Mapping Mountains – Significant Name Changes – Y Pedwarau


Y Pedwarau – Significant Name Changes

Y Pedwarau are the Welsh hills at and above 400m and below 500m in height that have a minimum drop of 30m.  Accompanying the main P30 list are five sub lists; these are the 500m Sub-Pedwar, 500m Double Sub-Pedwar, 400m Sub-Pedwar, 390m Sub-Pedwar and 390m Double Sub-Pedwar category’s, with their criteria detailed in the respective Change Registers that have been created and which are linked in their above titles, with the Introduction to this list being published on Mapping Mountains on the 30th January 2017.

The list is co-authored by Myrddyn Phillips and Aled Williams and the posts that have appeared on Mapping Mountains detailing the significant name changes to hills in the main P30 list and the sub lists appear below presented chronologically in receding order.









Mapping Mountains - Significant Name Changes - Y Pedwarau

Top Nant Cwm Mawr (SJ 253 497) - 35th significant name change


There has been a Significant Name Change to a hill that is listed in the Y Pedwarau – The 400m Hills of Waleswith the summit height, bwlch height, the drop and status of the hill confirmed by spot height data and interpolation from the contemporary Ordnance Survey 1:25,000 Explorer map.

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

Y Pedwarau – The 400m Hills of Wales.  Welsh hills at or above 400m and below 500m in height with 30m minimum drop, the list is co-authored by Myrddyn Phillips and Aled Williams and is published on Mapping Mountains in Google Doc format.

The hill is adjoined to the Moel y Gamelin group of hills, which are situated in the north-eastern part of North Wales (Region A, Sub-Region A2), and it is positioned with the A525 road to its north-west, the B5430 road towards its north and the B5426 road to its east, and has the town of Wrecsam (Wrexham) towards the east.

The hill appeared in the original Welsh 400m P30 list on Geoff Crowder’s v-g.me website, under the name of Esclusham Mountain, which is a name that appears close to this hill’s summit on contemporary Ordnance Survey maps.

Extract from the Ordnance Survey 1:25,000 Explorer map

The name of Esclusham Mountain also appears online in the Welsh variant of Mynydd Esclus, as evidenced on the Ordnance Survey map on the WalkLakes website.  However, this rendition may be a modern rendering without historic merit or local usage.

Extract from the WalkLakes website

Ideally names on maps that can be viewed as being established should be substantiated by people who work the land that the summit of the hill is situated on, as preference for locally known names can change over time, and in the case of this hill it was a chance encounter with the  local gamekeeper who gave the name of Top Nant Cwm Mawr for this hill.

Therefore, the name this hill is now listed by in the Y Pedwarau – The 400m Hills of Wales is Top Nant Cwm Mawr, and this was derived from local enquiry.


The full details for the hill are:

Garwyd (SH 996 459) - 34th significant name change


There has been a Significant Name Change to a hill that is listed in the Y Pedwarau – The 400m Hills of Waleswith the summit height, bwlch height, the drop and status of the hill confirmed by spot height data on the contemporary Ordnance Survey 1:25,000 Explorer map.

Extract from the Ordnance Survey series of Six-Inch maps

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

Y Pedwarau – The 400m Hills of Wales.  Welsh hills at or above 400m and below 500m in height with 30m minimum drop, the list is co-authored by Myrddyn Phillips and Aled Williams and is published on Mapping Mountains in Google Doc format.

The hill is adjoined to the Mynydd Hiraethog group of hills, which are situated in the north-eastern part of North Wales (Region A, Sub-Region A2), and it is positioned with the A5 road and the Afon Ceirw to its south, and has the village of Cerrigydrudion towards the west north-west and the town of Corwen towards the east south-east.

The hill appeared in the original Welsh 400m P30 list on Geoff Crowder’s v-g.me website, under the name of Cader Dinmael, which is a name that appears close to this hill’s summit on contemporary Ordnance Survey maps.

The composition of the name was amended to Cadair Dinmael to reflect the use of standard modern Welsh, however hill list authors are prone to list a hill by the name that appears nearest to its summit on contemporary Ordnance Survey maps, without much consideration for its local or historic confirmation, or whether map placement is appropriate.

Extract from the Ordnance Survey 1:25,000 Explorer map

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, and in the case of this hill it is the series of Ordnance Survey Six-Inch maps that shows the name of Garwyd being prioritised over that of Cadair Dinmael for this hill.

Extract from the Ordnance Survey series of Six-Inch maps

Therefore, the name this hill is now listed by in the Y Pedwarau is Garwyd, and its prioritised status was derived from the Ordnance Survey series of Six-Inch maps.


The full details for the hill are:

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

Y Pedwarau – Welsh hills at or above 400m and below 500m in height that have 30m minimum drop.  The list is co-authored by Myrddyn Phillips and Aled Williams, with the Introduction to the Mapping Mountains publication of this list appearing on the 30th January 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.

The hill is adjoined to the Cymoedd Gwent group of hills which are situated in the eastern part of South Wales (Region C, Sub-Region C2), and it is positioned with the A4051 and A4042 roads to its east, the A472 road to its north and the A467 road to its south-west, and has the town of Pont-y-pŵl (Pontypool) towards the north-east. 

The hill appeared in the original Welsh 400m P30 list on Geoff Crowder’s v-g.me website, under the name of Mynydd Twyn-glas, which is a name that appears close to this hill’s summit on contemporary Ordnance Survey maps.

Hill list authors are prone to list a hill by the name that appears nearest to its summit on contemporary Ordnance Survey maps, without much consideration for its local or historical confirmation, or whether map placement is appropriate, and in the case of this hill the names of Mynydd Twyn-glas and Mynydd Maen have been consistently shown near the summit of this hill on different scaled Ordnance Survey maps.

