Mapping Mountains – Trimble Surveys – Aran and Y Berwyn

 

24.04.21  Braich yr Hwch (SH 877 233), Foel Hafod Fynydd (SH 877 227), Esgeiriau Gwynion (SH 889 236), Foel Rudd (SH 895 239) and Ffridd Cwm Ffynnon (SH 891 250) 

Braich yr Hwch (SH 877 233)

The high Aran are impressive hills.  From the east their profile always stands out.  Dominating this range of hills is Aran Fawddwy, which south of Yr Wyddfa is the highest point in Britain.  When I first started hill walking the Aran drew me in along with Cadair Idris and the higher Eryri peaks to their north.  But it was the Aran that I favoured, partly no doubt as they are relatively close to where I live, but convenience was not all.  At this time few paths existed between many of this ranges hills and their northerly territory only had access via a courtesy path.  This was many years before the open access that we now enjoy today.  This partly forbidden territory only added to their appeal as a courtesy path can soon be turned in to investigation farther afield. 

This was many years ago, and now my walking is more contemplative and having visited the higher hills of Wales so many times I now enjoy investigating other hills, many of which are much lower in height, but nonetheless still situated in beautiful landscape.  However, opportunity to visit the higher hills still occasionally takes place and today a route had been planned taking in Ffridd Cwm Ffynnon as a marginal non-Dewey and Braich yr Hwch as a P10 needing to be surveyed, between the two are Foel Hafod Fynydd, Esgeiriau Gwynion and Foel Rudd.  This circuit gave good bagging and surveying potential.  It also gave stunning views in to those higher Aran hills with the block of cliffs between Aran Fawddwy and Aran Benllyn only broken by the steep grassed slope leading to Erw y Ddafad Ddu. 

The high Aran

I met Aled in the Llanuwchllyn car park and he then drove further up valley to our designated parking place, with Mark later joining us on the hill.  From here we walked up Cwm Croes with me taking great delight pointing out all the potential parking places that we had disappointedly ignored! 

The forecast for the day was good with clear skies, but with a chilled easterly breeze.  After leaving the car the high Aran was already on grand display with their cliffs dominating above the foreground of green pastured grazing fields; a stunning sight to greet us as we set off on our walk.  As our meeting time was all too uncivilized for Mark, he was setting off an hour or so later and would meet us on the hill. 

Erw y Ddafad Ddu

The paved road up Cwm Croes ends at Nant-y-barcut farm, from here a good track continues toward the buildings of Cwm-ffynnon which are undergoing renovation.  A vehicle track on the moor then heads up toward Cwm Ddu with a path continuing to Bwlch Sirddyn where we would meet Mark in a few hours’ time.  We opted to follow the vehicle track toward the bottom of steep ground that led up Braich yr Hwch; the P10 that Aled wanted surveying. 

The steepness soon increased and my pace relented to a steady gasping plod.  However, to compensate the view opened up and what a view it was.  The cliffs of Erw y Ddafad Ddu are rarely seen than from this vantage point, whereas those of Aran Fawddwy and Aran Benllyn always stand out.  But this route gave us such a close view in to the steep rising ground up to the main Aran ridge. 

The cliffs of Erw y Ddafad Ddu

The track on the moor that we followed turned out to be made by a quad bike and this kept to the rising ground as it tapered in to a narrow steep ridge, not a place that I would favour riding such a thing, a skilled hand would be needed to negotiate safe passage. 

Heading toward the steepening slopes of Braich yr Hwch

Eventually I crested the upper ridge and Aled was standing on the high point of Braich yr Hwch.  I soon set the Trimble up to gather its allotted data.  Once the equipment was closed down and packed away we headed down to the hill’s connecting bwlch where we spent a few minutes assessing the lay of land before choosing placement for the Trimble.

As I sat scribbling all necessary details in my survey notebook, Aled called over as he had spotted Mark walking up the valley.  Once bwlch data were gathered and stored we made our way up continuing steep ground toward the summit of Foel Hafod Fynydd.  Thankfully the steepness relented toward the upper part of the hill, but I still needed to gather my breath once at the summit.

The high point of Foel Hafod Fynydd is positioned a few metres from its cairn and soon the Trimble was placed on Aled’s rucksack with its internal antenna aligned with the high point of the hill and once the 0.1m accuracy level was attained before data should be logged, I set it to gather data and joined Aled sitting below the equipment and out of the brisk breeze. 

