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.

The hill appeared in the original Welsh 300m P30 list on Geoff Crowder’s v-g.me website, under the invented and transposed name of Pen y Clogau, with an accompanying note stating; Name from mine to the West.
Pen y Clogau | 310m | SH678201 | 124 | 18 | Name from mine 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 Pen, Bryn or Moel in front of them or as in this instance transpose the name of a mine and prefix it with the words Pen y. 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.

Therefore, the name this hill is now listed by in the Y Trichant – The 300m Hills of Wales is Pt. 310.4m, and this is being used as the author has not found an appropriate name for the hill either through historic research and / or local enquiry.

Pt. 385m (SH 627 326) - 139th Significant Name Change
Hill Reclassifications post for Pt. 385m
There has been a Significant Name Change to a hill that is listed in the Y Trichant – The 300m Hills of Wales, with the summit height, bwlch height and their locations, the drop and status of the hill derived from detail on contemporary maps produced from Ordnance Survey data.
The criteria for the list 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 hill appeared in the original Welsh 300m P30 list on Geoff Crowder’s v-g.me website, under the invented and transposed name of Pen y Fedw, with an accompanying note stating; Name from lake to the North-West.
Pen y Fedw | 380c | SH628326 | 124 | 18 | Name from lake to the North-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 or as in this instance transpose the name of a lake and prefix it with the word Pen.

However, occasionally even when research is conducted an appropriate name for the hill may not be found, and on such occasions the listing protocol is to use the point (Pt. 385m) notation, and for this hill this is such an example.
Therefore, the name this hill is now listed by in the Y Trichant – The 300m Hills of Wales is Pt. 385m, and this is being used as the author has not found an appropriate name for the hill either through historic research and / or local enquiry.

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 that was hosted on the Geograph website and which was entitled the Interactive Coverage Map and the interactive mapping on the Magic Maps and WalkLakes websites. Two of the historic maps now available are 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 these maps that form the basis for the change in the listed name of this hill.
The Draft Surveyors maps consist of the preliminary drawings made by Ordnance Survey 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, it is this map that gives the originating Welsh name for this hill.

Therefore, the name this hill is now listed by in the Y Trichant – The 300m Hills of Wales is Garth, and this was derived from the Ordnance Survey Draft Surveyors map and the One-Inch ‘Old Series’ map, with the Welsh name for this hill prioritised over its part English counterpart, which for listing purposes is standard practice.

The hill appeared in the original Welsh 300m P30 list on Geoff Crowder’s v-g.me website, under the invented and transposed name of Pen-y-Branas, with an accompanying note stating; Name from lodge to the South.
Pen-y-Branas | 380m | SJ016387 | 125 | 255 | Name from lodge 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 Pen, Bryn or Moel in front of them or as in this instance transpose the name of a lodge and prefix it with the words Pen-y-. 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.

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 transpose the name of a lake and prefix it with the word Pen.

However, occasionally even when research is conducted an appropriate name for the hill may not be found, and on such occasions the listing protocol is to use the point (Pt. 395.9m) notation, and for this hill this is such an example.
Therefore, the name this hill is now listed by in the Y Trichant – The 300m Hills of Wales is Pt. 395.9m, and this is being used as the author has not found an appropriate name for the hill either through historic research and / or local enquiry.

The hill appeared in the original Welsh 400m P30 list published on Geoff Crowder’s v-g.me website under the name of Cefn Branddu, which is a prominent name that appears to the north-east of this hill’s summit on the contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map. This is also the name the hill was listed by in the 1st edition of the Y Pedwarau published by Europeaklist in May 2013.

After visiting this hill we descended to Aber Branddu and met Irwel and his father; Eirwyn. With the Ordnance Survey 1:25,000 Explorer map opened on the roof of my car and the hill directly above us, Aled proceeded to ask questions about this hill and others where Irwel grazes sheep on. Many upland place-names proceeded to be given, including that of Cnepyn Cerrig for this hill.

When the original 300m height band of Welsh P30 hills were published on Geoff Crowder’s v-g.me website, this hill was listed under the transposed name of Pen-y-bryn, which is a prominent name adjoined to a farm that appears near the summit of this hill on contemporary Ordnance Survey maps.

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.

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.

The hill appeared in the original 300m Welsh P30list on Geoff Crowder’s v-g.me website under the invented and transposed name of Cantal Hill, with an accompanying note stating; Name from hall & wood to the West.
Cantal Hill | 380c | SO161725 | 136/148 | 200/214 | Name from hall & wood 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 Pen, Bryn or Moel in front of them or as in this instance transpose the name of a hall and wood and add the word Hill 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.

There has been a Significant Name Change to a hill that is listed in the Y Trichant – The 300m Hills of Wales, with the summit height, bwlch height and their locations, the drop and status of the hill derived from detail on contemporary maps produced from Ordnance Survey data.
The criteria for the list 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.

When the original 300m height band of Welsh P30 hills were published on Geoff Crowder’s v-g.me website this hill was not included in the Hills to be surveyed sub list, as it was considered not to meet the criteria then used for this sub category.
After the sub list was standardised, and interpolated heights and drop values also included the details for this hill were re-evaluated and it was listed under the name of Coed Foel-Dryll, which is a prominent name that appears near the summit of this hill on the contemporary 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 was entitled the Interactive Coverage Map, and the interactive mapping on the Magic Maps and WalkLakes websites, and it is the Ordnance Survey series of Six-Inch maps that give the name of Foel Dryll for this hill.