Extract from the Ordnance Survey 1:50,000 Landranger map

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, and in the case of this hill it is the series of Ordnance Survey Six-Inch maps that shows the name of Mynydd Maen being prioritised over that of Mynydd Twyn-glas.

Extract from the Ordnance Survey series of Six-Inch maps

Therefore, the name this hill is now listed by in the Y Pedwarau and the Y Trechol – The Dominant Hills of Wales is Mynydd Maen, and its prioritised status was derived from the Ordnance Survey series of Six-Inch maps.

Mapping Mountains - Significant Name Changes - Y Pedwarau

Buddugre (SO 089 700) - 32nd significant name change

Survey post for Buddugre


There has been a Significant Name Change to a hill that is listed in the Y Pedwarauwith the summit height being confirmed by a Trimble GeoXH 6000 survey conducted by Myrddyn Phillips and which took place on the 10th July 2018, and the bwlch height confirmed by LIDAR analysis conducted by Aled Williams and subsequently by Myrddyn Phillips.

Buddugre (SO 089 700)

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

Y Pedwarau – Welsh hills at or above 400m and below 500m in height that have 30m minimum drop.  The list is co-authored by Myrddyn Phillips and Aled Williams, with the introduction to the Mapping Mountains publication of this list appearing on the 30th January 2017.

The hill is adjoined to the Pegwn Mawr range of hills which are situated in the north-eastern part of Mid and West Wales (Region B, Sub-Region B1), and it is positioned between the stream valleys of the Clywedog Brook to its west and the Afon Ieithon (River Ithon) to its east, and has the small community of Abaty Cwm-hir (Abbeycwmhir) towards the west north-west. 

The hill appeared in the original Welsh P30 lists under the 400m P30 height band on Geoff Crowder’s v-g.me website, under the name of Beddugre Hill, which is the name given the hill on contemporary Ordnance Survey maps.

Hill list authors are prone to list a hill by the name that appears nearest to its summit on contemporary Ordnance Survey maps, without much consideration for its local or historical confirmation, or whether map placement is appropriate, and in the case of this name the Hill part is a later addition as evidenced by detail on the Ordnance Survey Draft Surveyors map and the series of Ordnance Survey Six-Inch maps.

Extract from the Ordnance Survey 1:25,000 Explorer map

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 historical 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 Interactive Coverage Map hosted on the Geograph website.  Two of the historical maps now available are the Ordnance Survey Draft Surveyors map which formed the basis for the Ordnance Survey One-Inch ‘Old Series’ map.

Extract from the Ordnance Survey Draft Surveyors map

Extract from the Ordnance Survey series of Six-Inch maps

The Draft Surveyors maps consist of the preliminary drawings made by the Ordnance Survey’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.

The later edition of the word Hill is also tautological as Buddugre can be translated as victory hill.  The name Buddugre is the originator of the name that appears on contemporary Ordnance Survey maps; Beddugre Hill, which is a tautological anglicised version of the hill name. 

Therefore, the name this hill is now listed by in the Y Pedwarau is Buddugre, and this was derived from the originator name that is widely referenced online.

Bwlch Bank (SO 242 720) - 31st significant name change

Survey post for Bwlch Bank


There has been a Significant Name Change to a hill that is listed in the Y Pedwarau, with the height of the summit confirmed by a survey with the Trimble GeoXH 6000 which took place on the 19th April 2018, and the height of the bwlch ascertained from LIDAR analysis conducted by Aled Williams.

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

Y Pedwarau – Welsh hills at and above 400m and below 500m in height that have 30m minimum drop.  The list is co-authored by Myrddyn Phillips and Aled Williams, with the introduction to the Mapping Mountains publication of the list appearing on the 30th January 2017.

The hill is adjoined to the Beacon Hill range of hills, which are situated in the north-eastern part of Mid and West Wales (Region B, Sub-Region B1), and is positioned between the B4355 road to the north-east and the A488 road to the south-east, and has the small town of Tref-y-clawdd (Knighton) to the east.

Bwlch Bank (SO 242 720)

The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website under the name of Bailey Hill.  Hill list authors are prone to list a hill by the name that appears nearest to its summit on contemporary Ordnance Survey maps, without much consideration for its local or historical confirmation, or whether map placement is appropriate, and in the case of this hill it was examination of Ordnance Survey historical maps and local enquiry that confirmed the name of the hill and the land area that constitutes that of Bailey Hill respectively.

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 historical 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 Interactive Coverage Map hosted on the Geograph website.  Two of the historical maps now available are the Ordnance Survey Draft Surveyors map which formed the basis for the Ordnance Survey One-Inch ‘Old Series’ map, and it was the former of these maps that name the hill as Bwlch Bank.

Extract from the Ordnance Survey Draft Surveyors map

The Draft Surveyors maps consist of the preliminary drawings made by the Ordnance Survey’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.

The placement of names on maps from one scale to another and from one edition to another are prone to be moved over time, however study has shown that one of the best publicly available Ordnance Survey maps for name placement is the 1:25,000 historical map and this map also shows the name of Bwlch Bank adjoined to this hill.

Extract from the Ordnance Survey 1:25,000 historical map

When visiting this hill place-name enquiries were made with a number of local farmers and Bailey Hill was confirmed to take in a large area associated with a number of individual hills and is not applicable just to this hill, this is in evidence on the Ordnance Survey Draft Surveyors Map as well as the historical 1:25,000 map, both of which use the name of Bailey Hill as an elongated ridge name, whereas the contemporary 1:25,000 Explorer map dispenses with the use of an elongated ridge name giving the impression that this name is applicable just to one hill and not a large area of land taking in more than just this one hill.

Therefore, the name this hill is now listed by in the Y Pedwarau is Bwlch Bank, and this was derived from the Ordnance Survey Draft Surveyors map and substantiated by the Ordnance Survey historical 1:25,000 map, with the land area taking in Bailey Hill confirmed by local enquiry.