Gathering data at the summit of Foel Hafod Fynydd

The next point to survey was the bwlch connecting Foel Hafod Fynydd with Esgeiriau Gwynion.  To get to it involved losing a lot of height on very steep ground.  As we contoured around the upper part of the hill I spotted a figure sheltering behind a peat hag down at the bwlch; it was Mark.  Arriving at the bwlch it was good to see him.  He had spotted us making progress toward the summit of Foel Hafod Fynydd and had been waiting at the bwlch for about 45 minutes. 

Descending steep ground toward Bwlch Sirddyn

For some perverse reason I had always wanted to survey this bwlch.  I think this is due to contrasting contour information on contemporary Ordnance Survey and Harvey Maps as well as the old 5m contouring that was available on the OS Maps website.  Prior to this survey this bwlch was listed with an estimated c 500m height and now it was time to put an accurate height to it. 

Erw y Ddafad Ddu and Aran Benllyn from Bwlch Sirddyn

We each gave an opinion toward the position of the bwlch and agreed that it was ground beside the fence that crosses the land on the hill to hill direction.  The Trimble was soon positioned on one of the fence posts and gathering data. 

Gathering data at the bwlch of Esgeiriau Gwynion

During data collection I sat with Mark and Aled out of the breeze behind a peat hag listening to their conversation whilst enjoying a sandwich, all seemed good in the world!  I left the Trimble to collect 10 minutes of data before closing it down, packing it away and then looking up at the steep rising ground ahead.  This led to the summit of Esgeiriau Gwynion and as I ever so slowly plodded up the slope and emerged near the top of this horrendous slope, I looked at Mark and said that ascending it was like being tortured by the Spanish inquisition. 

Steep ground leading up toward the summit of Esgeiriau Gwynion

Mark is close to the high point of Esgeiriau Gwynion as surveyed by the Trimble GeoXH 6000

Two points were surveyed for summit position of Esgeiriau Gwynion.  The first which many believe to be the high point is beside a small cairn of quartz rocks which has a discarded old fence post stuck in the middle of it.  The second point was beside the ridge path adjacent to a fence that we had followed to make our way to the cairn, whilst doing so we all commented that we thought ground beside this fence higher than that beside the small cairn.  We’ll have to wait for the Trimble data to be processed before this question is answered. 

The first of two positions surveyed for the summit of Esgeiriau Gwynion

These two surveys also gave me time to sit and rest and soak in that ever present and wonderful view.  The breeze still blew, but the chill of early morning was being quickly replaced by an afternoon warmth, all too welcome on the higher hills. 

The second of two positions surveyed for the summit of Esgeiriau Gwynion

We had two further hills to visit and survey, but thankfully the majority of the uphill was now behind us.  Leaving the summit area of Esgeiriau Gwynion lay large peat hags, all dry and all looking other worldly with their parched moor grass not yet summer greened.  Beyond these lay a descending moor leading down to the connecting bwlch with Foel Rudd. 

Heading toward Foel Rudd

Although relatively expansive the position of the critical bwlch of Foel Rudd was not difficult to pinpoint.  With direction from Mark and Aled I headed toward where we considered it lay, whilst doing so I walked up a part of the southerly valley following a narrow channel which led me to where I then placed the Trimble. 

Gathering data at the bwlch of Foel Rudd

Once the allotted bwlch data for Foel Rudd was gathered and stored we followed a narrow path up to the hill’s summit.  We all agreed that the high point was amongst heather approximately 2 metres from the small quartz cairn and fence post that adorns the hill. 

Gathering data at the summit of Foel Rudd

Just one hill remained; Ffridd Cwm Ffynnon, which is positioned on the northerly descending ridge from Esgeiriau Gwynion.  I had visited this hill once before in May 2002 with Bill Owens who had helped me with a basic levelling survey of the hill. 

We started to descend from the bwlch connecting with Foel Rudd, with the ground soon turning in to the roughest experienced during the day.  The rough stuff mainly consisted of reed grass and some bog, it was never difficult but toward the end of many hours on the hill it sapped my already depleting stores of energy. 

The last hill of the day; Ffridd Cwm Ffynnon

A raised embankment crosses the bwlch of Ffridd Cwm Ffynnon and heads toward and beyond its summit.  This is an old field or ffridd boundary and is now grassed over with just an occasional quartz rock protruding from its side.  We debated where to gather data from at the bwlch, having all decided that the embankment was obviously man-made and therefore should be discounted from being taken as a part of either the bwlch or summit height of the hill. 

