Mapping Mountains – Trimble Surveys – Way Stone Edge

 

13.04.26  Blake Moor (SD 971 212) 

Blake Moor (SD 971 212)

Over recent times, trips to the moors above Burnley have taken place twice a year; usually in April and October; one where the greenery and springs warmth is beginning and the other when autumnal colours are predominant.  As with most planned trips in Britain they are weather dependent and especially so for hill walking.  This visit was no different with heavy localised showers forecast for the first day of our two day visit and rain heading up from the south during the afternoon of our second day.

I drove to Mark’s and he then drove north to meet John outside the White House pub at the top of the A58 road.  On our way we had a detour in and around Rochdale to acquaint ourselves with the splendours of this town.  It’s always good to see Mr Kirk and once parked and the customary hand shakes and hugs were had, we were soon happily seated in the pub for a lunchtime meal.  Afterward it was time to visit the hill. 

Meeting place, meal and the start of our walk; the White House pub

Our chosen hill for the day was Blake Moor, which is typical of much of these hills as it’s dominated by open surrounds and consists of heather and moor grass, with an occasional rock outcrop adding interest.  After our meal I quickly got my walking boots on and headed up the road and through a gate to join the good track leading northward beside the Blackstone Edge Reservoir. 

Our inward track

If not for this track and its continuation the hill would be a wild affair with much heather and no doubt bog to walk through.  However, the track gave a semblance of serenity to the surrounds as it made its way north leaving the first reservoir before joining the next three; these are the Little Hazzles Reservoir where a pair of Canada Geese croaked their annoyance of vacating their spot on the track as we approached.  The other two are the White Holme Reservoir which we visited on our downward route and the most northerly; the Warland Reservoir.

I’d set off wearing trousers and light fleece coat but the open skies with blue and intermittent cloud meant I was soon over heating.  By now John had caught me up and as we waited for Mark I took the opportunity to convert my trousers to shorts.  Waiting beside one of the reservoirs proved a welcome few minutes rest before we continued toward the southern edge of the Warland Reservoir, here we followed the continuation of the thin ribbon of water that constitutes the Little Hazzles Reservoir, before leaving the welcome confines of the track and heading up in to heather and moor grass for a direct approach toward the high point of Blake Moor.

By now dark grey shower cloud was massing to our east, with little wind the showers were no doubt slow moving.  As the track petered out we followed a semblance of a path as it headed up on to the higher moor.  The high point of Blake Moor is approximately 200 metres south-eastward from a triangulation pillar, which had been a prominent white indicator on the horizon during much of our inward walk.  We were soon on the top with much of the hill consisting of the customary moor grass and heather. 

Heading for the summit

As this hill had been LIDAR’ed I had no intention of Trimbling it, but still placed the survey equipment on top of my rucksack on the high point of the hill for the customary summit photograph.

We debated heading back the same way, but decided on following a fence roughly south-east down to the eastern end of the White Holme Reservoir, with a path on the western side of the fence giving encouragement for a relatively easy downward route.  This would also give us a circular walk instead of the there and back option. 

On the track beside the White Holme Resrvoir

By the time we reached the track on the southern edge of the expanse of water I was in head down and plodding mode.  We only stopped occasionally, for me this was to take a photo looking across the waters or toward the distant hazy spires of Manchester which stood out on the horizon.

By now my two colleagues were slowly pulling ahead leaving me to my own devices.  Initially I was in no particular hurry, although the threatening build up of late afternoon deep grey shower cloud made me quicken my pace, with the easterly mass of cloud still lingering, but now showers were breaking out closer to where we were.

I made it back to the awaiting cars where John and Mark were getting their boots off, dry from any threatening rain and happy in the knowledge that another hill had been visited and partially explored.

Mapping Mountains – Trimble Surveys – Arenig Fawr


13.12.25  Ffridd Trawsgoed (SH 837 328) and Moel Hafod yr Ŵyn (SH 841 322) 

Moel Hafod yr Ŵyn (SH 841 322)

There is bleak beauty in venturing on to rough, unremitting ground and especially so during the onset of winter where grey skies predominate and a brisk wind echoes across the land.

Today we visited two hills positioned just west of the southern most part of Llyn Tegid.  Both are relatively easy to access from the narrow road that winds its way across these hills toward Bronaber.  I hadn’t been on this road in many years and had not until today visited these two hills.

I met Mark and Aled in Y Bala, where we left two cars and then continued on the A494 road heading south-west beside the lake toward the minor road that in time would take us to our designated parking spot on a grass verge beside an old metal gate. 

Heading toward the forest track

The forecast gave south-westerly winds, so not chilled and relatively mild for the time of year.  I set off before Mark and Aled, but soon stopped and waited as the continuation of the way up the hill was indistinct with slender long grasses amongst bracken and stunted trees giving little indication of a path.  However, one did exist and once on it I followed my companions up to a forest track that shortly afterward bisected another track where a person was standing beside a gate.  As we approached we said hello; Andrew Graham was the landowner, his sister was standing a short distance further down the track.  We chatted for five minutes or so, he was concerned as the gate had been left open and wondered who had done it.  He’d come to the area in the 1960s having bought the land to turn it over to the conifer plantation that now surrounded us. 

Andrew Graham

As Andrew walked down the track to join his sister, we headed in the opposite direction looking for a convenient access point on to the upper hill, which now rose in front of us a mass of heather and roughness.  The going uphill from this point was steep and ponderous with no semblance of path.  It was hard work, but also a marvelous place to find oneself on a Saturday afternoon in December. 

The steep heathery slopes leading to the summit of Ffridd Trawsgoed

I arrived on top last out of the three and was immediately buffeted by the brisk wind.  Although I’d brought the Trimble I had little intention of using it unless the tops were covered in clag and then only as a hand-held GPS device.  However, I still placed it on the high point for the customary photograph. 

The summit of Ffridd Trawsgoed

To our south Moel Hafod yr Ŵyn looked a wild inviting hill, with a rather unpleasant bog between us and it.  Leaving the summit we stumbled our way down the steep pathless slope and back on to the relative comfort of the forest track.  However, the comfort didn’t last long as soon the bog would have to be tackled. 

Moel Hafod yr Ŵyn and its unsavoury looking bog

There’s a pleasing aspect to bogs.  Many are lush with copious amounts of undergrowth and this one was definitely one to savour.  Progress through it was never difficult and wearing vibram soled wellies certainly helped.  I followed Aled as he furrowed his way through, only stopping occasionally to regather my breath during which I looked at the slender threads of long grasses as they gently danced in the wind.  As I said; there is beauty in a bog. 

Mark tackling the bog

Mark soon joined us on the other side of the bog and as Aled headed up to gain height, Mark continued flanking the upper hill on the periphery of the bog before then heading up toward the summit cone.  Oh decisions decisions, what one to follow?  I opted for Aled and was soon being left behind as I made slow progress through the undergrowth.  By the time I spotted Mark he had gained height and was approaching the upper part of the hill, Aled was already nearing the summit.  I continued my slow plod up in to the realms of wind and views.

The upper cone of Moel Hafod yr Ŵyn

The upper hill proved a delight with a small rock band to veer past.  Having reached the summit I did as I had done on top of Ffridd Trawsgoed and placed the Trimble on the high point for its customary photograph.  The view compensated for my tiredness, with the land to the west a wild and remote place of more tussocks, bog and rising hills, whilst to our south-east the descending slopes headed down to the gentler climes of the valley below. 

The summit of Moel Hafod yr Ŵyn

Leaving the high point I followed Aled down through mixed ground of heather and intermittent hidden rock.  Our route down led to a wall which had a barb wired fence perched menacingly on top of it.  This was not good news for the two elderly gentlemen in our walking party.  However, with the help of our younger colleague there was no mishap and soon we were standing on relatively safe ground on the other side. 

The last steep slope leading back on to the narrow road and the car parked beyond

From here it was only a short walk back to the car; with an initial steep slope leading on to the narrow road where we veered right and followed the thin width of tarmac a few hundred metres back to where we had started our walk from.

We were back in Y Bala at around 4.40pm and soon happily seated in the Plan yn Dre for an early evening festive meal, which proved an excellent way to end another good day on the hill.

22.10.25  Soil Hill (SE 076 313) 

The track leading toward the summit of Soil Hill (SE 076 313)

Hills come in all manner of shapes and sizes.  Many are wonderful inventions of nature with eloquent spires reaching skyward and plunging drops below.  Others are tranquil in their profile, adding a semblance of peace to their shape.  Some in Britain can be quick affairs to visit whilst others afford a whole day’s endeavours.  There are few hills that do not leave a good impression.  Sadly Spoil Hill is one.

I suppose our chosen route of ascent from a high narrow road up a green track leading to a high mast didn’t add much quality to our experience of the hill.  But, even though the green track, which we were on for only the fleetest of fleeting moments was rather nondescript, it was much better compared to what we encountered on the summit.  This is a bi-product of mans disposal efforts and seems to have increased in height over recent years with the debris of all manner of stuff poking up out of the rather apt summit soil.

There’s not much more I can say really.  Thankfully during our walk, and considering how many heavy showers were still lingering, we remained relatively dry, which helped.  I did get a photo of the Trimble perched on top of my rucksack, although I had no intention of gathering summit data, as LIDAR would be sufficient and a lunchtime meal called. 

John and Mark heading down from the summit

It was good to bag another summit; it did have extensive views from its top and it was good to be out on the hill, but otherwise it was a summit that will not linger in my memory for anything else except for its ability not to make a good impression.

Mapping Mountains – Trimble Surveys – Pendle

 

22.10.25  Nab Hill (SE 033 323) 

Nab Hill (SE 033 323)

Nab Hill can give an easy ascent, however if not for the aid of LIDAR, Abney Level and hand-held GPS equipment you could wander the summit area visiting a multitude of lumps and bumps trying to determine which in fact is the highest.  This is due to the debris of old mine workings.  Outside of these, the upper hill is typical of the area with heather dominating on an open moor.  Nowadays it also has a number of scattered wind turbines beyond its trig pillar, with the latter positioned on one of the lumps eastward from where LIDAR indicates the high point of the hill is situated.

When we set out flashes of sunlight enhanced the opposing moor across the minor road where John had parked.  The rusted colours of autumn were on grand display as the sun highlighted slithers of green amongst the golden yellows and oranges.  Although delightful to look at, it also looked horrifying to walk through as patches of standing water led the eye toward Warley Moor Reservoir, which added stillness to the scene. 

Autumnal colours beside Warley Moor Reservoir

Our way up was in the opposite direction to the reservoir, either over or under an intervening blue barred metal gate that led to a wide green track that took us in to the upper hill.  Ahead and on the near horizon was a forlorn looking wire fence with an immediate drop in front of it, no doubt an abandoned hole from the various workings hereabouts. 

The green track leading to the hill

I left before John and Mark, slowly gaining height as flashes of sunlight struck the land.  This time of year can give dramatic effect when on the hill with low light and succulent colour the order of the day.

Prior to visiting John’s, I had noted the LIDAR position for each of our planned summits, but on this particular small walk I only got the Trimble out to zero in to the summit location as I crested the upper moor, having walked past the quickest route to the top whilst aiming for what looked like a good possibility which vied for high point.

Having crested the moor I took a series of photos as John followed by Mark roughly followed my inward route.  As I did so the grey murk behind us and to our west looked rather foreboding, it was almost black and no doubt heralded the next heavy patch of incoming rain. 

Mark on the way to the summit of Nab Hill

Before leaving this spot I checked the LIDAR co-ordinates for the summit against what the Trimble was showing as my current position, and then continued following the dilapidated fence around the rim of moor to what was becoming evident as the high point of the hill.  This consisted of a welcome patch of greened grass situated amongst the debris of old mine spoil and the heather of the moor. 

Mark and John joining me on the summit of Nab Hill

The summit was a tranquil spot to wait for my two colleagues who quickly joined me.  Before leaving I positioned the Trimble atop my rucksack which would normally form the survey position.  Today however, with the heavy rain fast approaching I had no intention of gathering summit data, LIDAR would have to suffice.