Fountain Head Well Field (SO 231 722) - 30th significant name change

Survey post for Fountain Head Well Field


There has been a Significant Name Change to a hill that was surveyed for inclusion in the listing of the Y Pedwarau, with the summit height, drop and status of the hill confirmed by a survey with the Trimble GeoXH 6000 which took place on the 19th April 2018.

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

Y Pedwarau – Welsh hills at and above 400m and below 500m in height that have 30m minimum drop.  Accompanying the main list of the Y Pedwarau are five categories of sub hills, with this hill being surveyed for inclusion in the 400m Sub-Pedwarau.  The criteria for 400m Sub-Pedwar status are all Welsh hills at and above 400m and below 500m in height that have 20m and more and below 30m of drop.
The list is co-authored by Myrddyn Phillips and Aled Williams, with the introduction to the Mapping Mountains publication of the list appearing on the 30th January 2017.

The hill is adjoined to the Beacon Hill range of hills, which are situated in the north-eastern part of Mid and West Wales (Region B, Sub-Region B1), and it is positioned between the B4356 road to the south-west and the B4355 road to the north-east, and has the small town of Tref-y-clawdd (Knighton) to the east.

Prior to the survey with the Trimble GeoXH 6000 for this hill’s potential inclusion as a 400m Sub-Pedwar it was not classified having not appeared in any known listing of hills.  Therefore, although there is no change in this hill’s listed name it is worth categorising under the heading of Significant Name Changes as the name of the field where the summit of this hill is situated has come from local enquiry. 

When visiting this hill and surveying its summit and bwlch I met David Williams who farms from White Anthony (SO 258 731), with his family’s farm being Fountain Head (SO 228 727), David told me that the hill I had just visited was a part of Fountain Head’s land and although the hill itself did not have a name, the field where the summit is situated is known as Fountain Head Well Field as there is a well at the top, this is a small covered reservoir that is housed in an old fenced compound.

Therefore, the name this hill is now listed by is Fountain Head Well Field, and this was derived from local enquiry.

There has been a Significant Name Change to a hill that is listed in the Y Pedwarau, with the summit height, drop and status of the hill derived from LIDAR analysis conducted by Aled Williams and subsequently confirmed by a survey with the Trimble GeoXH 6000 which took place on the 19th April 2018.

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

Y Pedwarau – Welsh hills at and above 400m and below 500m in height that have 30m minimum drop.  The list is co-authored by Myrddyn Phillips and Aled Williams, with the introduction to the Mapping Mountains publication of the list appearing on the 30th January 2017.

The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website under the partly invented name of Downes’s Dingle Hill, with an accompanying note stating; Name from dingle to the South. 



Downes's Dingle Hill  406m  SO250726  137/148201  Name from dingle to the South.



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 PenBryn or Moel in front of them or as in this instance, use the name of a dingle and add the word Hill.  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.

Extract from the Ordnance Survey 1:25,000 Explorer map


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 historical 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 Interactive Coverage Map hosted on the Geograph website.  Two of the historical maps now available are the Ordnance Survey Draft Surveyors map which formed the basis for the Ordnance Survey One-Inch ‘Old Series’ map, and it was the former of these maps that name the hill as Waun Sidan.

Graig Wen (SH 694 068) - 28th significant name change

Survey post for Graig Wen


There has been a Significant Name Change to a hill that is listed in the Y Pedwarau, with the summit height and drop of the hill being confirmed by a survey with the Trimble GeoXH 6000 which was conducted on the 1st April 2018.

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

Y Pedwarau – These are the Welsh hills at and above 400m and below 500m in height that have 30m minimum drop.  The list is co-authored by Myrddyn Phillips and Aled Williams, with the introduction to the Mapping Mountains publication of the list appearing on the 30th January 2017.

The hill is adjoined to the Tarennydd range of hills, which are situated in the south-western part of North Wales (Region A, Sub-Region A3), and it is positioned above the B 4405 road and the small community of Abergynolwyn which are to its west.

Graig Wen (SH 694 068)


The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website under the name of Foel Pandy, and this is also the name that the hill was listed by in the Y Pedwarau (Europeaklist, May 2013). 




Foel Pandy    454m    SH694068    12423



Hill list authors are prone to list a hill by the name that appears nearest to its summit on contemporary Ordnance Survey maps, without much consideration for its local or historical confirmation, or whether map placement is appropriate, and in the case of this hill there are two names that are consistently applied on different scaled Ordnance Survey maps to land near this hill’s summit, these names are Graig Wen and Foel Pandy.



Extract from the Ordnance Survey 1:25,000 Explorer map

Since this hill was first listed there is a greater understanding amongst some hill list authors relating to the cynefin naming system:

Many Welsh hills comprise bounded land that is separated either by a fence or wall; these boundaries indicate land that is adjoined to different owners or tenants.  These land boundaries have usually been in place for centuries and in the uplands of Wales they are referred to as the cynefin, or sheep-walk in English.

The sheep-walk is an English term given to enclosed land that is apportioned to a specific farm.  The Welsh term for this land is cynefin, which can be literally translated as habitat, as in that for the sheep.  The cynefin usually takes in land that is known as the mountain land of the specific farm, therefore the name given to this enclosed land is usually that of the name of the farm prefixed with the word mynydd (mountain), this land is usually given over for sheep grazing, hence the term sheep-walk.  When Ordnance Survey maps are examined one can find many examples where this form of cynefin naming system exists, with farms situated in valley’s having their name given to high mountain land and prefixed with the word mynydd.