Having decided upon a suitable position for the bwlch, I placed the Trimble on top of a fence post and with Mark’s help measured the offset between its internal antenna and the ground at its base and then waited for the allotted data to be gathered and stored. 

Gathering data at the bwlch of Ffridd Cwm Ffynnon

A narrow path beside the embankment led us to the summit of Ffridd Cwm Ffynnon and an Abney level was then used to determine on which side of the embankment and adjoining fence the highest remaining natural ground lay.  Once determined, the Trimble was soon set up gathering its tenth and last data set of the day. 

Gathering data at the summit of Ffridd Cwm Ffynnon

All that now remained was to re-trace our route back to the connecting bwlch and follow a track down in to the upper reaches of Cwm Ffynnon.  It was a beautiful route down with the high Aran now no more than blued silhouettes with the afternoon sun hiding their morning’s detail.

Descending in to the bowl of the cwm meant that the breeze also now left us and it soon warmed proceedings with the afternoon sun increasing in strength.  It was also a relatively long walk out, back past Nant-y-barcut farm and down the paved lane.

Time to rest and enjoy the sunshine

I stopped occasionally to take in the scene and also take a few photos with chickens and lambs highlighted by rich afternoon colour.  It had been another good day on the hill, my third consecutive day which is a rarity for me nowadays.  I arrived back at the awaiting cars a few minutes after Mark and Aled and proceeded to bask in the luxury of getting my walking boots off.  A simple pleasure desperately needed!

Mapping Mountains – Trimble Surveys – Y Berwyn

 

02.04.21  Garth Goch (SH 952 357) and Garth Rhiwaedog (SH 950 349)

The brackened slopes of Garth Goch (SH 952 357)

Having visited and surveyed the hills around and including Y Garnedd (SH 741 431) with Aled earlier in the day and with the weather set fine, albeit with a chilled easterly wind, I wanted a small walk and survey on the way home and combining Garth Goch with Garth Rhiwaedog was ideal. 

I’d previously visited these two hills but had not surveyed them, but each had been LIDARed prior to this walk.  I remember Garth Goch had an impressive boulder on its summit, but otherwise and without reading the notes from my bagging journals, I have little memory of either hill.

LIDAR image of Garth Rhiwaedog (SH 950 349)

The conditions on top of Y Garnedd were gloriously sunny but the east wind chilled proceedings; I hoped that as these two hills are significantly lower in height that the continuing wind wouldn’t have such an impact. 

I parked between the two hills, just off of the B4391 road as it makes its way from Y Bala over the Y Berwyn.  A path through bracken led up Garth Goch past yellow gorse bushes that vividly sparkled in the sunlight.  The path led all the way to the impressive boulder at the summit of the hill. 

Whilst on the hills leading to Y Garnedd I carried three small rocks in my pockets to position against the Trimble and keep it wedged in place against the wind whilst gathering data.  After getting to the top of the boulder at the summit of Garth Goch I descended and then assessed the boulder and picked the very highest bit of summit rock to align with the Trimble’s internal antenna.  Once the equipment was aligned with the high point of the boulder I placed the three rocks against the sides of the Trimble, wedging it in place and making it stable. 

Gathering data at the summit of Garth Goch

Once the 0.1m accuracy level was attained before data should be logged, I set it to gather data, scrambled back down the boulder and enjoyed the sunshine, blue skies and view.  Garth Goch is a fine small hill, easily past when driving toward Y Bala, but its shape is attractive, and with brackened slopes, good paths and coloured gorse bushes a visit to its summit makes a good small outing.

Once the allotted data were gathered and stored I closed the equipment down, packed it away and headed down in a different direction toward another large boulder where a plaque proclaims that the first recorded sheep dog trial took place on this site and the field opposite in October 1873.  I remember walking up the path leading to this rock with my father many years ago; he was of an age that he could only look at it from a distance and not manage the last steepening bit of grassed path that leads directly up to it.  This memory brought me a contented feeling from days that are now long gone. 

The plaque on the boulder

The site of the first recorded sheep dog trial

The greened path from this boulder led down to the B road, from where it was only a short walk to the paved access lane that leads to Ty’n-y-coed farm.  The lane is designated a public footpath as is the continuation through an adjacent field which then gave me access toward the upper part of the second hill of this walk; Garth Rhiwaedog.  This hill shone greened with pasture against the early April sun when I was on Garth Goch.  Its slopes were dotted with sheep and whitened lambs in tow.  These were scattered amongst an attractive copse of mature trees.  Not yet in bud the trees reached skyward skeleton like with their branches forming a myriad of ever diverging patterns. 

Garth Rhiwaedog (SH 950 349)

I slowly gained height toward the summit of Garth Rhiwaedog, overheating on the way.  The lane leading to the field and the trees gave shelter from the easterly breeze and I’d considered converting my walking trousers to shorts, but as height was gained and any semblance of shelter lost, I was again glad that I was wrapped up against the elements. 

Gathering data at the summit of Garth Rhiwaedog

The summit of Garth Rhiwaedog consists of a slight raised grassy knoll with a small circular flattened stony patch where sheep lick was set in a bucket.  The Trimble was soon set up gathering data and whilst it did its stuff I sat on a rock and looked out toward the high Arenig, their pointed summits blued grey in the afternoon light. 

Arenig Fawr from the summit of Garth Rhiwaedog

Once the allotted data were gathered and stored and the equipment closed down and packed away I retraced most of my inward route back to my car, only diverging to use a different gate high on the hill.  During my descent lambs scattered across the field, all except for one, by now I had stopped as I did not want to scare either a mother or a lamb from each other.  During this one of the lambs walked straight up to me and nuzzled my leg, no doubt it was used to human company.  It stayed there for a minute or so before scampering off. 

It had proven another good day on the hill with two walks completed, six hills surveyed, resulting in a lot of data to now process.

Mapping Mountains – Trimble Surveys – Y Berwyn

 

16.03.21  Cae Bonc (SJ 129 121), Bryn y Fedwen (SJ 115 125), Pen y Garth (SJ 121 135), Cefn Dreiniog (SJ 145 147) and Gallt yr Ancr (SJ 145 130)

Foel Fawr (SJ 130 146) and Cefn Dreiniog (SJ 145 147)

Before leaving home I accessed the Meteoradar website and watched a rain band progressing from the north-west of Wales south-eastward toward Welshpool and the hills I planned on visiting.  As the rain band crept south-eastward it steadily decreased in intensity.  I looked outside and although rain had recently fallen and the sky was heavy with grey, it was not then raining.  I loaded my car with walking boots and rucksack, quickly checked my lap top and saw the rain band dissipate and headed toward Meifod driving approximately five miles that the recently altered restriction to Stay Local permits. 

Outside of a small Christmas day walk with my brother this was the first time since 12th December last year that I had driven to a start of a hill walk.  It was oddly refreshing to do this, even if restricted to just five miles.  I felt as if the world had suddenly opened up with the possibilities almost endless beyond those of Yr Allt, Y Golfa and the canal tow path. 

Prior to this walk I’d looked over maps and analysed LIDAR and had come prepared with five summit grid references that would take me on a good circular walk from Meifod over two small hills to Pontrobert, before continuing across two higher hills and ending on the summit of Gallt yr Ancr; an impressive looking hill positioned directly above the small community of Meifod. 

LIDAR image of Bryn y Fedwen (SJ 115 125)

Having found a convenient place to leave my car I was walking by 8.35am on the continuation of a narrow country lane heading west toward the first hill of the day; which the Tithe names its upper bounded field as Cae Bonc.  The lane was wet with patches of mud as were the near fields, the overnight rain had made field walking decidedly sloshy but I was soon above Coed-cowrhyd farm with the Trimble placed on a fence post above the summit of the hill. 

Gathering data at the summit of Cae Bonc

As the Trimble gathered its customary summit data a small flock of sheep gazed my way between their mornings munching.  Back to my east Gallt yr Ancr looked impressively dominant rising above pastured green fields. 

Gallt yr Ancr (SJ 145 130)

Before leaving the summit of Cae Bonc I took a compass reading toward the next hill and then headed down toward a wooden fence and gate.  All was quiet as I made my way back down the hill, the sky was still grey, although patches of whiteness were emerging toward the north-west, this was the first sign of the beautiful conditions later in the day that would quickly emerge across the land, but for now I was content with muddied tracks and the intricate weaving of public footpaths across a myriad of grazing fields. 

Cae Bonc (SJ 129 121)

Over the last few weeks I’d become accustomed to Linda’s company during walks and enjoyed it immensely, today I was on my own and appreciated the solitude and quiet surrounds.  I’d occasionally stop and listen, there was little to intrigue one’s imagination, just distant bird song brought on the breeze, the slight hum of a farm vehicle somewhere off in the distance, the trickle of water as I forded a brook and the ever present sound of my breathing as I slowly gained height toward the top of my second hill of the day; Bryn y Fedwen. 

