Mapping Mountains – Significant Name Changes – Y Pedwarau

Weston Bank (SO 199 702)

This is the fifty seventh 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 8th April 2016.

The hill is part of the group of hills associated with Fforest Glud, this range of hills is situated in the eastern part of Mid and West Wales and are known as the Radnor Forest in English.  The hill is positioned between the small communities of Llangunllo to the north-east and Bleddfa to the south south-east.

The hill appeared in the 400m P30 list on Geoff Crowder’s website under the name of Pen-y-clawdd Hill, which is a name that appeared close to the summit of the hill on Ordnance Survey 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 the height and status of the hill was confirmed by the survey with the Trimble. 

Pen-y-clawdd Hill

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 Pen-y-clawdd Hill is such an example as this name has been consistently applied on the Ordnance Survey maps that endeavour to use appropriate name placement to a c 401m high hill that stretches from SO 193 705 to land taking in a c 400m rise at SO 190 702.  The land of Pen-y-clawdd Hill is considered separate from that of the land associated with the hill that this blog post relates to.

Appropriate name placement for Pen-y-clawdd Hill on the Ordnance Survey 1:25,000 historical map

Since publication of these P30 lists on Geoff Crowder’s website there have been a number of Ordnance Survey maps made available online, some of these are historical such as the series of Six-Inch maps on the National Library of Scotland website, whilst others are current and digitally updated such as the enlarged map on the Geograph website.  Two of the historical maps now available are the Ordnance Survey Draft Surveyors map which formed the basis for the Ordnance Survey One-Inch ‘Old Series’ map, and it was the former of these maps that name the hill as Weston Bank.

Therefore the name this hill is now listed by in Y Pedwarau (Europeaklist May 2013 and Haroldstreet January 2014) is Weston Bank and this was derived from the Ordnance Survey Draft Surveyors map.