The bounded land given over to specific farms also takes in middle ground between the higher mountain land and the lower pasture land of the valley, this is known in Welsh as the ffridd and can take in a variety of habitats including heath, moor, grassland, woodland and high pasture.  Again, when Ordnance Survey maps are examined one can find many examples of names prefixed with the word Ffridd, and its apportionment to a specific hill is dependent upon where the bounded land is situated and referring to the Tithe maps for confirmation is then advised.

It is the cynefin naming system that usually results in a hill being known by different names in opposing valleys, as in many instances the upper bounded land meet at the watershed on top of the summit ridge and therefore the same hill would be known by two different names, each name a part of a different farm’s cynefin.  

Although it is usual for the mountain land of a farm to be prefixed by the word mynydd and followed by that of the farm name, on occasion this does not happen, and this is such a case as the name Foel Pandy is considered a cynefin name, with the farm of Maes-y-pandy situated between Abergynolwyn and Tal-y-llyn.  Contemporary Ordnance Survey maps also name the wood below the bounded land of Foel Pandy as Foel Pandy Wood, in affect this bounded land is adjoined to this farm.

Therefore, as a name for a hill is prioritised over that of a cynefin name for listing purposes, this hill is now listed in the Y Pedwarau as Graig Wen.

There has been a Significant Name Change to a hill that is listed in the Y Pedwarau, with the summit height and its position being confirmed by a survey with the Trimble GeoXH 6000 which was conducted on the 15th February 2018.

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

Y Pedwarau – These are the Welsh hills at and above 400m and below 500m in height that have 30m minimum drop.  The list is co-authored by Myrddyn Phillips and Aled Williams, with the introduction to the Mapping Mountains publication of the list appearing on the 30th January 2017.

The hill is a part of the Maelienydd range, this group of hills is situated in the eastern part of Mid and West Wales and are also known as the Beacon Hill range, with the hill being encircled by a number of minor roads with the B 4365 to its west and has the small town of Trefyclo (Knighton) towards the north.

Farrington Bank (SO 305 699)

The hill appeared in the 400m P30 list on Geoff Crwder’s v-g.me website under the name of Llan-wen Hill North-East Top, with the name of Llan-wen Hill appearing adjacent to a track 1km to the south-west of the listed summit on Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps of the day.

During my early hill listing I paid little regard to name placement on a 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 inappropriate, and supplanting the name Llan-wen Hill and adding a directional element to it, is such an example, as this name has been consistently applied on Ordnance Survey maps to a 404m map heighted hill positioned at SO 296 694 to the south-west of, and separate from, the hill this article relates to. 

Extract from the Ordnance Survey 1:25,000 Explorer map

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 historical 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 enlarged map hosted on the Geograph website.  Two of the historical maps now available are the Ordnance Survey Draft Surveyors map which formed the basis for the Ordnance Survey One-Inch ‘Old Series’ map, and it was the former of these maps that name the hill as Farrington Bank.

Extract from the Ordnance Survey Draft Surveyors map

The Draft Surveyors maps consist of the preliminary drawings made by the Ordnance Survey’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 for 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.

Therefore, the name this hill is now listed by in the Y Pedwarau is Farrington Bank and this was derived from the Ordnance Survey Draft Surveyors map.

Banc y Cwm (SN 968 470) - 26th significant name change

Survey post for Banc y Cwm


There has been a Significant Name Change to a hill that is listed in the Y Pedwarau, with the summit height, drop and status of the hill confirmed by a Trimble GeoXH 6000 survey conducted by Myrddyn Phillips which took place on the 28th December 2017.

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

Y Pedwarau – Welsh hills at and above 400m and below 500m in height that have 30m minimum drop.

The list is co-authored by Myrddyn Phillips and Aled Williams, with the 1st edition of the list having been published by Europeaklist in May 2013 and by Haroldstreet in January 2014, and the Introduction to the Mapping Mountains publication of this list appearing on the 30th January 2017.

The hill is adjoined to the Mynydd Epynt range of hills which are situated in the south-easterly part of Mid and West Wales (Region B, Sub-Region B2), and it is positioned above the B 4519 road which is to its south-west and has the small community of Llangamarch (Llangammarch Wells) to its east, Garth to its north north-west and Cilmeri (Cilmery) towards its north-east.

Banc y Cwm (SN 968 470)

The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website in the Hills to be surveyed sub list under the name of The Warren.  Hill list authors are prone to list a hill by the name that appears nearest to its summit on contemporary Ordnance Survey maps, without much consideration for its local or historical confirmation, or whether map placement is appropriate, and in the case of this hill there are two names that are consistently applied on different scaled Ordnance Survey maps to land near this hill’s summit, these names are Banc y Cwm and The Warren.


The Warren      467m      SN968470      147188


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 historical such as the Draft Surveyors map and the One-Inch ‘Old Series’ map, whilst others are current and digitally updated such as the Interactive Coverage Map hosted on the Geograph website.  One of the historical maps now available is the series of Ordnance Survey Six-Inch maps, these formed the base map for many years until they were replaced by the 1:10,000 series, and study has shown that these maps along with the Historical 1:25,000 map are some of the best produced by Ordnance Survey for name placement.

Extract from the Ordnance Survey 1:50,000 Landranger map

Extract from the series of Ordnance Survey Six-Inch maps

In this case it was research via the series of historical Ordnance Survey maps available online coupled with local enquiries that confirmed that the name of Banc y Cwm would be appropriate to use for this hill. 

Therefore, the name this hill is now listed by in the Y Pedwarau is Banc y Cwm and this was derived from historical and contemporary Ordnance Survey maps and local enquiry.

Carneddau (SO 066 540) - 25th significant name change

Survey post for Carneddau


There has been a Significant Name Change to a hill that is listed in the Y Pedwarau, with the summit height and drop of the hill analysed via LIDAR data by Aled Williams and subsequently confirmed by a Trimble GeoXH 6000 survey which took place on the 6th October 2017.

