Mapping a Moss of many layers

One of the main artistic outputs from the Moss of Many Layers project is the map of Bolton Fell Moss created by Helen Cann. This post put together by Harriet Fraser gives a behind-the-scenes look at Helen’s process, and how the map came into being.

Helen’s map not only shows the history of the moss, but also the present, documenting the ongoing upkeep of the Moss, and the hoped-for future as restoration brings rewards.  The layers of time – past, present and future – were important in Helen’s thinking.

The map shares stories from local residents and insights from scientists, and portrays the wildlife communities that have returned to the moss since extraction ceased and are likely to thrive as their habitats improve. It’s a thing of beauty, something that draws you in.

When the original map was shared at the Wide Open Day it was like a magnet – people gathered around it, pointed out things they recognised, new information that surprised them, and used it as a catalyst to share further stories. The map is hand-drawn, in wonderful detail. When further infrastructure is in place on Bolton Fell Moss, and accessible via the boardwalk, a reproduction of the map will be in place. We can’t wait to see it there!

Helen’s process

Helen compiled the map over a number of months. As well as visiting the site (which she reflects on in her blog here), Other artist researchers in the team shared recordings with her, so she could listen to interviews with people who used to work on the site when peat was extracted and ecologists and rangers who are now monitoring recovery of vegetation, and the return of wildlife. And Helen had conversations with the scientists, restoration specialists and others on the Moss of Many Layers team. This approach is new to Helen, and it’s great to see how rewarding it has been.

‘I have rarely worked with an inter-disciplinary team before other than being given access to historian or curatorial research notes, for example. Moss of Many Layers gave me the opportunity to have face to face talks with experts. The site visit was fantastic and vital in understanding the land and being able to have conversations with experts in the field.’

The inter-disciplinary nature of this project impacted the approach of all the researchers, with a level of responsiveness that relied on iterative learning and conversations. ‘My experience as an illustrator means my practice involves following a brief and then delivering as near to the agreed brief as possible.  In this case, I created my own brief and then followed through.’

When we talked about this, Helen reflected that this is quite unusual – but worked perfectly. Each artist began with a loose framework (in Helen’s case, to draw a map) and then let their work evolve according to ongoing learning from visits to the site and from other people. Helen’s visit to Bolton Fell Moss caused her to change some of her initial ideas (and do a fair amount of rubbing out!). This doesn’t happen often in her work. ‘In the future, it might be good to allow myself space for more ‘idea bouncing’ and the flexibility to change course from the initial brief if my thoughts develop or I’m inspired to go in other directions. In general, I’m not sure how acceptable this is for stakeholders if they’ve a been promised a particular outcome – I’d never do this as an illustrator but it’s good to know how/if this works within an art context.’ Perhaps this is a key difference between pure illustration and research-led illustrative artwork, where the shape, detail and overall feel of a piece, can alter along the way: it’s responsive. You can read more about Helen’s reflections on her process on her website here.

One of the aims of the Moss of Many Layers project was for the various pieces of artwork to reflect learning, rather than an aim for a predetermined outcome. We’re really happy that this is what happened – and when all the work is compiled and made available we’ll share a link to it through the project page.

Encountering the unexpected

I asked Helen if anything unexpected happened for her. This was her answer:

‘ – the realisation that the Moss was in a constant state of flux, was still a work in progress and that I’d need to adapt drawings made initially as thoughts and practice had changed over the months.  I’m used to maps becoming anachronistic over time but never within such a short time, and I have to acknowledge that some elements of the map may be out of date by the time it’s actually printed as a sign!’

This might be a little unexpected in the context of creating an illustration, but it is an encouraging reflection: now that extraction has come to an end and restoration work is beginning to have a positive effect in the way water balance is shifting on the moss, the process of healing is showing quick results. It’s part of the positive story of this place – the geographical location won’t change, but a lot else will.

And a final word from Helen? ‘It’s been a blast.  I learnt loads and am really pleased with how the map turned out. I wish I could have had some of that cake.*’

Shifting grounds – mapping Bolton Fell moss

Guest Blog from Helen Cann

As part of the NERC-funded ‘Moss of Many Layers’ project, Helen has been commissioned to create an artist map of Bolton Fell Moss – a 400-hectare site that has experienced large-scale peat extraction and is now being restored. Helen’s map will show the bog’s industrial peat cutting heritage, ongoing restoration, and its future state as a National Nature Reserve, which will also be a massive carbon sink.

Helen has been busy researching from a distance, and has been talking to other members of the Moss of Many Layers team and was finally able to visit the bog to find out for herself just how it looks and feels. The  blog is Helen’s description of her day there last week when she visited with Rob Fraser (photographer).


