County published a Traffic Regulation Order prohibiting motorised leisure vehicle access.  All is not yet over! Any objectors have until just before Christmas to file for a judicial review of the Order in the High Court. We can but just wait and see!’

Luckily the Kirby Bank Trod is in good hands, allowing locals and visitors to continue engaging with the past by walking in the footsteps of Cistercian monks. But as the Group states, about 80% of known trods have already been lost. Given their location on obvious routes linking settlements, they can often come under threat from modern roadworks. They also represented a very handy source of stone for builders over the past few centuries. The few remaining sections need to be taken care of to ensure our local cultural character and heritage is maintained.

As ever, you can find out more about the fascinating archaeology of the North York Moors using our interactive Historic Environment Record map – you could look up your nearest trod and go and have a look. We’re always keen to hear what you find, so don’t hesitate to get in touch if you think a trod needs some attention.

What do you think?

As part of the new 25 year Environment Plan, the Department of the Environment, Farming and Rural Affairs launched a review back in May looking at the roles of National Parks and Areas of Outstanding Natural Beauty (AONB). National Parks and AONBs are the two main landscape protections in England. The idea behind the review is to make sure our protected landscapes are fit for purpose going forward.


As part of this review Defra have issued a call for evidence. In particular they want to hear from interested people who live in, work in, visit protected landscape, and/or care about our landscapes, biodiversity and heritage: what do you think?

 

Defra need views and ideas on National Park and AONBs’ roles in conserving nature and biodiversity, enhancing wildlife and supporting the recovering of our natural habitats, shaping landscape and beauty, protecting cultural heritage, working with farmers and land managers, supporting and managing access and recreation, encouraging volunteering and improving health and wellbeing for everyone.

 

There are also questions about how National Park and AONBs are governed, funded and designated; how different national designations work together; how well National Parks and AONBs work collectively with other organisations and with the public; and how National Parks and AONBs support the local communities who live and work within their areas.

 

Submissions will be considered alongside the evidence being gathered by Julian Glover and his team who are leading on the review. If you want to add your thoughts please note that the public call for evidence closes on 18 December, the final report and recommendations are expected by autumn 2019.

 

It’s an opportunity to make changes for the good.

We are Family

Alasdair Fagan – Woodland Creation Officer

All 15 UK National Parks are unique with their own landscape character, natural assets and cultural heritage. But we have a lot in common too, and therefore there is much value in sharing issues, experiences and lessons, and keeping in touch with each National Park that makes up our National Park Family.

The Tree and Woodlands Officer Group (TWOG) focuses on all things woodland and tree related across the UK National Parks. Every National Park’s Tree and/or Woodland Officers are members of TWOG and each year a particular Park hosts an annual gathering so members can get together in person to talk through issues and see what’s happening on the ground beyond their own Park.

2018 was our turn to host the TWOG meeting, so back in October Tree and/or Woodland Officers from other National Parks arrived in Helmsley.

DAY ONE

We started with a welcome meeting and an introduction to the North York Moors by Andy Wilson, our Chief Executive.

We then headed out to Bilsdale stopping at key vantage points to look over woodland creation projects past, present and future throughout this linear north/south dale. There was a discussion around each National Park’s approach to tree planting and about the finer details of woodland creation such as landscaping, appropriate locations and grant support. For the North York Moors woodland creation is a priority and we have resources available to work with landowners to facilitate this. We’ve started with smallish individual sites but are starting to develop a more targeted strategic approach for the future.

We then headed up into Tripsdale Site of Special Scientific Interest (SSSI) which is valued for a mix of habitats. Within the area is High Wood which includes as many as 300 ancient and veteran trees. We considered the management of the Ancient Semi Natural Woodland area as a whole and also the invaluable irreplaceable individual trees. High Wood is a wood pasture – a grazed woodland – but currently the sheep are fenced out as we’re establishing young trees to help maintain succession on the site.

That first evening we had a talk by Professor Ian Rotherham from Sheffield Hallam University on ‘Shadow Woodlands’ and the significance of scrub. Shadow woodlands are essentially areas that still have remnant trees and woodland flora but are no longer woodland as such – they could provide appropriate place to target for woodland re-creation in the future.