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

Y Pedwarau – Welsh hills at and above 400m and below 500m in height that have 30m minimum drop.  The list is co-authored by Myrddyn Phillips and Aled Williams, with the Introduction to the Mapping Mountains publication of this list appearing on the 30th January 2017.

The hill is adjoined to the Fforest Glud range of hills which are situated in the eastern part of Mid and West Wales (Region B, Sub-Region B1), and it is positioned between the town of Llanfair-ym-Muallt (Builth Wells) to the south-west and the small community of Hundred House to the east.

Carneddau (SO 066 540)

The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website under the directional name of Carneddau South Top, with an accompanying note stating Name from hill to the North.  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 PenBryn or Moel in front of them.  On occasion I also used a directional name based on supplanting the name of a higher hill and adding a directional component to the name.  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 in the case of this hill it was four local farmers who told me that the land where this hill is situated is a part of the Carneddau, and this is substantiated by historical and contemporary Ordnance Survey maps.  Therefore, as a directional name only adds an invented component to the name of the hill, this is dispensed with in favour of the name that is in use locally.


Carneddau South Top432mSO067541147200Name from hill to the North


The first local farmer I asked about this hill and its name was Sandy Price who farms from Upper Pentre which is below the hill to its south-east, Sandy told me that this hill is a part of the Carneddau (pronouncing it as the Car-neth-ee) hill and that he had never heard separate names for any of the hills that I was describing.  This is where the mind of a hill bagger is distinctly different to that of a farmer / grazer, as Sandy thought of all this land as one hill, whist a hill bagger would distinguish the land taking in the Carneddau hill as four separate P30s.  Sandy then suggested I visit Colin Wheel who farms from Ddole.  I then visited Rhiwlas; the farm above Upper Pentre, Sandy’s neighbour was out early in the morning and smiled as I huffed and puffed up the steep lane, he also confirmed that the hill is a part of the Carneddau hill.  Later in the day after I’d visited the various P30s taking in the Carneddau hill I visited Colin Wheel and his brother Jim.  Colin is aged 71 and Jim 85 and both were doing work on their farm, Colin on a quad bike and Jim tending to a tractor.  They have farmed this area all of their lives and were a delight to speak with, with smiles and hospitality, they also gave me the same information as I was given earlier in the day, the hill is known as the Carneddau and this takes in much of the land that today is designated open access land and some of the enclosed land on its eastern side, and that there are no separate names for any of the P30s, as in a farmers / grazers mind they are a part of the same hill, which is known as the Carneddau.

This information is substantiated by a number of historical maps, some of which are presented below.

Survey post for Cefn Digoll


There has been a Significant Name Change to a hill that is listed in the Y Pedwarau and Y Trechol - The Dominant Hills of Waleswith the height, drop and dominance of the hill being confirmed by a Trimble GeoXH 6000 survey which took place on the 24th and 28th March 2017, with the bwlch of the hill also analysed via LIDAR data by Aled Williams.

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

Y Pedwarau These are the Welsh hills at and above 400m and below 500m in height that have 30m minimum drop.  The list is co-authored by Myrddyn Phillips and Aled Williams, with the introduction to the Mapping Mountains publication of this list appearing on the 30th January 2017.

Y Trechol - The Dominant Hills of Wales - These are the Welsh P30 hills whose prominence equal or exceed half that of their absolute height.  The list is authored by Myrddyn Phillips.

The hill is a part of the Cefn Digoll range, this group of hills is situated in the north-eastern part of Mid and West Wales (Region B, Sub-Region B1), and is positioned above the A 483 road and the village of Trewern to its north and the town of Y Trallwng (Welshpool) to its west north-west.  

The summit of Cefn Digoll

The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website under the name Beacon Ring, this is the English name given to the summit area of the hill, with its Welsh counterpart being Caer Digoll.  During my early hill listing I did not lay emphasis on prioritising a name for a hill over that for its summit, and therefore on occasion I used a summit name in preference to that of the hill name, and the use of Beacon Ring is such an example as the hill is known in English as the Long Mountain.  This practice can be appropriate if the summit name is prioritised locally, otherwise for listing purposes it is customary to prioritise the hill name in preference to that of its summit.
  

Beacon Ring  408m  SJ265058  126216  Marilyn. Clem/Yeaman. Trig pillar marked on map.


Also during my early hill listing I thought it sufficient to use English or anglicised names for hills even if a Welsh name existed, this in the main is not a practice that I now advocate, especially if the Welsh name has historical evidence of use, and as the English names for this hill and its summit have Welsh counterparts, these being Cefn Digoll and Caer Digoll respectively, the hill name of Cefn Digoll is being used. 

Therefore, the name this hill is now listed by in the Y Pedwarau and Y Trechol – The Dominant Hills of Wales is Cefn Digoll, as this is the Welsh name for the hill.

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

Y Pellennig –The Remotest Hills of Wales comprise all Welsh hills whose summit is 2.5km or more from the nearest paved public road and which have a minimum 15m of drop.  The list is co-authored by Myrddyn Phillips and Aled Williams.

Y Pedwarau These are the Welsh hills at and above 400m and below 500m in height that have 30m minimum drop.  The list is co-authored by Myrddyn Phillips and Aled Williams, with the introduction to the Mapping Mountains publication of this list appearing on the 30th January 2017.

Esgair Cerrig (SN 952 432)

The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website under the name Twyn Rhyd-car North Top, with an accompanying note stating Name from hill to the south.  Hill list authors are prone to list a hill by the name that appears nearest to its summit on Ordnance Survey maps, without much consideration for its local or historical confirmation, or whether map placement is appropriate, and when the hill is unnamed on Ordnance Survey maps list authors are prone to either invent a name for the hill, supplant a name from a near feature that can result in an inappropriate name or they can use a directional name from a near named hill, and in the case of this hill it was the latter that I opted for, using the name of Twyn Rhyd Car and adding the directional element of North Top.

