Mapping Mountains – Significant Name Changes – Y Trichant – The 300m Hills of Wales and Y Trechol - The Dominant Hills of Wales


Foel Las (SH 894 687)

There has been a Significant Name Change to a hill that is listed in the Y Trichant – The 300m Hills of Wales and Y Trechol – The Dominant Hills of Wales, with the summit height, bwlch height and their locations, the drop, dominance and status of the hill confirmed by a Trimble GeoXH 6000 survey conducted by Myrddyn Phillips on the 5th April 2016, and latterly substantiated by LIDAR analysis.

Foel Las (SH 894 687)

The criteria for the two listings that this name change applies to are:

Y Trichant – The 300m Hills of Wales – Welsh hills at or above 300m and below 400m in height that have 30m minimum drop, with an accompanying sub list entitled the Sub-Trichant with the criteria for this sub category being all Welsh hills at or above 300m and below 400m in height with 20m or more and below 30m of drop.  The list is authored by Myrddyn Phillips, with the Introduction to the list and the renaming of it appearing on Mapping Mountains on the 13th May 2017.

Y Trechol - The Dominant Hills of Wales - Welsh P30 hills whose prominence  equal or exceed half that of their absolute height.  With the criteria for Lesser Dominant status being those additional Welsh P30 hills whose prominence is between one third and half that of their absolute height, with the Introduction to the Mapping Mountains publication of this list appearing on the 3rd December 2015, and which is now available in its entirety on Mapping Mountains in Google Doc format.

The hill is adjoined to the Mynydd Hiraethog group of hills, which are situated in the central northern part of North Wales (Region A, Sub-Region A2), and it is positioned with the A548 road and the Afon Elwy to its north and west, the B5382 road to its south and a minor road to its east, and has the small community of Llangernyw to the south-west and Llanfair Talhaiarn towards the east north-east.

The hill appeared in the original Welsh 300m P30 list on Geoff Crowder’s v-g.me website under the name of Tre-pys-llygod, which is a prominent name that appears close to the summit of this hill on contemporary Ordnance Survey maps.

During my early hill listing I paid little regard to name placement on the map, or the meaning of names and to what feature the name was appropriately applied to.  Therefore I prioritised names for listing purposes that I now understand are either inappropriate or where another name is viewed as being more appropriate.

As a variety of Ordnance Survey maps place the name Tre Pys Llygod applicable to the land mass taking in this and its adjacent lower westerly hill, I wanted to follow the history of this hill’s recorded name to see if another was more appropriate.

As the summit of this hill comprises bounded land the details for it were examined on the Tithe map.  The term Tithe map is generally given to a map of a Welsh or English parish or township and which was prepared after the 1836 Tithe Commutation Act.  This act allowed tithes to be paid in cash rather than goods.  The Tithe maps gave names of owners and occupiers of land in each parish and importantly for place-name research they also included the name of enclosed land.  This enclosed land is usually based on a field system, however not every field is given a name, but many are and especially so in Wales.

Extract from the Tithe map

The enclosed land where the summit of this hill is situated is given the number 633 on the 1842 Tithe map, this can be cross referenced against the apportionments; it is these apportionments that give the name of the owner or occupier of the land as well as the name of the land.  The land where the summit of this hill is situated is named as Ffridd foelas in the apportionments, with the details on the Tithe map appearing in the parish of Llanfair Talhaiarn in the county named as Denbigh.

Extract from the apportionments

Since publication of these P30 lists on Geoff Crowder’s v-g.me website there have been a number of Ordnance Survey maps made available online, some of these are historic such as the series of Six-Inch maps on the National Library of Scotland website, whilst others are current and digitally updated such as the Vector Map Local hosted on the Geograph website and which is entitled the Interactive Coverage Map.  One of the historic maps now available is the Ordnance Survey Draft Surveyors map which formed the basis for the first publicly available Ordnance Survey One-Inch ‘Old Series’ map, and it is the Draft Surveyors map that I next examined.

