Mapping Mountains – Significant Name Changes – 200m Twmpau

Stingwern Wood (SJ 145 000) 

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 a Trimble GeoXH 6000 survey conducted by Myrddyn Phillips. 

Stingwern Wood (SJ 145 000)

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 Carnedd Wen group of hills which are situated in the south-eastern part of North Wales (Region A, Sub-Region A4), and it is encircled by minor roads with the B4390 road further to its north, the B4389 road further to its west and the A483 road further to its south-east, and has the village of Aberriw (Berriew) towards the east. 

The qualifying hill appeared in the original 200m Welsh P30 list on Geoff Crowder’s v-g.me website listed at SJ 154 997 and under the invented and transposed name of Pen Cefnblewog, with an accompanying note stating; Name from buildings to the East.

Name from buildings 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.  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. 

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

The qualifying summit of this hill has now been confirmed and relocated from its originally listed position and as the name Stingwern Wood appears close to the relocated summit on the contemporary Ordnance Survey 1:25,000 Explorer map, and as this name is applicable to the wood where the summit of this hill is situated, this is an appropriate name to use for listing purposes for this hill. 

Therefore, the name this hill is now listed by in the 200m Twmpau is Stingwern Wood, and this was derived from the Ordnance Survey 1:25,000 Explorer map.
