Mapping Mountains – Significant Name Changes – Y Trichant – The 300m Hills of Wales

 

Pt. 310.4m (SH 677 201) 

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 13^th May 2017.

The hill is adjoined to the Y Llethr group of hills, which are situated in the western part of North Wales (Region A, Sub-Region A2), and it is positioned with minor roads to its west south-west and east, and the A496 road to its south, and has the small community of Bontddu towards the south south-west. 

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.

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.

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. 310.4m) 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. 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.