The Draft Surveyors maps consist of the preliminary drawings made by the Ordnance Surveyor’s surveyors between the 1780s and 1840 and formed the basis for the first publicly available One-Inch map.  They were drawn at scales of six inches to the mile for areas considered of particular military significance and down to two inches to the mile for other areas.  Fair copies were then produced from these preliminary drawings to one inch to the mile and then copper plates were prepared for printing.  The Draft Surveyors maps for the whole of Wales are now available online and they form an important part in the study of Welsh upland place-names as they bridge the time frame between the late 18th century and the mid-19th century when the Ordnance Survey produced their first One-Inch maps, and importantly for this hill and its listed name, this map records the name for this and its lower westerly hill as Y Foelas.

Extract from the Ordnance Survey Draft Surveyors map

The next map to examine was the One-Inch ‘Old Series,’ this was the first map that Ordnance Survey published, and they were based on the proceeding Draft Surveyors map.  Their publication culminated from the whole of Britain being surveyed between 1791 and 1874 and the detail gathered therein produced at a scale of one inch to the mile and published in sheet format between 1805 and 1874.  The One-Inch ‘Old Series’ maps for the whole of Wales are now available online; they are also available in map format as enlarged and re-projected versions to match the scale and dimensions of the Ordnance Survey 1:50,000 Landranger series and are published by Cassini.  This series of maps forms another important part in the study of Welsh upland place-names and bridge the time frame leading to the production of the Ordnance Survey base map of the Six-Inch series.  It is this map that first places the name of Tre-pys-llygod against these hills, with the name of Y Foel las also placed adjacent to the lower westerly hill.

Finally the series of Ordnance Survey Six-Inch maps were examined and the name of Tre-pŷs-llygod is recorded in large letters, with the name of Foel-lâs being recorded adjacent to the westerly of the two hills next to what looks like a small-holding.

Extract from the series of Ordnance Survey Six-Inch maps

The detail on the Six-Inch map and the use of the term Ffridd on the Tithe map implies that the small-holding existed and it was named Foel Las and the enclosed land taking in the summits of these two hills was a part of their ffridd and this was known as Ffridd Foel Las, with the name of Tre Pys Llygod being a later addition.

Therefore, the name this hill is now listed by in the Y Trichant is Foel Las, and this was derived from a number of sources including the Tithe map, Ordnance Survey Draft Surveyors map, Ordnance Survey One-Inch ‘Old Series’ map and the Ordnance Survey series of Six-Inch maps.

Mapping Mountains – Significant Name Changes – Y Trichant


Foel Las (SH 886 686)

There has been a Significant Name Change to a hill that is listed in the Y Trichant, with the summit height, bwlch height and their locations, the drop and status of the hill confirmed by a Trimble GeoXH 6000 survey conducted by Myrddyn Phillips on the 5th April 2016, and latterly substantiated by LIDAR analysis.

The hill appeared in the original Welsh 300m P30 list on Geoff Crowder’s v-g.me website under the directional name of Tre-pys-llygod West Top, with an accompanying note stating; Name from hill to the East.

Name from hill to the East


During my early hill listing I thought it appropriate to either invent a name for a hill, or use a name that appeared near to the summit of the hill on Ordnance Survey maps of the day.  My preference was to use farm names and put Pen, Bryn or Moel in front of them or as in this instance use a directional name based on supplanting the name adjoined to the hill to the east and adding a directional component to it.  This is not a practice that I now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historic documents, through this form of research an appropriate name for the hill can usually be found.

As a variety of Ordnance Survey maps place the name Tre Pys Llygod applicable to the land mass taking in this and its adjacent higher easterly hill, I wanted to follow the history of this hill’s recorded name to see if another was more appropriate.

Mapping Mountains – Trimble Surveys – Mynydd Hiraethog


05.04.16  Foel Las (SH 886 686) and Foel Las (SH 894 687)  

Foel Las (SH 894 687)

As the next installment of the Dominants is to the range of hills of Mynydd Hiraethog I wanted an appropriate photograph of Foel Las to accompany the introduction to this group of hills, therefore with the weather set fine I headed to north-west Wales. 