As I packed the Trimble away and gathered up my rucksack the first drops of rain skidded our way.  My brolly, which I carry on most small hills when weather dictates, was soon up shielding my camera equipment, the Trimble and the majority of myself.  It was only a short walk back to the car and when we arrived the heaviest part of the shower was over, affording a semblance of dryness to sort gear and head off to the next hill.

Mapping Mountains – Trimble Surveys – Ward’s Stone

 

21.10.25  Bowland Knotts (SD 727 606) 

Looking toward the old summit location of Bowland Knotts

Recent trips to the moors above Burnley have given a mixture of blue sky, warmth and autumnal colours.  All trips have been dry, with not a speck of the wet stuff falling from the sky.  This scenario changed on our latest visit to John Kirk’s.  The weather forecast warned to expect fast moving showers with rain in between, and it didn’t disappoint.

John had planned our two day stay with easy ascents and numerous meals out, which seemed a good combination, and especially so as any prolonged walk would involve getting well and truly soaked.  It was a matter of getting out and trying to time our ascents for a spell between the frequent showers and hoping to remain relatively dry in the process.  However, hoping to do so is one thing and what was encountered is another. 

Not my favourite weather conditions

Our first hill of the visit was Bowland Knotts.  The summit of this hill was relocated in December 2013 when the 1st edition of the The Fours was published by Europeaklist.  This was at a time before LIDAR was being used to analyse numerical data.  This relocation was subsequently confirmed when LIDAR became available for this hill.

The summit relocation eased its ascent, if indeed that is what is wanted, and today it certainly was.  Its old listed summit is positioned beside the trig pillar and south-west from where a narrow road crests these hills.  It’s an easy ascent from here to the trig via a couple of small lumps on the way, following in the main a solid stone wall that keeps to the crest of the ridge.  However, its highest point is even closer and just eastward of the high point of the road.  A brisk walk up and down wouldn’t take more that ten minutes and that’s stopping on the summit to take the customary photographs of extended views whilst bathing in the delights of blue sky and warmth.  In all it took us 41 minutes to visit the high point and get back to the relative dryness of John’s car.  Only two of us made it this far as the third was the sensible one and remained in the car after we realised that our initial endeavours had taken us in the wrong direction, and even then we didn’t get to the high point of this section of ridge.  We thought we had reached the summit; having set out in wet and windy conditions following our confidently striding local guide, who unbeknownst to the two incomers was going in completely the wrong direction. 

Following our local guide toward the trig pillar

Navigational errors can easily be made, but you would think that three experienced hill walkers who between them have completed the Munros, English and Welsh 2,000ft’ers, and in the case of one of the incomers the Welsh ones on multiple occasions, the Deweys for two of them, the other one didn’t venture into England and just completed the Welsh ones, for one of them the Welsh Humps and between the three numerous other lists, would have enough gumption to realise that following the ridge in the direction of the trig pillar was in fact incorrect, and that the true summit was in the opposite direction on the other side of the road.  Well, they eventually did, but it took them a while to fully comprehend this. 

Heading toward what we thought was the high point of the hill

The realisation of our incorrect wander only happened when back in the car having got wet from the initial endeavours.  When the error of our ways was realised I laughed, only a bit mind, as this now meant another journey out in to the particularly inclement weather conditions.  Thankfully it was only a short distance to the summit via a small section of road, a cattle grid, a wet bit of ground and an attractive rising lump that took me and Mark to the high point.  John was sensible and remained back in the car.

I had just enough time to try and take a photo with the inconvenience of ‘memory card full’ flashing on my camera screen.  I could of course stand and fiddle about finding a new one and inserting it in the camera for a couple of quickly taken photographs, but it was wet, it was windy and although my brolly had done an excellent job of keeping me relatively dry it was also cumbersome to try and do anything else except for walking with it when it was up.  However, I did take a couple of Mark on the summit with his mobile phone.

I arrived back at the car feeling unusually invigorated and with a broad smile on my face.  Still wet though!