DAY TWO

The next day we headed off to the Forestry Commission’s Cropton Forest to have a look at their natural flood management features on Sutherland Beck. These features, such as woody debris dams where installed as part of the ‘Slowing the Flow’ project aimed at abating  past flooding issues in the town of Pickering downstream.

We then travelled north and after a quick stop at the Hole of Horcum on Levisham Estate to discuss past tree planting for landscape and natural flood management reasons, we stopped in Glaisdale.

We went into the West Arncliff 44 hectare woodland site to look at the work that began 6 years ago to convert part of the woodland from conifer plantation back to native broadleaved woodland. This site demonstrates the long term commitment required to achieve PAWS restoration. It’s part of a wider site that includes SSSI and Special Area of Conservation (SAC). We also got to see the nationally scarce Killarney Fern (Trichomanes speciosum).

This visit inspired debates, discussions and recommendations around the challenges of restoring ancient woodland in hard to access sites.

The last stop of the day was at a vantage point above Fryup Dale. This site provided the opportunity to discuss wood creation (again), work to integrate historic commercial forestry into the landscape and other woodland issues on a landscape scale. Sharing perspectives and comparisons from different National Parks was very illuminating.

That evening we listened to another two fascinating talks from invited speakers. Nationally renowned woodland expert George Peterkin presented on Lady Park Wood, a woodland local to him in the Wye Valley, examining the context of a woodland not managed for 15-years and lessons that can be learnt. Brian Walker, who worked for the Forestry Commission for over 40 years, presented on the interconnected biodiversity of the Forestry Commission’s Langdale Forest.

DAY THREE

On the morning after we closed with a formal meeting considering national issues such as Brexit implications for grant funding and payments for public goods, as well as woodland management and woodland creation (yet again). Then everyone went back to their home National Parks.

TWOG is just one way in which the National Park Family works and communicates with each other. I am glad it all worked out, even the weather was good and the autumn colours looked fabulous. I am very grateful to have had the opportunity to host such dedicated and experienced woodland representatives here in the North York Moors. I’m already looking forward to the next TWOG meeting, in 2019 at Snowdonia National Park.

Sowing the Seeds of Recovery

Richard Baines – Turtle Dove Project Officer

There are few more rewarding things in life than creating new habitat for wildlife and then watching with delight as birds and other animals move in.

What would make it extra special would be hearing a Turtle Dove sing its beautiful purring song.

Turtle dove courtship at Sutton Bank NYMNP Visitor Centre May 2015 by Richard Bennet, North Yorkshire Turtle Dove Project

A major part of our HLF funded North Yorkshire Turtle Dove Project involves working with land managers to create exactly the right feeding opportunities for Turtle Doves. The National Park and the Project have a brand new grant aimed at providing flower rich plots from which Turtle Doves can feed on a natural seed source.

We are really pleased that this autumn 11 farm businesses have established 17 Turtle Dove flower plots covering a total of five hectares within our project area. This is a great start and it’s very exciting that so many land managers are keen to help; however we need many more if we are going to have a chance of making a difference.

The pioneering 11 includes a wide range of landowners and tenants such as our first community Turtle Dove reserve in Sawdon village sown by the local community and primary school, Ampleforth Plus Social Enterprise, the Danby Moors Farming and Wykeham Farm businesses, and Hanson Quarry near Wykeham.

The sown plots are needed because many of the wild flowers that provide seed such as Common Fumitory and Birds-foot Trefoil are no longer common in the arable landscape which is one of the major reasons Turtle Doves are now at risk of extinction. The plots will also support a range of other scarce arable plants such as the locally rare Shepherd’s Needle. We are working with the local Cornfield Flowers Project – Into the Community to make sure we provide available ground for many naturally occurring but declining local flowers.

These new plots will not only provide habitat for Turtle Doves they will also provide valuable for a whole range of declining farmland birds. Grey Partridge feed their chicks on invertebrates and need open fallow land rich in small insects. Our flower plots are sown at a very light sowing rate to leave a good proportion of the plot shallow which allows access for Partridge and other birds such as Yellowhammers searching for insects in the summer.

If you have arable or temporary grassland on your farm and you would like to help Turtle Doves please get in touch to find out more about the grant and payments on offer. Contact us or call the National Park’s Conservation Department 01439 772700.