The hill is a part of the Mynydd Epynt range, which is a group of hills situated in the south-eastern part of Mid and West Wales (Region B, Sub-Region B-2), and it is positioned above the small town of Llanwrtyd (Llanwrtyd Wells) to its north-west and Llangamarch (Llangammarch Wells) to its north. 

Esgair Fawr (SN 927 433)

The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website under the name Ffynnon Bevan, with an accompanying note stating that this is a trig point name.

Hill list authors are prone to list a hill by the name that appears nearest to its summit on Ordnance Survey maps, without much consideration for its local or historical confirmation, or whether map placement is appropriate, and in the case of Ffynnon Bevan this name is presented on Ordnance Survey maps south-westward of this hill’s summit as Fynnon Dafydd Bevan and is applicable to a spring beside an old farm house.  Although the Ordnance Survey have been responsible for the documenting of many thousands of Welsh upland place-names, and in the process of doing so they have also saved an unprecedented number of these names from being lost, they are also responsible for using names that are not the most appropriate, although in their defence of this name, all they have done is name a trig pillar and not necessarily the hill.  However, this is an example where the supplanting of a name can easily lead an ill-informed hill list author down a route that lists a hill by an inappropriate name.   

With time and inclination place-name data can be improved by asking local people and examining historical documents, and in the case of this hill it was a local farmer who gave the name Esgair Fawr for land taking in the summit of this hill.

Therefore, the name this hill is now listed by in the Y Pedwarau is Esgair Fawr and this was derived from local enquiry.

There has been a Significant Name Change to a hill that is listed in the Y Pedwarau and Y Trechol - The Dominant Hills of Waleswith the summit height and dominance of the hill being confirmed by a survey with the Trimble GeoXH 6000 which was conducted on the 28th December 2016, with the hill previously analysed via LIDAR data by Aled Williams.

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

Y Pedwarau These are the Welsh hills at and above 400m and below 500m in height that have 30m minimum drop.  The list is co-authored by Myrddyn Phillips and Aled Williams, with the introduction to the Mapping Mountains publication of this list appearing on the 30th January 2017.

Y Trechol - The Dominant Hills of Wales - These are the Welsh P30 hills whose prominence equal or exceed half that of their absolute height.  With the criteria for Lesser Dominant status being those addition Welsh P30 hills whose prominence is 33% or more and below 50% of their absolute height.  The list is authored by Myrddyn Phillips.

The hill is a part of the Mynydd Epynt range, this group of hills is situated in the south-eastern part of Mid and West Wales (Region B, Sub-Region B-2), and is positioned above the B 4519 road and between the small communities of Garth to its north and Upper Chapel to its south-east.

The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website under the name Mynydd Eppynt, which is the composition of the name that appeared relatively close to the summit of the hill on Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps of the day.

Hill list authors are prone to list a hill by the name that appears nearest to its summit on Ordnance Survey maps, without much consideration for its local or historical confirmation, or whether map placement is appropriate, and in the case of Mynydd Eppynt (the name is now presented on Ordnance Survey maps with a single ‘p’ as Mynydd Epynt) the name is more appropriately associated with the hill range rather than an individual hill.  However, place-name data can be improved by asking local people and examining historical documents, and in the case of this hill it was a local farmer who gave the name Clepyn Melyn for land near to the summit of the hill, which to the authors knowledge is the main named feature of this hill and therefore appropriate to use for listing purposes.

Therefore, the name this hill is listed by in Y Pedwarau and Y Trechol - The Dominant Hills of Wales is Clepyn Melyn and this was derived from local enquiry.


The full details for the hill are:

Weston Bank (SO 199 702) - 19th significant name change

Survey post for Weston Bank


There has been a Significant Name Change to a hill that is listed in the Y Pedwarauwith the height and drop of the hill being confirmed by a survey with the Trimble GeoXH 6000 which was conducted on the 8th April 2016.

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

Y Pedwarau These are the Welsh hills at and above 400m and below 500m in height that have 30m minimum drop.  The list is co-authored by Myrddyn Phillips and Aled Williams, with the introduction to the Mapping Mountains publication of this list appearing on the 30th January 2017.

The hill is a part of the Fforest Glud range, this group of hills is situated in the eastern part of Mid and West Wales and are known as the Radnor Forest in English, and the hill is positioned between the small communities of Llangunllo to the north-east and Bleddfa to the south south-east.

The Trimble GeoXH 6000 gathering data at the summit of Weston Bank

The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website under the name of Pen-y-clawdd Hill, which is a name that appeared close to the summit of the hill on Ordnance Survey 1:25,000 Explorer maps of the day.

    136/148
  200/214
  

During my early hill listing I paid little regard to name placement on a 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 inappropriate, and Pen-y-clawdd Hill is such an example as this name has been consistently applied on Ordnance Survey maps that endeavour to use appropriate name placement to a c 401m high hill that stretches from SO 193 705 to land taking in a c 400m rise at SO 190 702.  The land of Pen-y-clawdd Hill is considered separate from that of the land associated with the hill that this blog post relates to.

Appropriate name placement for Pen-y-clawdd Hill on the Ordnance Survey 1:25,000 historical map

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 historical 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 enlarged map hosted on the Geograph website.  Two of the historical maps now available are the Ordnance Survey Draft Surveyors map which formed the basis for the Ordnance Survey One-Inch ‘Old Series’ map, and it was the former of these maps that name the hill as Weston Bank.

Extract from the Ordnance Surveys Draft Surveyors map

The Draft Surveyors maps consist of the preliminary drawings made by the Ordnance Survey’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. 

