Mapping Mountains – Significant Name Changes – 100m Twmpau

Coed Gaer (SH 799 808)

This is the forty fourth 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 16th January 2016.

The hill is part of the Rhos group of hills, this range of hills 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 website under the partly invented name Pen Coed Gaer, with an accompanying note stating; Name from wood at summit.  The listing this hill is now a part of is named Twmpau (thirty welsh metre prominences and upward) and its height was confirmed by the survey with the Trimble. 

Pen Coed Gaer
    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 add the word Pen.  This is not a practice that I now advocate as with a little 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 current Ordnance Survey 1:25,000 Explorer maps, the use of the invented and prefixed word of Pen is wholly unnecessary, therefore the name this hill is now listed by in the Twmpau is Coed Gaer.

The full details for the hill are:

Group:  Rhos

Name:  Coed Gaer

Previously Listed Name:  Pen Coed Gaer 

Summit Height:  134.0m (converted to OSGM15)
