Mapping Mountains – Significant Name Changes – Y Trichant



Ffridd Nant y Gwyrddail (SH 674 147)

There has been a Significant Name Change to a hill that is listed in the Y Trichant, with the criteria for the list that this name change applies to are:

Y Trichant – Welsh hills at and above 300m and below 400m in height that have 30m minimum drop, with an accompanying sub category entitled the Sub-Trichant consisting of all Welsh hills at and above 300m and below 400m in height that have 20m or more and below 30m of drop.  The list is authored by Myrddyn Phillips and the Introduction to the list and the re-naming and publication history was published on Mapping Mountains on the 13th May 2017.

The hill is adjoined to the Cadair Idris range of hills which are situated in the south-western part of North Wales (Region A, Sub-Region A3), and it overlooks the double lakes of Llynnau Cregennan which are to its west south-west and is situated between the small community of Arthog to its west and the town of Dolgellau to its east north-east.

The hill appeared in the 200m P30 list on Geoff Crowder’s v-g.me website under the partly invented name of Bryn Nant-y-gwyrddail with an accompanying note stating; Name from buildings to the South-West.  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.  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now advocate as with time and inclination place-name data can be improved either by asking local people or by examining historical documents, through this form of research an appropriate name for the hill can usually be found, and as the summit of this hill comprises bounded land the details for it were examined on the Tithe map.

Name from buildings to the South-West


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 168 on the 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 Nantgwyrddeil [sic], with the details on the Tithe map appearing in the county named as Merioneth and in the parish of Dolgelley [sic].

Extract from the apportionments

The name given this bounded land relates to a farm named Nant-y-gwyrddail that is positioned at SH 671 143 and to the south-west of this hill’s summit.  Having visited a number of neighbouring hills and surveying the critical bwlch of this hill I then visited this farm and met Ceri Williams and her young son and daughter.  Ceri and her husband; Gwern, had moved here recently from the Garndolbenmaen area north-west of Porthmadog, she explained that the farm is tenanted from the National Trust and confirmed their boundary, which takes in the land where the summit of this hill is situated.  As Ceri is a newcomer to this area she suggested I should visit Emyr Rees who farms from Tynyceunant (SH 688 152).

As I pulled up in my car at the access track that leads to Tynyceunant, Emyr had just pulled up in his Landrover and was wielding a mighty mallet readying himself to work on a new fence post.  Emyr is aged 70 and has lived at Tynyceunant all his life and is a Welsh speaker.  After introducing myself and explaining my interest in upland place-names, we talked about the hills and their names.  Emyr told me that the land where the summit of this hill is situated is a part of Nant-y-gwyrddail and known as Ffridd Nant y Gwyrddail.  Emyr also gave me a number of other names for near hills, which will be detailed in later Significant Name Changes posts.

Therefore, the name this hill is now listed by in the Y Trichant is Ffridd Nant y Gwyrddail, and this name was derived from local enquiry, with the bounded land where the summit of the hill is situated confirmed by the Tithe map and substantiated with the present resident of the farm of Nant-y-gwyrddail.

Mapping Mountains – Trimble Surveys – Cadair Idris


17.02.18  Ffridd Nant y Gwyrddail (SH 674 147, only bwlch surveyed)

The bwlch of Ffridd Nant y Gwyrddail (bwlch at SH 662 134)

Having visited three hills close to where the critical bwlch of this hill lies I thought I should at least visit its boggy depths and obtain data, as this can be compared against the data that was gathered using a Leica GS15 when along with John Barnard and Graham Jackson we investigated this spot whilst surveying for the position of the critical bwlch of Pared y Cefn Hir (summit at SH 661 148).

It seems a long time ago when in November 2012 this bwlch was surveyed using the Leica equipment, as we had surveyed the summit of Pared y Cefn Hir and its adjacent hill of Bryn Brith, we needed to find the position of the bwlch connecting the higher of these two twin topped 383m map heighted hills to ascertain its drop value, and as the map indicated three positional possibilities for this critical bwlch, each in turn needed surveying, and the bog that makes up this potential bwlch position was by far the most soggy and unwelcome, to the point that after standing immersed in the bog operating the staff for about 45 minutes I thought I was suffering from trench foot!

Using level and staff in November 2012 to determine the bwlch position of Ffridd Nant y Gwyrddail

Today was an easy proposition in comparison as I had come prepared with the ten figure grid reference for this bwlch position.  When surveyed with the Leica GS15 this position proved not to be the critical bwlch of Pared y Cefn Hir (which proved by 0.09m to be the higher when compared to Bryn Brith), but it is still a connecting bwlch for another hill, and that hill is positioned down stream of this bwlch to its north-east with its summit given a map height of 312m at SH 674 147, the hill remains unnamed on the map but a visit to a local farmer after this survey gave the name of Ffridd Nant y Gwyrddail for the bounded land where the summit of this hill is situated.

It was only a couple of minutes’ drive from where my car was parked to where a passing place beside the minor road gave me an opportunity to leave the car for the short period of time this bwlch survey would take.

I was soon in the bog, thankfully wearing wellies this time, and used the Trimble as a hand-held device to zero in on the ten figure grid reference.  Even after doing this the underfoot conditions would still give a large margin of uncertainty to Trimble placement as tussock grass predominated. 

Gathering data at the critical bwlch of Ffridd Nant y Gwyrddail

As the Trimble ebbed down to the 0.1m accuracy level before data should be logged I watched as the delicate play of light slowly cast down upon adjacent hills, with the coned and pyramidal profile of Ffridd Bellau Nant y Gwyrddail looking particularly fine. 

Ffridd Bellau Nant y Gwyrddail (SH 665 139) on the left and Ffridd Nant y Gwyrddail (SH 674 147) on the right

Once the 0.1m accuracy level appeared I pressed ‘Log’ and waited for the allotted five minutes of data to be gathered.  My stay in the bog had been a short one, and especially so when compared to my last visit.  Once back at the car I drove the short distance down the valley and called at Nant-y-gwyrddail before visiting Emyr Rees of Tynyceunant.