Sworn defenders of the Historic Environment

Nick Mason – Archaeology Officer

You might have seem our recent post on the beginning of our new Monuments for the Future project, caring for the Scheduled Monuments in the North York Moors. Over the nine previous years of the Historic England funded Monument Management Scheme we were able to reduce the ‘At  Risk’ status of 212 of our monuments. We are wanting to build on that success and move forward with Monuments for the Future which is being supported by another generous grant from Historic England.

Since July this year we’ve already had a fantastic response from our dedicated Historic Environment volunteers. With volunteers and staff working together, we’re confident that over the next few years we can monitor and maintain the 842 Scheduled Monuments that we have within our boundary, and continue to reduce their ‘At Risk’ statuses, or else remove them from the Heritage at Risk Register altogether.

From coastal industrial sites threatened by erosion and climate change, to grand prehistoric earthworks under attack by flora and fauna, there is a huge range of archaeology at risk. Our scheduled sites represent almost the whole of the human story in Britain, and the list is ever growing with a possible monastic grange site currently being considered for designation. We’re working to protect our historic assets and to tell everyone we can about our wonderful heritage.

Over the coming months, we’ll be posting themed blogs focusing on the types of monuments found in the North York Moors, the reasons they are considered nationally important, and why some are currently in trouble.

This month we thought we should start by introducing some of the National Park Authority’s Historic Environment staff and get them to explain themselves in their own words.

Mags Waughman, Head of Historic Environment
After nearly twelve years working for the Authority, first as Archaeological Conservation Officer and later as the Monument Management Scheme Officer, I was very pleased to become Head of Historic Environment at the beginning of the summer. This is an exciting time for the National Park’s Historic Environment work – with new funding to support our work with Scheduled Monuments, new archaeological staff and a new Building Conservation team we are in a very good position to develop our work and look for new directions and projects.

Emma and Jo focus on Monuments for the Future and Nick and I will be working with them on the project, as well as looking after the Park’s undesignated heritage. Suzanne Lilley works with Maria as a second Building Conservation Officer and one day a week they are joined by Clair Shields who has worked in the Building Conservation team for a number of years. Part of my role is to liaise with Maria, Suzanne and Clair to make sure the whole historic environment is cared for equally. I also liaise with the Land of Iron team where Maria has a second role as Cultural Heritage Officer, assisted by Kim Devereux-West. Behind the scenes, one day each week the team still has the benefit of the many years of experience of Graham Lee, a previous Senior Archaeological Conservation Officer. I’m really looking forward to working with the new teams, seeing our plans take shape and watching the different projects make new discoveries or have a positive effect on our fantastic cultural heritage.

Emma Trevarthen, Monuments for the Future Project Officer
I’m an archaeologist with a background in aerial survey and Historic Environment Record (HER) management. My role with the National Park is to look at the threats and vulnerabilities of some of the Scheduled Monuments which have been on the Heritage at Risk Register for some time, and to try to find ways to improve their condition and sustain those improvements in the long term. I’ve already had a really good, positive response from landowners and I look forward to seeing more monuments in the North York Moors removed from the ‘At Risk’ Register over the next three years.

Jo Collins, Monuments for the Future Volunteers and Community Officer
My role is Volunteers and Community Officer for Monuments for the Future. I coordinate a group of volunteers who survey the condition of Scheduled Monuments, monitor walkers’ cairns on Scheduled Monuments and carry out practical conservation tasks. In the near future I’ll also be focussing on helping community groups to care for their local heritage. I’m looking forward to seeing the difference volunteers and community groups can make as Monuments for the Future progresses.

