Carreg Wen (SH 762 583)
There has been a Significant Name Change to a hill
that is listed in the Y Trichant,
with the summit height and its location derived from a spot height and the
bwlch height, its location and the drop of the hill confirmed by LIDAR analysis
conducted by Myrddyn Phillips.

The criteria for the list that this name change applies to
are:
Y Trichant – 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 is adjoined to the
Carneddau group hills which are situated in the north-western part of North
Wales (Region A, Sub-Region A1), and it is positioned with the A5 road and the
Afon Llugwy to its south, and has the village of Capel Curig towards the east
and the village of Betws-y-coed towards the east south-east.
The hill originally
appeared in the 300m P30 list on Geoff Crowder’s v-g.me website under the partly
invented and transposed name of Pen Llyn
Bodgynydd, with an accompanying note stating; Name from lake to the North.
Pen Llyn Bodgynydd | 327m | SH762583 | 115 | 17 | Name from lake 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 Pen, Bryn or Moel in front of them or as in this instance, use the name of a lake
and put the word Pen in front of
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.

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 formed the basis for the change in this hill’s listed
name.

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, it is this map that shows the name
of Carreg Wen as applicable to this hill.
Therefore, the name this hill is now listed by in
the Y Trichant is Carreg Wen, and this
was derived from the Ordnance Survey Draft Surveyors map.