“We walk over the old milling grounds to the Reserve Field, the four of us – the current warden, the volunteer (an ex-warden), the artist and mapmaker. Most of us know the lines of this land. I do not.

I have mapped it in my head, of course, researching online, digitally flicking through the yellowing pages of ancient books written in Cumbrian dialect and old land documents. I have an idea of Bolton Fell Moss but, like those papers viewed through a screen, that idea misses any kind of real life energy.

Now I’m here.

An image showing dried grasses and exposed, dark peat, extending into the distance: a raised bog.

It’s different to how I’d imagined. Wide skies. Less bleak. Parts are still scarred a burnt black, as if scorched. The evidence of peat milling shows as giant scrapes across the land but in places, those lines are softening with moss and rush, or silvered with water reflecting the early spring clouds. The landscape has shifted to something else over the past few years as it’s started to recover.

We stand on the Reserve – the small part of the Moss that was untouched by industry. To demonstrate the surface instability, the warden and the volunteer jump up and down. As they land, I watch ripples spread out across the mounds of moss like a small earthquake. This whole world feels like a strange but perfect animal – part plant, earth and water and forever moving. The sphagnum moss on the surface holds water like a sponge, keeping the peat underneath it wet; exactly how it needs to be for the bog to act as a carbon sink and for its delicate ecology to survive.

We walk further. It’s clear we’re not alone and share this space with many others. We hear the bubbling call of the curlews before we see them. Blunt tailed, they fly as a pair, their scythe-like beaks almost half the size of their bodies. They’re an unlikely-looking bird for sure.

A hare sits against the black earth in the distance. She turns her pale eyes towards us – and then she is gone.

Against the sphagnum and the silver heathers basks an adder, his back a graphic pattern of blacks and whites. The bog trembles as we step closer. The snake must be able to feel us but the sun is too seductive and he flattens his body some more against the highest hillock. We walk on. When I turn back, I’ve lost him, camouflaged against the grey of the ling. The warden finds the spot again, practised in reading the mounds of moss like a sailor can read the waves.

The volunteer and warden offer to take a core from the bog for us. A huge pipe, open on one side, perhaps a couple of centimetres in diameter and many metres in length, is slowly twisted into the ground like a corkscrew. The pipe is pushed down through, perhaps, 8 metres of peat until it hits the bottom. They pull it out with a cheer, as if unbottling champagne. Inside the core it’s clear to see the layers of peat changing in colour and texture as climate and interaction with the land has changed. This place has always been shifting.

At the very bottom of the core sits grey glacial mud full of tiny stones. It comes from a shallow lake that must have been here during the Holocene. I scrape some of the clay out and ball it in my hands, pushing my thumbs in to make a simple pot. An age-old human interaction with the earth.

A woman and two men are looking at a peat sample taken from 9 metres beneath the surface of a raised mire.

The colour of the layers in the core rises to warm, wet browns of moss and plant debris that once fell into that lake, eventually to compact and create peat. I find an 8,000 year old birch twig, its bark still preserved, and the husk of a seed, the ghost of a life.

Rob and I tread the boardwalk to a small central island of trees to take photographs. The boardwalk is being relaid and there’s a smell of fresh cut pine. It mixes with the yellowgreen scents of the Moss, cut with sharp ice off the Fells and the warmth of valley silage. The wind brings the calls of lapwing and greylag geese.

We sit on a massive bog oak that reclines languidly now, although at one point, no doubt, it was pulled roughly from the peat as inconvenience to the digging machines. Its dry, silver bark reminds me of the patterns of moth wings.

I look out over the site. It’s a work in progress and will be for decades to come. Ideas are being trialled and constantly readjusted to calibrate to a shifting environment’s needs. The belief in the restoration of Bolton Fell Moss as a carbon sink and nature reserve is unwavering for the future though, however long it takes.

Now I’m here, I’m less certain of my first map drafts – I will need to change them as the restoration work and the bog itself have changed from my initial understanding. I have to accept that this is a place in flux and my map can only be a document of this landscape at one particular moment in time.

I’m happy, though, that I can take some stories from the Moss today, stories I might never have heard had I not visited. On the map I’ll include the larks and the lichen, the creaking frogs in the rushy pool, the voices of the warden, the volunteer and the artist. The science. The history. The hope. They all add to the multi-layered understanding of a place – to be used in a map that’s not simply a reductionist document of roads or territory.

The world’s climate is shifting now; and so must we. We have to find ways to capture carbon and prevent carbon release. Restoring bogland will help us do that, so in order to encourage this equally shifting landscape, this forever changing land of peat and water and moss, we must learn to shift with it too. And on a personal level, on coming to Bolton Fell Moss, I recognise that my own ideas have shifted and subtly, with them, so has my own world.

We walk back to the car. The yellow sunshine-faces of the coltsfoot flowers smile up at us.
