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

Trwyn y Fuwch (SH 813 823)

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 overlooking the north Wales coastline and Ormes Bay which is also known as Llandudno Bay, and has the communities of Craigside to its west south-west and Penrhyn Bay to its south-east.

The hill appeared in the 100m P30 list on Geoff Crowder’s website under the name of Creigiau Rhiwledyn, which is a name that appeared close to the summit of the hill on Ordnance Survey maps of the day.

During my early hill listing I paid little regard to name placement on a map, or the meaning of names and to what feature the name was appropriately applied to.  Therefore I prioritised names for listing purposes that I now understand are inappropriate, and Creigiau Rhiwledyn is such an example as this name has been consistently applied by the Ordnance Survey to the cliffs that are positioned north-eastward of this hill’s summit, and although it can be appropriate to use the main named feature of a hill when naming it for listing purposes, in this instance the hill has its own name, and this is Trwyn y Fuwch.  In addition to its Welsh name the hill is also known by its English name of Little Orme.

Therefore the name this hill is now listed by in the 100m Twmpau and Y Trechol - The Dominant Hills of Wales is Trwyn y Fuwch, and this was derived from a number of sources including the Dictionary of the Place-Names of Wales (Hywel Wyn Owen and Richard Morgan, Gomer Press 2007).  

The full details for the hill are:
