I like collecting things. Triangulation points are a favourite along with benchmarks that can be found along a walk or near to one.
There is something very satisfying about reaching a trig pillar, partly I guess because they invariably involve a walk up hill and a reward of sweeping views, weather permitting. There are 84 pillars within the Peak District National Park boundary and many more triangulation points and thousands more benchmarks.
Some are not shown on maps with the traditional blue triangle, the one at Hey Edge for instance, built but never used for triangulation, but was used for levelling, so does it not qualify for the blue triangle.
Some triangulation points are not even pillars. One of my walks takes in the Hunting Tower on the Chatsworth Estate, the triangulation point being the flagstaff. Another is the centre of the spire of All Saints Church in Bakewell.
With the advent of GPS the triangulation pillar network became largely redundant, but a few still do have a purpose. The pillar at Harland South, levelling bracket number 2998 is part of the Global Positioning Network and as such is protected by Ordnance Survey. A plate informs the visitor that any damage should be reported to the phone number.
Triangulation points always come in a minimum of three so a favoured walk of mine takes in the Hunting Tower at Chatsworth, the pillar at Birchen Edge along with the Three Ships and the pillar at Harland South, passing Hobs House, one of the first ancient monuments to have legal protection in the UK, on the way. Two pillars, one part of the Global Positioning System and one flagstaff on a hunting tower. Not bad for a day out.
I had a day out on the high moors of the Dark Peak last Friday. The more I visit this area, the more time I want to spend here. In large measure it is the desolation, the quietness. No paths on a map mean very few people, long windswept views and time.
Just after the trig I sat on a spot height and just looked at the landscape. Following its contours with my eyes, seeing the shapes, curves, how sensual the wind and rain have made this moor with its rises and falls, like the shape of a woman laying on her side.
Following the curves with my eyes colours started to split, it wasn’t just brown, there were greens and orange, flame reds, yellows the black oily ooze on the surface of the peat, iridescent with blues and purples. The moor is dotted now with the vivid green, almost fluorescent, shock of Sphagnum Mosses, planted to hold the water there and regenerate the peat. It really is a shocking contrast in the midst of all the earth colours. Soon white cotton grass will bud near the mosses, splashes of white, like an impressionist painting. A double rainbow arched over Grinah stones against a deep powder blue sky, that changed with each new front of the storm, the sky shifting from blue to white to gray and then deep black.
Then the smell of the moor. The first I detected was of the peat, it was reasonably dry where I sat but the peat gave up its scent, earthy, metallic, primal. An old tree stub poked out of the peat bog grey and stark against the black peat backdrop. As I sat I became aware of another more powerful smell. Sea air, brought in off the west coast by the storm. It was heavy with sea salt and I was immediately transported back five decades to the end of the south pier at Blackpool and the smell of the green salty sea. I faced the wind and breathed deeply savouring the salty taste.
Last year I started to collect all the Ordnance Survey triangulation points in the Peak District National Park boundary. I am about half way through now, although it was supposed to be finished within the year, but the days ran away with me.
There are 94 points if memory serves me correctly. The points are buildings, surface blocks, pins and the king of all tick list features, triangulation pillars.
I try to do a walk that includes 3 points, hence triangulation, its a bit of OCD within me that likes uniformity, it wouldn’t seem right doing four points.
Doing the research is fun, I didn’t know actual buildings could be points, but it makes sense. Bakewell church and the Hunting Tower at Chatsworth are two good examples. High with good lines of sight. I looked a bit weird in the Church with my GPS outstretched moving around one pace at a time, looking at my hand then looking up at the spire, and this was inside too.
Finding a surface block in thick undergrowth is very satisfying as is navigating to a pin. Some I have had to go back to as time has caught up with me before I have found them.
The best feeling is reaching a triangulation pillar. It generally involves an uphill slog, sometimes via a circuitous route, often with the pillar staying out of sight until the last few hundred meters. I think the hard work getting there is part of the joy I feel once I am at the spot. Then there is the view and searching for the, at least, other two that should be able to be seen in the distance.