Maria-Elena Calderon, Building Conservation and Land of Iron Cultural Heritage Officer
I have worked in in archaeology for almost ten years, specifically in Built Heritage since 2013 when I was awarded a training bursary by the Chartered Institute for Archaeologists hosted by ASWYAS in Leeds. My work has taken me as far afield as Qatar but the majority has been spent in the UK from Orkney to Pontypridd and Cambridge. I have worked for the National Park for nearly two years and I relish the opportunity it provides me to help protect, improve and impart knowledge of the historic environment to residents, tourists and fellow National Park staff. I work as a Building Conservation Officer which involves assessing Listed Building and Conservation Area consent applications. I am fairly new to this role but I enjoy it immensely and receive great support from my fellow officers. We work with homeowners, planners and developers to insure that any development is conducted in a manner that is sympathetic to the heritage assets. As an Authority we also offer grants for the above where the development will result in an enhancement which our team administers. In addition to that we regularly offer advice in regard to traditional buildings either subject to planning proposals or other project based work within the National Park. We also work with volunteers undertaking surveys of listed building as part of the nationwide ‘Buildings at Risk’ scheme.

Nick Mason, Archaeology Officer
I’ve only been with the National Park now for 3 months, but what a time it’s been so far. I have been lucky enough to be an archaeologist all my professional life, but having responsibility for the sheer breadth of archaeology in one place is a new, and very exciting, experience. My role as archaeology officer means that I am interested in protecting all the heritage assets of the North York Moors, including unscheduled archaeology, ancient plough marks, and even possible structures marked on old OS maps. Sometimes development means that these must be affected, and we find ways to mitigate the effect, learning as much as we can as we go. Scheduled Monuments often represent a massive potential for undiscovered archaeology, and their setting in the landscape, the possible finds within, and the stories they can tell mean it’s worth doing all we can to look after them for the future.

If you’d like to be out and about more in the North York Moors and might be interested in volunteering opportunities at the same time, we’d love to hear from you. There are a range of tasks which need doing, from carrying out surveys and reporting on monuments to clearing patches of damaging bracken on wild moorlands.

Similarly, if you think you know of some material heritage currently under threat please don’t hesitate to get in touch, so we can see what can be done.

It’s dirty work but someone’s got to do it or: When all’s said and dung, don’t poo-poo the Dung Beetles

Sam Newton – Natural Heritage Trainee, Land of Iron

A single cow can produce over nine tonnes of dung per year, so across all domestic and wild herbivores imagine how this would quickly build up to mountainous proportions.

Fortunately there are many invertebrates whose life cycles involve clearing this up. Take Dung beetles – in the UK their annual role in the ecosystem is valued at £367 million, for cattle dung alone.

How the different groups of British Dung beetles utilise dung in different ways. Copyright Dung Beetle UK Mapping Project.

Dung  beetles are a collection of around 60 species in the UK, within the Scarabaeidae family which also includes non-dung feeding Chafers and Stag Beetles). The actual dung feeders are split into the Aphodiinae (dwellers, residing within dung) and the Geotrupidae and Onthophagus (tunnellers, burying beneath dung). Contrary to popular belief there a no dung rollers in the UK, as this group are only found in the tropics and sub-tropics. The adults of all groups feed on liquid within dung, while the larvae eat the solids.

These 60 species utilise dung differently and so avoid competition – they use dung from different animals, they feed at different times of day or year, they live in different habitats and they favour dung of assorted ages. The fact that all the species vary in their ecology enhances the benefits provided in dung recycling to the wider ecosystem, helping fertilise the soil and enhance soil structure, and reducing greenhouse gas emissions.

In addition, dung beetles transport mites between dung piles, which feed on fly and worm eggs, thus indirectly helping reduce fly numbers along with some gastrointestinal parasites that can affect livestock.

Dung beetles also provide an important food source to many animals, for example Aphodius prodromus (a small Aphodiinae dung dweller), which is incredibly numerous in early spring when there are few other invertebrates available.

So Dung beetles are incredibly useful, as well as being beautiful (without mites) and valuable in their own right.

However, all is not well in the dung beetle world. A 2016 review found over 25% of UK species were ‘Nationally Rare’ (found in 15 or less 10×10km squares across the UK) and four may already be extinct.

Changing farming practises and the disappearance of livestock from historic pastures is a major cause of this decline in the UK. The loss of dung structure produced by modern livestock breeds fed high protein diets is also detrimental, as dung beetles essentially end up drowning in the dung. Soil disturbance is damaging to some species, and wormer overuse (e.g. Ivermectin can indirectly reduce larval development and survival) is perhaps the main cause of decline, ironically destroying the role dung beetles played in reducing parasitic worms naturally.

