Mapping Mountains – Significant Name Changes – Y Pedwarau and Y Trechol – The Dominant Hills of Wales


Cefn Digoll (SJ 264 058)

This is the seventy second post under the heading of Significant Name Changes, and the following details are in respect of a hill that was surveyed with the Trimble GeoXH 6000 on the 24th and 28th March 2017.

The hill is a part of the Cefn Digoll range, which is situated in the north-eastern part of Mid and West Wales (Region B, Sub-Region B1), and is positioned above the A 483 and the village of Trewern to its north and the town of Y Trallwng (Welshpool) to its west north-west.  

The summit of Cefn Digoll

The hill appeared in the 300m P30 list on Geoff Crowder’s v-g.me website under the name Beacon Ring, this is the name given to the summit area of the hill in English, with its Welsh counterpart being Caer Digoll.  The listing this hill is now a part of is named the Y Pedwarau (Welsh hills at or above 400m and below 500m in height with 30m minimum drop and co-authored; Myrddyn Phillips and Aled Williams ) and Y Trechol – The Dominant Hills of Wales (Welsh P30 hills whose prominence equal or exceed half that of their absolute height and authored; Myrddyn Phillips) and its height, drop and dominance was confirmed by a survey with the Trimble GeoXH 6000.

During my early hill listing I did not lay emphasis on prioritising a name for a hill over that for its summit, and therefore on occasion I used a summit name in preference to that of the hill name, and the use of Beacon Ring is a case in point as the hill is known in English as the Long Mountain.  This practice can be appropriate if the summit name is prioritised locally, otherwise for listing purposes it is customary to prioritise the hill name in preference to that of its summit.

Also during my early hill listing I thought it sufficient to use English or anglicised names for hills even if a Welsh name existed, this in the main is not a practice that I now advocate, especially if the Welsh name has historical evidence of use, and as the English names for this hill and its summit have Welsh counterparts, these being Cefn Digoll and Caer Digoll respectively, the hill name of Cefn Digoll is being used. 

Therefore the name this hill is now listed by in the Y Pedwarau and Y Trechol – The Dominant Hills of Wales is Cefn Digoll, as this is the Welsh name for the hill.