Therefore, the name this hill is now listed by in Y Pedwarau is Weston Bank and this was derived from the Ordnance Survey Draft Surveyors map.

There has been a Significant Name Change to a hill that is listed in the Y Pedwarau, and the following details are in respect of a hill that was surveyed with the Trimble GeoXH 6000 on the 25th September 2015.

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

The hill is a part of the Elenydd range, which forms one of the largest hill groups in the country and is situated in the central part of mid and west Wales.  The hill is on the south-eastern periphery of this hill range and is positioned above the small town of Llanwrtyd (Llanwrtyd Wells) to its east.

Extract from the Ordnance Survey One-Inch 'Old Series' map


Extract from the series of Ordnance Survey Six-Inch maps

The One-Inch ‘Old Series’ was the first map that Ordnance Survey published, and these maps were based on the preceding 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.

Therefore the name this hill is now listed by in Y Pedwarau is Pen Twyn and this was derived from the Ordnance Survey One-Inch ‘Old Series’ map and later confirmed by the series of Ordnance Survey Six-Inch maps.

Mynydd Tŷ Cerrig (SJ 147 405)

The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website under the invented name of Pen Ty’n-y-graig, with an accompanying note stating; Name from wood to the North-East, with Ty’n-y-graig  being the name of a farm and its adjacent wood; Coed Ty’n-y-graig.

During my early hill listing I thought it appropriate to invent a name for a hill if no name seemed to appear for it on Ordnance Survey maps of the day.  My preference was to use farm names and put PenBryn or Moel in front of them.  This is not a practice that I now advocate as with research either conducted locally or historically an appropriate name for the hill can usually be found and it was local enquiry that gave the name of Mynydd Tŷ Cerrig for this hill.

Therefore, the name this hill is now listed by in the Y Pedwarau is Mynydd Tŷ Cerrig (conforming to standard modern Welsh), and this was derived from local enquiry.

Mapping Mountains - Significant Name Changes - Y Pedwarau

Gaer Fach (SO 009 366) - 11th significant name change

Survey post for Gaer Fach


There has been a Significant Name Change to a hill that is listed in the Y Pedwarau, and the following details are in respect of a hill that was surveyed with the Trimble GeoXH 6000 on the 18th August 2015.

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

Y Pedwarau These are the Welsh hills at and above 400m and below 500m in height that have 30m minimum drop.  The list is co-authored by Myrddyn Phillips and Aled Williams, and the introduction to the Mapping Mountains publication of this list appeared on the 30th January 2017.

The hill is a part of the Mynydd Epynt range, which is a group of hills situated in the south-eastern part of mid and west Wales.  The hill is positioned between the small communities of Merthyr Cynog to the west north-west and Lower Chapel to the east south-east.

Gaer Fach (SO 009 366)

The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website under the partly invented name Pen Gaer Fach, with an accompanying note stating; Name from summit hillfort.  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 PenBryn or Moel in front of them or as in this instance, use the name of the summit hillfort and add the word Pen.  This is not a practice that I now advocate as with research either conducted locally or historically an appropriate name for the hill can usually be found.

    Name from summit hillfort
  

As an appropriate name for this hill already exists on contemporary Ordnance Survey maps; Gaer Fach, the invented and prefixed word of Pen is wholly unnecessary and therefore the name this hill is now listed by in Y Pedwarau is Gaer Fach.  

Extract from the current Ordnance Survey 1:25,000 Explorer map

Please note, the current Ordnance Survey enlarged map hosted on the Geograph website gives the composition of this name as Caer fach, in this instance it is appropriate to use Gaer with a ‘G’ and Fach with a capital ‘F’.

Y Graig Wen (SJ 240 371) - 10th significant name change

Survey post for Y Graig Wen


There has been a Significant Name Change to a hill that is listed in the Y Pedwarau, and the following details are in respect of a hill that was surveyed with the Trimble GeoXH 6000 on the 17th July 2015.

The criteria for the list that this name change affects are:

The hill is a part of the Y Berwyn range, which is an extensive group of hills situated in the south-eastern part of north Wales.  The hill is positioned between the small communities of Llwynmawr to the west, Craignant and Selattyn to the south-east and Bronygarth to the east.

The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website under the invented name Pen Llwynmawr, with an accompanying note stating; Name from village to the 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 PenBryn or Moel in front of them, or as in this instance, use the name of a near village.  This is not a practice that I now advocate as with research either conducted locally or historically an appropriate name for the hill can usually be found.

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 historical 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 enlarged map on the Geograph website.  One of the historical 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. 


Extract from the Ordnance Survey Draft Surveyors map naming the hill as Y Graig Wen

The Draft Surveyors maps consist of the preliminary drawings made by the Ordnance Survey’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. 

Therefore, the name this hill is now listed by in the Y Pedwarau is Y Graig Wen, and this was derived from the Ordnance Survey Draft Surveyors map.

There has been a Significant Name Change to a hill that is listed in the Y Pedwarau, with positions for the summit and bwlch being surveyed with the Trimble GeoXH 6000 on the 17th July 2015, and LIDAR subsequently prioritised for both.

There has been a Significant Name Change to a hill that appears in the Y Pedwarau, and the following details are in respect of a hill that was surveyed with the Trimble GeoXH 6000 on the 13th May 2015.

The criteria for the list that this name change affects are:

Y Pedwarau These are the Welsh hills at and above 400m and below 500m in height that have 30m minimum drop.  The list is co-authored by Myrddyn Phillips and Aled Williams, and the introduction to the Mapping Mountains publication of this list appeared on the 30th January 2017.

The hill is adjoined to the Aran group of hills which is situated in the south-western part of north Wales.  The hill is positioned between the small communities of Aberllefenni to its west and Aberangell to its east and is enclosed by the Dyfi Forest to its north, south and east.