So how can people make changes to help conserve Dung beetles and their role in day to day biodiversity? If you keep any livestock, use faecal egg counts to reduce worming, consider keeping a few hardy livestock out during the winter if your land is suitable, also not removing all the dung from out of horse paddocks enables a constant supply of high quality dung. If you don’t keep livestock, try and support the keeping of native breeds which have better quality dung for a Dung beetle’s needs.

The Ancient Egyptians associated Khepri, god of the rising sun, with a dung beetle (a Scarab) which every day was believed to move the sun across the sky. While I’m not suggesting worshipping Dung beetles per se, we can try and appreciate these beetles, understand their predicament and even try and help.

There is a Dung Beetle UK Mapping Project. For lots of help with identifying between species, and to be able to record sightings and help build up a picture of distribution – see their website.

Apologies for the titular puns.

Making Pictures

Nicola White – Land of Iron Film Maker Intern

I’ve spent the past 12 weeks clambering over the North York Moors with my camera, capturing the elements that form the Land of Iron Landscape Partnership Scheme. This adventure has been challenging, hilarious and hot (given the summer we’ve had).

I began with the Combs Wood excavation, bugging the volunteers each morning by crouching on the ground to get the best shot as they dodged their wheelbarrows around me. It was incredible to see them constantly uncovering something new and seeing just how much had been hidden by the nature that surrounded us. See Combs Wood Part 1 – Volunteering, Combs Wood Part 2, and Combs Wood Part 3.

I also got involved with the Warren Moor Mine conservation work this summer. The details of the huge chimney still on site really are incredible. My video focuses on the lime mortar work that the team have completed on the engine beds, as well as all the previous clearing that has taken place during the project in order to preserve the features. It’s impressive to view the impact that Land of Iron has had on this area, and for that reason it’s recorded in my video. See Warren Moor – The Movie

I didn’t just concentrate on the impressive industrial building sights; I’ve also created a video showing the environmental conservation work undergone. From fences and walk ways at Fen Bog to forest work and tree planting across Rosedale, my video illustrates how this work is restoring habitats and encouraging rare species. See what I saw

The final video of my creation sets out to capture the entire essence of the Land of Iron. Focusing on the three main aspects – history, people, environment – this video uses interviews with the core team and footage that I’ve recorded throughout my summer with them, to explain what the programme is all about. See the whole picture …

This summer has been an incredible opportunity to learn and create. The people surrounding and supporting the Land of Iron scheme should receive a medal for all the work they do; constantly typing away on their keyboards in the office or covered in mud down a one-meter deep hole. It’s been a pleasure to dig in the mud with them for such a short time, and I hope I spend all my future summers in a similar way.

Something else … The Land of Iron Landscape Partnership Scheme is approaching its halfway point with building conservation works starting on site and teams of volunteers across the North York Moors helping us care for our fascinating industrial heritage. We’re currently undertaking an EVALUATION SURVEY – this is a really important way to check the scheme is heading in the right direction and achieving what it wants to. Please give us a few minutes of your time to tell us what you think. Your feedback will help shape the next stage of the programme. 

Warren Moor Mine: Part Two – the excavation

Eleanor Lees – Land of Iron Community Archaeology Intern

We were back at Warren Moor Mine within weeks of completing the lime mortaring of the winding engine bed, but this time to carry out an archaeological excavation. Five Land of Iron volunteers and two members of staff investigated two trenches dug across the ditch on the site. One trench was between the winding engine bed and the downcast shaft, and the other further upstream, close to the boiler house and chimney. The purpose of the excavation was to build upon the information left to us by those who built and operated the mine site, and the knowledge gained by John Owen and his team from their 1970s investigations.

A very short history recap

Warren Moor Mine was only in use for a grand total of nine years, on and off, between 1857 and 1874. The land was first mined by a John Watson from 1865 to 1868 as part of the Warren Moor Mine Company Ltd. After being taken back by the Kildale Estate (land owners), in 1872 – once the price of iron had risen – a new company, the Leven Vale Company Ltd took out the lease. They further invested in the mine, even building a row of stone workers cottages. However, in 1874 the Leven Vale Company Ltd also failed. These short periods of tenancy at Warren Moor Mine were likely due to the poor quality of ironstone which made deep mining unviable.

