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

 

Pt. 387.9m (SN 854 382) 

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 detail on contemporary maps produced from Ordnance Survey data and subsequent 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, and the Introduction to the Mapping Mountains publication of the list appearing on the 1^st January 2022.

The hill is adjoined to the Mynydd Epynt group of hills, which are situated in the central part of South Wales (Region B, Sub-Region B1), and it is positioned with minor roads to its south south-west and east, the A483 road to its west and the A40 road to its south, and has the town of Llanymddyfri (Llandovery) towards the west 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 Bryn Cefn-blewog, with an accompanying note stating; Name from buildings to the South-West.

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.  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. 387m) 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. 387.9m, 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.