Gathering data at the summit of Bryn y Fedwen

The name of Bryn y Fedwen was again derived from the Tithe map and its highest point was beside a hedge in a nondescript field, one like many others, where silence predominated.  After data collection I retraced my steps back to a muddied track leading to an old farm house and stopped and chatted with the couple who lived there.  They were out walking their dog, which flew in excited circles roaring around the adjacent field.  They mentioned how unusual it was to talk to another person; the times of Covid have indeed been most unusual. 

Following a lane down in to the confines of Pontrobert I then steadily gained height on a minor road before turning right on a track leading to Garth Fawr.  This track would give me access to a steep field on my left which would take me to the summit of my third hill of the day; Pen y Garth. 

Pontrobert

I slowly gained height up the field, occasionally zig-zagging to lessen the immediate gradient.  As height was gained the view opened up and by the time I arrived at the summit blue sky dominated with spring freshness and warmth only dreamt of during the winter months. 

The high point of Pen y Garth was easy to pinpoint and within a couple of minutes the Trimble was set up gathering its allotted data.  During data collection I stood and looked out across what to me was a stunning landscape of coloured fields, rising hills, distant mountains and succulent blue sky.  These hills will never disappoint and this part of Wales, like so many others, will always give a sense of openness and a feeling of welcome. 

Gathering data at the summit of Pen y Garth

I celebrated my enthusiastic state of mind by eating a sandwich and once the Trimble had done its stuff and was packed away I headed down toward a narrow lane and the track leading to Pen-y-bryn.  From here public footpaths led across forgotten and quiet fields, through gates next to dappled brooks where the sunshine, bird song and that all welcoming warmth made me linger, sit and again just listen, it was a beautiful time with little happening, which made it all the more special. 

The distant Breiddin from the summit of Pen y Garth

The public footpath led me to an option of two gates with a wooded area in front.  I didn’t want to get immersed in pathless woodland and so headed toward a small house that was still on a trailer to ask directions.  The first person I met was a young boy who enthusiastically told me about his white t-shirt, I asked if his Mum or Dad were in, he said his Mum was.  When his Mum emerged we happily chatted away for five minutes or so, she told me the house would eventually be moved to the top of the adjacent field, along with her partner they had moved there from Llanfair and when pregnant with her proudly white t-shirted son they had travelled around continental Europe with their two other children in a camper home.  By now the sun seemed as if it was ablaze, I was kitted out more for a winter walk and was over-heating.  To stop and talk and make contact with a fellow human was an unexpected treat.  When I explained my onward route she kindly directed me toward a stile and the continuing path through the wood that would emerge on to a filed.  I thanked her and waved my goodbyes. 

Beyond the wood and the field another stile led on to another quiet country lane, my next hill rose above to the east, it looked rather stunning in the spring sunshine but with wooded areas and no discernible path I wondered if I may be bracken bashing up its steepening slopes. 

Whilst on the lane I headed toward a gate to get a better view of any onward route, there circling the slope below the lane was a green track disappearing around a corner which would at least take me down to the green pastored valley bottom and lead me toward the ascent of the hill. 

I found the start of the green track a little further up the lane and wandered down its initial muddied way before it turned into drier conditions which proved a delight.  I only remained on the track for a short distance as it continued away from the hill; therefore I wandered down steeply to join the flat bedded land between it and the rising slopes ahead.  Sheep cascaded across the flat pastured field in front, bleating as they did so, no doubt surprised to be confronted by an overdressed hill walker. 

The old green track leading toward Cefn Dreiniog

Once off the green track I sat on the steepened slope and watched nothing, just sheep and their whitened lambs moving toward and then past me.  It was warm for the time of year and I felt uncomfortably overdressed, therefore I happily spelt ten minutes taking my boots off and converting my walking trousers to shorts and felt instantly better for doing so. 

A vehicle track on the pastured field led the way toward a gate, where it continued toward another gate, this gave access in to the wood.  Once in the wood I followed rising ground close to its boundary fence and soon came across what looked like a disused track, this gave easy and pleasant walking and swung around gaining height and proved an ideal way up the hill without any off path bracken bashing.  Toward the end of the wooded section I again sat on a fallen bow in the sunshine and looked up at the trees heading skyward to an almost iridescent blue sky above.  This was proving a very enjoyable walk and except for an occasional unexpected meeting with a fellow human being it was just so quiet with only nature’s ever present tune playing in the background.  Whilst sitting on the fallen bow I listened to the staccato drilling of a near woodpecker, breeze-blown birdsong that when I stopped was ever present and an occasional bleat of a mother sheep and accompanying lamb.  I sometimes find it hard to write about such moments, but when I close my eyes the memories take me back to those translucent sounds as they meander across my mindscape. 