105 years later John Owen, an enthusiastic industrial archaeologist, and his team undertook an excavation of the site. They not only investigated the standing buildings, but also explored the upcast and downcast shafts and the pumping engine, providing us with detailed diagrams of the interiors of the structures and how they may have worked (Owen’s report can be found here).

What we got up to this time

This excavation was on a much smaller scale than that carried out recently at Combs Wood, with only two trenches around 1 metre wide and 2 metres long to start with. One purpose was to investigate the bank that ran along one side of the river (Leven). It is thought that the bank had been built up by Owen to change the course of the watercourse in order to reduce the damage being caused to the structures. Another purpose was to investigate the retaining wall around the winding engine bed, to discover its thickness and materials used in its construction, and whether there was a direct relationship to the downcast shaft.

Most of the findings from the trenches were in line with Owen’s previous excavations. In the first trench next to the engine winding bed we uncovered the extent of the retaining wall. There was also a lot of evidence of burning with large lumps of slag (metal waste) and a compacted surface layer. We made the decision to extend this trench after we uncovered the corner of a large worked stone. This stone sat just below the topsoil and appeared to be a block from the winding engine bed. This raised a few questions for us – what was this stone doing here on the other side of the retaining wall? had it been placed here purposefully or just discarded?  We also dug two sondages (test pits) to get a full profile of the layers in this trench.

The second trench, up near the standing chimney, was extended far beyond its original dimensions. The aim of this trench was to explore the embankment. Upon removal of the topsoil we found the embankment to be a roughly piled brick feature. However, the more we revealed of the brick work the more we saw a structural pattern emerge. Then, unexpectedly, one of the volunteers revealed two stone door jamb bases, proving without a doubt that there was a previously unknown building! Unfortunately, this was all discovered on the last day, so we weren’t able to explore it any further at this time. This trench also contained the same burnt compacted layer and slag deposits that were in the first trench.

So what happens next?

Another excavation has been scheduled to establish the dimensions and purpose of the newly discovered building!

The volunteers group will continue to maintain the site. In addition, contractors will be working on site into next year to carry out conservation works and make the site safe for public access and enjoyment.

Warren Moor Mine: Part One – the Lime Mortar task

Eleanor Lees – Land of Iron Community Archaeology Intern

For five days back in August a group of very determined Land of Iron volunteers and staff, along with one local lime mortar expert descended on Warren Moor Mine in Little Kildale to begin conservation work on the winding engine bed. During the 144 years since the mine closure tree roots, vegetation, insects and the weather have slowly eroded the site of Warren Moor Mine which includes a winding engine bed. The stonework had very little remaining mortar, and so we took on the task to re-point in order to help protect this historic structure.

Follow this link for a 360 view of the site.

A (Very) Short History of Warren Moor Mine – the story of Warren Moor Mine starts in 1857 when the Bell Brothers of Middlesbrough surveyed the nature of the ironstone in this dale, once isolated but now connected by the new railway. Investigations on the main seam revealed that it was 5-6 ft. deep but split by a band of shale and also had low iron content; only just averaging out at 26% when other parts of the Cleveland area averaged at 30%. The Bell Brothers Ltd declined the mining lease offered by the Kildale estate (landowners) and for eight years Warren Moor remained undisturbed.

Then, despite the results of previous surveys, in 1865, under John Watson and his southern investors, work began on open drift mines into the top ‘dogger’ seam. Drift mining means digging into an edge from the side, horizontally, and is much easier and therefore cheaper than digging downwards. A year later Watson took out a 42 year lease and the ‘Warren Moor Mine’ (Company Ltd) was formed. Letters suggest that the first year of the lease resulted in profit. The ironstone extracted was calcined (roasted to remove impurities) on site and then transported by rail to the blast furnaces. Work began to sink two shafts to intercept the main seam at 220 ft., along with the construction of a steam boiler house and corresponding chimney, a winding engine and a steam powered pumping engine, all to enable deep mining. By 1868, most of the structures had been completed with the exception of the downcast shaft which had only been completed to a depth of 150 ft. but by that time the Warren Moor Mine Company Ltd were in financial trouble no doubt partly due to the poor quality of ironstone leaving the Warren Moor Mines. Kildale estate reclaimed the site and all its equipment.