LIDAR image of the two Foel Las summits at SH 886 686 and SH 894 687

I left my car parked on the B 5832 close to a converted Chapel at SH 889 669 and headed toward a track where the critical bwlch for the higher of the two Foel Las summits is positioned.  The forecast for the day was good with mainly dry conditions with sunshine in the morning and build-up of cloud in the afternoon.

After assessing the lay of land on and around the track I positioned the Trimble on top of my rucksack and waited for the 0.1m accuracy level to be attained before pressing Log.  As data were gathered I stood an adequate distance away from the equipment and examined the map before looking up at the higher of the two hills I planned on visiting.  Between the two hills was forestry which wasn’t marked on the Explorer map I have, and having previously looked at online mapping there were also a number of small lakes now situated around the area of the bwlch between the two hills; there had obviously been a lot of work done in transforming the land around these hills with a number of tracks also indicated on online mapping leading to the small lakes.

Gathering data at the bwlch of the higher of the Foel Las summits

Once data were stored I packed the Trimble away and walked back to the road, past my car and up a minor lane toward a public footpath, I followed this, or at least I thought I had, until branching out over a number of fields aiming for a track which headed toward the summit of the lower of the two hills.  In hindsight I should have continued on the minor road for another 100 metres which would have given me direct access to a track which headed straight for the summit of my first hill.

As I walked over a field toward the track a vehicle pulled up, I headed toward it and spoke with the driver, I asked if she minded me using the track to visit the hills, she explained that she wasn’t the land owner and had been invited there for the day.  We chatted about the development on the hill, including the forestry.  I left having thanked her and she smiled back at me as I waved my good byes and continued up the track.

As I gained height a chilling breeze blew and I put my thin £5.00 gloves on which kept my fingers functional.  Off in the distance was the sound of a tractor which came in to view as I rounded a corner of the track, it was above the forestry moving back and forth high on the hill, also now in view were a number of small lakes, each positioned hugging the landscape and blending in to the environment.

The track I followed continued away from the lower Foel Las summit so I squelched my way across a wet field and headed up to where the tractor had been busy doing what tractors do.  By the time I came across its tracks it had moved on to another part of the hill which left the summit area quiet except for scampering lambs which suckled their mothers.  The high point was easily identifiable and soon the Trimble was aligned with it and gathering its customary five minutes of data.

The higher of the two Foel Las summits (SH 894 687)

Heading east from the summit toward the higher hill I walked down to the connecting bwlch which now has a small forestry plantation on it, this can be easily bi-passed on its northern side, as I headed that way I noticed a gate close to the edge of the higher of two lakes, this gave access to a track which cuts through beside the trees and which seemed to form the critical bwlch for the lower Foel Las summit.  Deciding to leave this bwlch survey until later I headed up to the higher summit.

The summit comprises a number of bumps, many positioned on small outcrops of rock.  I decided to survey three points, two of these points being a few metres from one another and which were positioned on the same bump, whilst the third was about 40 metres away and close to where the 320m ring contour appears on Ordnance Survey maps.  As these data sets were gathered I looked west toward the high Eryri peaks and watched as the cloud slowly ripped itself away from their ridges.

Gathering data at the higher summit

Just one survey remained on this first walk of the day and that was back at the connecting bwlch between the two hills.  I left the higher summit and wandered back to the track beside the small plantation of conifers.  Finding its low point on the valley to valley traverse proved relatively easy and I positioned the Trimble on top of my rucksack having measured a 0.41m offset between its internal antenna and the ground below.

As the Trimble’s accuracy level slowly ebbed down to 0.1m I waited beside the gate and let my mind wander to all manner of things.  Every five minutes I scampered back to the equipment to check on its downward accuracy progress, it took over fifteen minutes for the 0.1m accuracy level to be attained and once it had I quickly pressed Log and headed back to the gate for another five minute wait.

Once data were gathered and the equipment packed away I investigated the lay of land inside the forest and to its north, it was hard to judge where the exact bwlch lay as the tree coverage was not ideal for such a thing, but the ground looked as if it was constantly rising toward where the track is positioned.  Happy that I’d done all I could I headed toward a near track which connected with my inward route and which I followed down to the minor lane and my car.
