Mapping Mountains – Significant Name Changes – 200m Twmpau

Pt. 212.2m (SJ 304 530) 

There has been a Significant Name Change to a hill that is listed in the 200m Twmpau, 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 LIDAR bwlch analysis and a Trimble GeoXH 6000 summit survey conducted by Myrddyn Phillips.

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

200m Twmpau - Welsh hills at or above 200m and below 300m in height with 30m minimum drop, with an accompanying sub list entitled the 200m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 200m and below 300m in height with 20m or more and below 30m of drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.

The hill is adjoined to the Moel y Gamelin group of hills, which are situated in the north-eastern part of North Wales (Region A, Sub-Region A2), and it is positioned with the B5433 road to its north and minor roads to its west and south, and has the village of Bryn-teg towards the south. 

The hill appeared in the original Welsh 200m P30 list on Geoff Crowder’s v-g.me website, under the transposed and invented name of Moss Hill, with an accompanying note stating; Name from conurbation to the East.

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 transpose the name of a district and add the word Hill to it.  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. 212.2m) notation, and for this hill this is such an example. 

Therefore, the name this hill is now listed by in the 200m Twmpau is Pt. 212.2m, 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.