Some of the pillars are a bright white, some have the lovely mottled concrete surface. Some have been adorned with plaques, some have graffiti. There are some that have been obliterated all together and some that lay forlorn away from their original site. Some hide in hedges, all pristine as the day they were made.
A summers day in a field, sat by a trig pillar that nestles in a hedgerow, eating my sandwiches while birds twitter on and the view looks all sky blue and green grass is one of the happiest ways to spend a few hours.
This is a levelling benchmark placed and used by Ordnance Survey. Its location is SK 2305 8759 at Moscar on the footpath from the A57 towards Stanage. The mark was made in 1961, is of the third order of surveying and is 600mm above ground level. Its datum is Newlyn. Originally the mark and boulder were on the west of the footpath but time and boots have now placed it east of the path.
There are some 500,000 benchmarks on the UK mainland, most no longer in use. They identify the height at a given point. The base line is the tidal measuring station at Newlyn in Cornwall, that is the point where all height measurements are taken from, including the 190 Fundamental Benchmarks which were the first order and therefore the most accurate, set in chambers deep underground on bedrock , these benchmarks are still in use today by the Global Positioning System for calculating the accuracy of the height calculation.
Not all triangulation points have a triangulation pillar or a benchmark plate. The latest walk started at the Grade 1 listed All Saints Church in Bakewell, the triangulation point being the church spire. The church is interesting for its architecture and stained glass windows, the local benefactor and landowner features large in the proceedings. From the church I headed south east for the next trig.
Noton Barn is at the top of a small rise overlooking Bakewell and Haddon. Tracks and pasture land make the walk a pleasant stroll especially on a sunny day. The triangulation pillar itself is situated in the corner of a field, unadorned and in perfect order. Heading back across the fields to the next trig there are wonderful views of the medieval Haddon Hall estate, which is reached following a short descent to the A6 road.
The route rises from the road, through the Haddon Estate and on to the Chatsworth Estate. Climbing up the hill and through the trees, a rail tunnel, now sealed is passed. The tunnel was used to hide the rail line from Rowsley to Bakewell from the sensitivities of the Duke of Rutland who owned Haddon Hall. The Monsal Trail starts at Bakewell and continues on to Topley Pike east of Buxton, it is a fine walk or cycle especially now that the tunnels have been opened and floodlight during daylight. Calton Pastures sits between Bakewell and Chatsworth House, nestled against a wall, with views across to Edensor and Chatsworth Park. From the trig it is a simple and pleasant descent back in to Bakewell. The route does cross a golf course, and a large bell has to be rung to warn golfers of your presence, this is very satisfying, especially if one can time the ringing in the golfers mid stroke, such pleasures should be taken whenever they can be had.
The classic walks of the Dark Peak offer the walker enjoyment of the highest order whatever the weather, come rain, snow or sunshine. The degree of isolation especially in winter when on a featureless high moorland deep in snow that is invariably being driven hard into the face by an unremitting wind, is a character building experience best savoured in warm surroundings with a hot mug of tea. The walker having endured such a day will quite rightly have earned the soft green hills of the White Peak the following spring.
The walk along the three triangulation pillars that look out over the Upper Derwent Valley is one of the great edge walks of The Peak District. It is not a long walk so there is plenty of time to stand and stare, or, better still find a vantage point and sit and watch, there will be much to view and learn.
I started from The Kings Tree at the end of the public road that winds its way up the valleys western side. A track leads across the young Derwent river via the Slippery Stones bridge, transplanted from the sunken Derwent Village, and heads off up the valley following the river. Above can be seen the edges that fringe the valley and it is to one of these that a shooting track climbs up from the river towards Crow Stones Edge and then onto the first trig at Outer Edge.
The views from the triangulation pillar are magnificent. Bleaklow, Kinder, The Great Ridge, Bamford Edge, West and North Yorkshire, all are there to be seen and no doubt on a crystal clear day well beyond that as well.
The next triangulation pillar, Margery is in line with the valley and in a dry season is a pleasant walk, in wet and continuous rain it is a completely different matter. This is peat grough country, dark, thick, oozing, leg sucking. There is no avoiding it, so you might as well be prepared. Gaiters are a must as are tight laces to save lost boots. You can skirt some groughs but a strange and probably natural mathematical formula means that you can never ever escape the final ignominy of flailing about in a childish fashion whilst trying to look as though you are in control. It is also a natural law that having seen no one all day, as soon as you become stuck a ramblers group will appear out of nowhere, to ask if you need help, to which the answer is of course a firm NO.
From Margery I chose a little bit of a nav exercise, taking a bearing from Featherbed Moss to the shooting track of Dukes Road means a yomp across moorland, navigating between the wetter marsh areas to gain the track across Cartledge Bents. Near by is an old cross possibly used as a marker to the Grange at Abbey Clough nearby and well worth a visit.
The slabbed track for Back Tor which can be seen on the skyline, threads through peat and bog, so at least the feet keep dry. I’m not sure about these paths, I agree they do reduce erosion and something had to be done, but they are sore on the feet, so I was glad on reaching Back Tor, to climb up to the trig, remove my boots and sit back and relax.
The vista really is superb, I was glad I had brought some binoculars so that I could watch the birds and hares and pick out favourite places on the horizon. After half an hours rest I set off down to Fairholmes visitor centre via moor, woodland and track, a great days walking whatever the weather.
Spring for me, always heralds green pastures, rolling hills, white limestone, heavy showers and blue skies. It means for a period of walking in the White Peak where there is a release from peat bog, groughs and bleak desolate moorland. The winter slog slips away to be replaced by a warming sun and longer days.
I chose the boundary between dark and white, strolling up from the plague village of Eyam towards the north and the dark. Eyams an interesting place, one of Ranulph Feinnes heros for their selfless act of sealing themselves off from the outside world when the plague arrived, you can spend hours there tracing out the tragedy, just don’t go in tourist season.
My first trig objective was Sir William Hill, which gives wonderful panoramic views across the whole of the Peak District. Its a gentle climb out of the village, through woodlands and across green pastures, at one point you pass an abandoned lead mine, redundant industrial buildings incongruous in the landscape. A large badger set protects the trig from the Eyam approach and the dogs spent long moments with the snouts down the entrances trying to figure what the scent was. The eye can see right up the Derwent Valley, across to Kinder and Bleaklow, down to Bakewell and across Froggatt and Curbar edges. I sat and took it all in until two people arrived and I left to let them have the trig and the views in peace.
I headed out to Abney Moor via Bretton Clough, a secluded valley sitting between the gritstone and limestone. The Abney Moor trig requires a degree of stealth, although I did not know this at the time. Crossing moorland to reach a stone wall that surrounds the glider airfield a decision has to be made. Do I hop over the wall and hope not to be noticed, or take the long walk round to ask permission. I know which is the right way and after choosing my course of action I strode through the gate that gives access to the trig from the airfield. There is a little plaque on the trig, placed there by the glider club, which is ironic as they refuse access to land based mortals. The views out to Castleton, Mam Tor and the Great Ridge are superb, below is industrial farm buildings blotting the landscape and filling every green patch with junk and rubbish. The sign on this side of the access gate stated no access to pedestrians, so I skirted the wall dropping down to reach a track that took me to Great Hucklow and the door of the pub slammed in my face just as I was about to enter, lovely people.
Head south along old walled trackways through rolling pasture, true limestone country this, the eye seeing for miles, and aim for Wardlow and another stealth trig, protected by drystone walls and gated farmland. No easy access and definitely walls and fences to climb over. This trig a high point in the land around, the vistas long and low, I sat in the fading light, my back to the pillar and just watched. A bird of prey, I could not tell you which, soared up from Cressbrook Dale and quartered the land.
A long walk back to Eyam across pasture and through squeeze stiles, entering Eyam from the old Tideswell Lane and then along quieter streets to the end.