Mynydd Coch (SH 804 099)

The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website under the name Mynydd Cwmcelli.  The name of Mynydd Cwmcelli appears on the Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map approximately 1 km west north-westward from this hill’s summit and is consistently placed on Ordnance Survey maps applicable to a 408m map heighted hill whose summit is positioned at SH 795 101.

During my early hill listing I used the map name that appeared closest to the summit of the listed hill or which seemed most appropriate for the hill, without due consideration for its positional value, doing so can perpetuate the use of inappropriate names.  As the 408m map heighted hill seemed of little consequence and was not then listed the use of its name for another hill did not seem inappropriate.  This is not a practice that I now advocate as with research either conducted locally or historically a more appropriate name for the hill can usually be found.

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 historical 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 enlarged map on the Geograph website.  One of the historical 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.  In the case of this hill it was Aled Williams who conducted extensive research and studied the Draft Surveyors map in conjunction with other maps relating to land boundaries that necessitated the change in this hill’s listed name.

The One-Inch ‘Old Series’ was the first map that Ordnance Survey published, and  they were based on the preceding 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.

Survey post for Cerrig Coegion


There has been a Significant Name Change to a hill that appears in the following lists; Y Pellennig - The Remotest Hills of Wales and Y Pedwarauwith the following details relating to a hill that was surveyed with the Trimble GeoXH 6000 on the 10th July 2014.

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

Y Pellennig –The Remotest Hills of Wales comprise all Welsh hills whose summit is 2.5km or more from the nearest paved public road and which have a minimum 15m of drop.  The list is co-authored by Myrddyn Phillips and Aled Williams.

Y Pedwarau These are the Welsh hills at and above 400m and below 500m in height that have 30m minimum drop,  with the introduction to the publication of this list on Mapping Mountains appearing on the 30th January 2017.  The list is co-authored by Myrddyn Phillips and Aled Williams.

The hill is situated in the Y Mynydd Du, this range of hills forms the western part of the Brecon Beacons National Park (Parc Cenedlaethol Bannau Brycheiniog), and takes in the remotest land in mainland Wales with the hill listed as the third remotest in distance from its summit to the nearest paved public road in the whole of mainland Wales.  The nearest towns to the hill are Ystradgynlais to the south and the small community of Glyntawe to the east.

The hill first made an appearance in a hill list as Pen Bwlch y Ddeuwynt in the The Welsh 400m Peaks which was compiled by Myrddyn Phillips and made available to the rhb Yahoo Group file database by Rob Woodall in 2002.  This listing was subsequently published on Geoff Crowder’s v-g.me website in 2004 and was the originator for the list named Y Pedwarau and which is now co-authored with Aled Williams.

The hill originally appeared in the rhb Yahoo Group file database and the v-g.me website under an invented name; Pen Bwlch y Ddeuwynt, with an accompanying note on the v-g.me website stating; Name from bwlch to the North-West.  As was my liking during my early hill listing I thought it appropriate to invent a name for a hill if no name seemed to appear for it on Ordnance Survey maps of the day.  My preference was to use the nearest name to the summit that appeared on the map and prefix it with the word Pen, Bryn or Moel.  This is not a practice that I now advocate as with research either conducted locally or historically an appropriate name for the hill can usually be found.  Extensive place-name research has subsequently taken place for the hill range of Y Mynydd Du and these details are included in Y Pedwarau and Y Pellennig – The Remotest Hills of Wales.

The name this hill is now listed by in the Y Pedwarau and Y Pellennig – The Remotest Hills of Wales is Cerrig Coegion.  This name was derived from local enquiry as well as historical documentation with the following brief explanation appearing in the booklet version of Y Pellennig – The Remotest Hills of Wales:

The name is also recorded in ‘Bugail y Mynydd Du’ by Rhys Davies.

Mapping Mountains - Significant Name Changes - Y Pedwarau

Foel Fawr (SN 900 904) - 1st significant name change

Survey post for Foel Fawr


There has been a Significant Name Change to a hill that is listed in the Y Pedwarauwith the following details relating to a hill that was surveyed with the Trimble GeoXH 6000 on the 18th April 2014.

The criteria for the list that this name change affects are:

Y Pedwarau These are the Welsh hills at and above 400m and below 500m in height that have 30m minimum drop,  with the introduction to the publication of this list on Mapping Mountains appearing on the 30th January 2017.  The list is co-authored by Myrddyn Phillips and Aled Williams.

The hill is part of the Pumlumon range, which is an extensive group of hills situated in the north-western part of mid and west Wales, and is positioned between the small communities of Penffordd-las (Staylittle) to the north-west and Llawr-y-glyn to the east north-east, with the reservoir of Llyn Clywedog to the hill’s south.

The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website under the name Bryn yr Hwrdd, this name appears on the Ordnance Survey 1:25,000 Explorer map over 1 km north-westward from this hill’s summit and is consistently placed on Ordnance Survey maps applicable to land centred at SN 899 911.    

During my early hill listing I used the map name that appeared closest to the summit of the listed hill or which seemed most appropriate for the hill, without due consideration for its positional value, doing so can perpetuate the use of inappropriate names.  This is not a practice that I now advocate as with research either conducted locally or historically a more appropriate name for the hill can usually be found.

The name this hill is now listed by in the Y Pedwarau is Foel Fawr, and this was derived from the Ordnance Survey enlarged mapping that is hosted on the Geograph website.  This mapping became publicly available after the original P30 lists were published on Geoff Crowder's v-g.me website.

Since the publication of these P30 lists there have been a number of historical Ordnance Survey maps made available online, including the series of Six-Inch maps on the National Library of Scotland website, much of the place-name information on these maps were the source for what now appears on the Ordnance Survey enlarged mapping hosted on the Geograph website.