The view above from my rest spot

Eventually I moved from the fallen bow and continued ever up hill, only stopping once I reached the summit of Cefn Dreiniog, which is free of trees and positioned on one of a number of grassed bumps that make up the broad summit ridge of this hill.  I again found another bow to sit on as the Trimble gathered its allotted summit data. 

Gathering data at the summit of Cefn Dreiniog

My onward route was down toward the old house of Ywen, before leaving the summit I took a compass bearing to direct me and then followed a fence steeply down to a gate which gave access back in to a wood.  Sunlight dappled across dead and crisped fallen leafs as I made good progress downhill.  Woods can bring a pleasure all their own, and this one was no exception; the dappled light, solitude and surrounds were to be savoured. 

I emerged out of the wood and followed a narrow paved access lane down to the paved country lane which headed confidently southward toward Meifod.  I was nearing the end of my walk, but one hill still remained; Gallt yr Ancr.  Although not the highest on the day’s outing, it was one of the most impressive.  This hill rises steeply and directly above the small community of Meifod.  I’d only been to its summit once before ascending via a public footpath from the lane to the north, today I wanted to traverse the hill using the eastern ridge as my ascent route.  I’d read online logs mentioning a series of steep steps and a ridge path through the wooded part of the hill.  This sounded very different to anything I’d encountered during the day and I was looking forward to it. 

Beautiful place to live

Rounding the corner of the lane Gallt yr Ancr shot skyward, it looked dauntingly steep to a tired body and mind.  But I knew that with many rests and steps to sit on I could take my time and follow the old mantra of just putting one foot in front of the other and bit by bit progress can be made. 

As I entered the confines of Meifod I checked on directions to the steps and was soon hunched double panting trying forlornly to re-gain my breath.  The steps were steep, I had to stop and sit and try and discover some semblance of normalcy.  Thankfully two people were trimming back bracken on the steep land adjacent to the steps and once I stopped, sat and re-claimed my composure we chatted away for about ten minutes.  They were brother and sister; he lived in Pontrobert, she just below where we were.  They were hoping to create a path through the undergrowth.  I was more than happy just to sit and talk, the steps were in shade and this gave solace.  However, eventually I stood up, and continued up hill. 

The steep steps leading up Gallt yr Ancr

The path leading up the eastern ridge of Gallt yr Ancr is a delight.  Initially it follows steep steps with a handrail and a single small bench for those like me who appreciate such things on steepening ground.  The path continues traversing the ridge through conifers, I’d seldom come across such a path in Wales.  It reminded me of traversing Pico Turquino in Cuba where only an occasional glimpse of a view was had.  Gallt yr Ancr is about 5,500ft lower, but nonetheless this path gives a stunning little route to its summit. 

Today the summit of Gallt yr Ancr was bathed in the most delightful and welcome afternoon sunshine, where blue skies sped across the horizon.  In the distance pastured fields merged with hill tops, these joined valley bottoms before more ridges and hills disappeared in to the distance.  It was uplifting being on this summit.  It floated above the valley with the houses of Meifod nestled in the depths. 

Gathering data at the summit of Gallt yr Ancr

As the Trimble gathered summit data, I again sat.  Soon it was time to leave, but not before taking one last look from the edge of the summit area to the forestry below and the beginning of the steep path leading down its eastern ridge.  I lingered for a few moments savouring the scene before turning and heading down the hill’s westerly slopes.

The descent west is in contrast to the eastern ascent route.  It is open and follows a good path down steep green slopes before joining what looks like a relatively new gravelled access track, this brought me down to a gate and the narrow lane where my car was parked.  The walk had taken over 7 hours with five summits surveyed.  Once back at my car I luxuriated in getting my walking boots off.  I changed and enjoyed the feeling of warmth on my body.  It was only a short drive back home where a bowl of soup and a hot bath awaited.

LIDAR – Postscript 

Since visiting these hills full LIDAR coverage is now available.  The LIDAR (Light Detection & Ranging) technique produced highly accurate height and positional data that is now freely available for England and Wales.  Consequently the numerical details for these hills have been analysed using this technique, resulting in the LIDAR height and position being used for some of these hills.