Four years later in 1872, the Leven Vale Company Ltd took out a lease on the site, not put off by the previous company’s failure to make the site commercial. A row of stone cottages were built to house miners and their families, these cottages appear on historic maps labelled Leven Vale Cottages – in 1972 the cottages were demolished by volunteers from Kildale village and the stone was used in the Village Hall. Regardless of the initial investment into the site by the Leven Vale Company no progress was made with completing either the downcast shaft nor any other parts of the non working downcast mine. The company continued to use the drift mines to mine the top seam but in 1874 became insolvent just like its predecessor.

So after only nine years of operation the mines were abandoned for the next 105 years until 1979 when the archaeologist John Owen and his team excavated the site providing detailed diagrams and explanations for many of the mines remaining features (Owen’s report can be found here)

…And then along we came!

Of course we weren’t the first group to set foot on the site since then, but being in such a remote location it sometimes feels that way. Our task in August was to conserve and protect what was left of the winding engine bed and that involved re-mortaring. We started with a day of training and demonstration at Kildale Village Hall (built with the stones from the Leven Vale Cottages). Our expert, Nigel Copesy, explained the benefits of using a hot lime mortar mix over natural hydraulic limes (NHLs) or other cementitious materials, as well as explaining the science behind the mixing process and why that resulted in better effective porosity enabling buildings to shed water quicker resulting in less damp and decay. He also showed us different ways of creating a mix and some of the more extreme reactions of slaking quick lime.

Over the next four days we undertook the actual task of re-pointing the engine bed. I think we were all surprised at the amount of mortar you could put into a joint before you would feel any resistance! We used three different types of mortar on the different areas of the engine bed in order to provide the best level of protection that we could.

The first mix that we made was used to point the sides of the stonework; it consisted of two different types of sand, brick dust, quick lime, a clay based pozzolanic additive and water. This created an exothermic reaction, where a decent amount of heat was given off but quickly cooled to useable temperatures.

The second mix is appropriately named an earth lime mortar and was used to fill the larger gaps on the top of the engine bed packed with some loose stones. To make this mix a slightly different technique was used. Using some excess soil from a previous archaeological test pit, we soaked it for a few hours before adding some quicklime to give it form. This soil contained high amounts of clay which is known to work well with quick lime. Earth mortars are more common than people realise. Many traditional buildings in the North York Moors and elsewhere have earth mortars at the core of the wall. They allow the building to breathe which can help prevent damp and create a healthy living space.

Our third and final mix was used on top of the earth lime mortar and had a very high pozzolanic value, making it more durable and less permeable. As the top of the engine bed will be most exposed to weathering, the mortar used had to almost repel any rain water. Although this type of mortar would not have been used in this location traditionally; it was thought necessary to adapt the mortar on this occasion to help protect this historic monument into the future, which is now far more exposed to the elements than it was when originally built.

The result of all five days of hard work is a winding engine bed that is infinitely more protected than it was at the beginning of the week. Conserving our industrial heritage is hugely important, especially with a site like Warren Moor which still provides a snapshot in time. The Land of Iron team would once again like to thank the amazing efforts of our volunteers, Kildale estate, and also Nigel Copsey for sharing his knowledge.

Combs Wood – Another Community Excavation

Eleanor Lees – Land of Iron Community Archaeology Intern

After a very wet dig back in May 2017, Land of Iron volunteers and staff returned for a second season of excavation at Combs Wood, Beck Hole in July 2018 to investigate this important iron working and mining site. Luckily for us the weather held – we got to experience excavating in the hottest summer since 1976!

One of the major elements of the Land of Iron Landscape Partnership Scheme is investigating the ironstone industry from the early 19th century to the early 20th century in the North York Moors. Like many of the remains from the iron industry in the area since that time, Combs Wood has been reclaimed by the natural environment. With only 10 days to excavate we had a lot of questions to try and answer…

A Brief History of the site

Combs Wood is part of the Goathland Forest complex which belongs to the Forestry Commission. The site itself lies near the base of Goathland Incline and undoubtedly linked up with this railway line. The incline itself is so steep that in order to get the loaded coaches and wagons up to the top a gravity system was used – water butts were placed at the top of the incline and their weight was used to offset the weight of the wagons. Once the water butts were at the base of the incline they could be emptied and brought up to the top by horses. The horse-powered railway was converted into a steam hauled railway in 1845, and at some point the incline itself was transformed to steam power with a stationary engine at the top. The incline was eventually abandoned in 1865 (after an accident killed two and injured 13) in favour of a more level route, known commonly at the deviation line.

