Mynydd Fynnon Wen (SN 726 793)
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 LIDAR analysis
conducted by Myrddyn Phillips.

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 with the A44 road to its north and the
A4120 road to its south and east, and has the village of Ponterwyd towards the
east north-east.

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 Mynydd
Pant-yr-oerfa, with an accompanying note stating; Name from buildings 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 put the word Mynydd in
front of a farm 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 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 old Vector Map Local that used to be hosted on
the Geograph website and which was entitled the Interactive Coverage Map, and
it is the series of Six-Inch maps that name the land taking in the summit of
this hill as Mynydd Fynnon Wen.

Therefore, the name this hill is
now listed by in the Y Trichant – The 300m Hills of Wales is Mynydd Fynnon Wen, and this was derived from the Ordnance Survey series
of Six-Inch maps.
