Pt. 316.5m (SN 713 634)
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, and the Introduction to the Mapping Mountains
publication of the list appearing on the 1st January 2022.
Y Trichant - The 300m Hills of Wales by Myrddyn Phillips |
The hill is adjoined to the Esgair Wen group of
hills, which are situated in the central
part of South Wales (Region B, Sub-Region B1), and it is positioned with the B4343 road to its north-west
and a minor road to its south, and has the town of Tregaron towards the
south-west.
The hill appeared in the original 300m height band of Welsh P30 hills published on Geoff Crowder’s v-g.me website, under the
invented and transposed name of Banc Bwlchyddwyallt,
with an accompanying note stating; Name
from buildings to the South-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 farm and add the word Banc 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.

However, on occasion 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. 316.5m) 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. 316.5m, 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.