In 1857 that Whitby Iron Company was formed and began to construct the ironworks in Combs Wood. A series of drift mines were opened connected by elevated sets of tramways. The first iron was cast in 1860 and is commemorated by a cast-iron tablet in Whitby Museum. However the following iron working and mining operations were nothing short of disastrous until eventually in 1861 the owners offered the whole plant for sale. Receiving no bids the operation struggled on until a stormy night in 1864 when a landslide buried the two main access drifts, and demolished the beckside tramway and the water leat to the water wheel. No lives were lost but operations never resumed.

Nearby the small Beck Hole hamlet had changed exponentially with the opening of both the railway and the iron works. A row of 33 workers cottages were built corresponding with the workforce and their families. Birch Hall Inn was extended to include a provisions store. In 1860 the inn was licenced to sell ‘Ale, Porter, Cider and Perry’, vital for any workforce. The population boom ended in 1864 with the mines closed and the furnaces dismantled, the cottages were demolished and the only reminder in Beck Hole of a once lively iron industry was the expanded Inn. The ironworks site and associated cottages and infrastructure began to slowly recede under the encroaching vegetation…

The Excavation

Entering the site, we passed the remains of the bridge that once connected the ironworks to the other side of the Murk Esk river and the Whitby to Pickering railway line. At first, the lower part of the site appears to be fairly straight forward. To the right, there is a stone building potentially an office for a manager or clerk. It has two floors with evidence to suggest that the walls may have even been plastered. To the left, there is a wheel pit for a wheel powered by the river that runs perpendicular. We cleaned and recorded the office building as most of the necessary excavation here had already been completed during the previous season.

The wheel pit was another story and there was nothing simple about excavating this feature. which involved navigating the metal poles (cross acro clamps) used to shore up the pit walls, and the daily water removal from the pit bottom. The aim of excavating the wheel pit was to reveal and record the floor of the structure and to gain a greater understanding of its purpose and extent. However, as the excavation progressed, more and more questions about this feature emerged. While we now have a good idea of how the timber water wheel would have worked; we have less idea about what it actually powered. An investigation into a structure on the next level of the site was made to try and see how the wheel pit may have related to other structures on site, including a channel which ran from one level to the next.

Continuing along the tramway we made our way further up into the woods to the upper part of the site which holds arguably more mysteries to uncover. A row of collapsed buildings emerge from the grass to the left and ahead an unidentified structure which was almost completely hidden by vegetation. The first building we chose to explore is the middle of the three larger buildings. It revealed a red earth floor with slag (a waste product of iron working) scattered throughout. The main feature of the room is the ‘forge’ which is still in surprisingly good condition. Theories behind the purpose of this feature on the site are various, ranging from testing the quality of the iron ore coming out of the mines, to creating the horse shoes for the mine horses. To the left of the forge, we discovered an incredibly intact stable floor. The floor shows a drain running along the length of the stable with drilled post holes used to create the wooden stalls for the individual horses.

Starting Them Young

On the first Saturday of each month the National Park Authority run the Moors and Valleys Young Archaeologist Club (YAC) for young people aged 8 to 16 years. For the July session, the club joined us on site at Combs Wood to experience a working archaeological excavation. The children were treated to an in-depth tour of the site and also got to sieve through the spoil heap to find any artefacts that the volunteers and staff had missed. The club did very well, discovering tile, pottery and even a nail.

Our Amazing Volunteers

The amount that we achieved in just 10 days is astounding and a credit to the work ethic of our volunteers. Not only did they shift tonnes of soil and stone they assisted with the public tours, and provided knowledge and insights which helped establish a greater understanding of the site. Without them the excavation would just not have been possible.

Thanks also to the Forestry Commission for permission to keep excavating.
