Mapping Mountains – Significant Name Changes – Y Pedwarau


Cwm Cynydd Bank (SO 061 726)

This is the fifty first 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 18th February 2016.

The hill is part of the group of hills associated with Pegwn Mawr, this range of hills is situated in the north-eastern part of Mid and West Wales.  The hill is positioned to the north north-east of the small community of Abaty Cwm Hir (Abbey Cwmhir) and its summit is embedded in forestry.

The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website under the name of Waun Gaseg, which is a name that appeared close to the summit of the hill on Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps of the day.  This listing of hills is now co-authored with Aled Williams and known as Y Pedwarau, and its height and drop were surveyed with the Trimble GeoXH 6000.

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 Waun Gaseg is such an example as this name has usually been applied by the Ordnance Survey to land beside a small stream that is below and to the south-east of this hill’s summit, whilst a number of different scaled Ordnance Survey maps position the name Cwn-cynydd Bank as applicable to land extending toward the summit of this hill. 

Extract from the series of Ordnance Survey Six-Inch maps

The name this hill is now listed by in Y Pedwarau (Europeaklist May 2013 and Haroldstreet January 2014) is Cwm Cynydd Bank and this was derived from a number of different scaled Ordnance Survey maps that place this name applicable to land that extends toward this hill’s summit.


The full details for the hill are:


Group:  Pegwn Mawr

Name:  Cwm Cynydd Bank

Previously Listed Name:  Waun Gaseg 

Summit Height:  454.9m

OS 1:50,000 map:  136, 147
