Cefn Penarth (SN 924 853)
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 initially confirmed by Joe Nuttall who produced a summit analysis programme using LIDAR, and then by LIDAR
analysis initially conducted by Jim Bloomer and subsequently by Myrddyn
Phillips, with the hill previously surveyed with the Trimble GeoXH 6000.

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 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 Pumlumon group of hills, which are situated in the north-western
part of Mid and West Wales (Region B,
Sub-Region B2), and it
is positioned between the river valleys of the Afon Clewedog to its north and
the Afon Hafren (River Severn) to its south, and has a minor road running the
length of its ridge and the B4518 road to its north-east, and has the town of
Llanidloes towards the east south-east.
The hill appeared in the
original Welsh 300m P30 list on Geoff Crowder’s v-g.me website under the partly
invented and transposed name of Mynydd
Cefn-penarth, with an accompanying note stating; Name from buildings to the North-East and North-West.
Mynydd Cefn-penarth | 317m | SN925854 | 136 | 214 | Name from buildings to the North-East and 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 put the word Mynydd in
front of that of a farm. 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 the updating of this hill’s details I made
local enquiries relating to its name and was told that the area of land taking
in the ridge comprising this hill is known as Cefn Penarth.
Therefore, the name this hill is
now listed by in the Y Trichant – The 300m
Hills of Wales is Cefn Penarth, and this was derived from local enquiry.

hill are:
