Mapping Mountains – Significant Name Changes – 100m Twmpau and Y Trechol - The Dominant Hills of Wales


Coed Gaer (SH 799 808)

There has been a Significant Name Change to a hill that is listed in the 100m Twmpau and Y Trechol - The Dominant Hills of Wales; and the following details are in respect of a hill that was surveyed with the Trimble GeoXH 6000 on the 16th January 2016.

The criteria for the two listings that this name change applies to are:

100m Twmpau - All Welsh hills at and above 100m and below 200m in height that have 30m minimum drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.

Y Trechol - The Dominant Hills of Wales - These are the Welsh P30 hills whose prominence equal or exceed half that of their absolute height.  

The hill is a part of the Rhos range, this group of hills includes Moelfre Uchaf and is an extension of Mynydd Hiraethog and is situated in the northern part of Wales.  The hill is positioned between the south-eastern outskirts of Llandudno to its north-west and Penrhyn Bay to its north-east.

The hill appeared in the 100m P30 list on Geoff Crowder’s v-g.me website under the partly invented name Pen Coed Gaer, with an accompanying note stating; Name from wood at summit.

    Two points of same height - other at SH799808. Name from wood at summit.
     
 
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, use the name of the wood near to the summit of the hill and prefix it with the word Pen.  This is not a practice that I now advocate as with research either conducted locally or historically an appropriate name for the hill can usually be found.   

Extract from the Ordnance Survey 1:25,000 Explorer map

As an appropriate name for this hill already exists on Ordnance Survey 1:25,000 Explorer maps, the use of the invented and prefixed word of Pen is unnecessary, therefore the name this hill is now listed by in the 100m Twmpau and Y Trechol - The Dominant Hills of Wales is Coed Gaer.



The full details for the hill are:
