Mapping Mountains – Significant Name Changes – Y Pedwarau

Foel Fawr (SN 900 904)

This is the 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 18th April 2014.

The hill is part of the Pumlumon range, which is an extensive group of hills situated in the north-western part of mid and west Wales, and is positioned between the small communities of Penffordd-las (Staylittle) to the north-west and Llawr-y-glyn to the east north-east, with the reservoir of Llyn Clywedog to the hill’s south.

The hill appeared in the 400m P30 list on Geoff Crowder’s website under the name Bryn yr Hwrdd, this name appears on the Ordnance Survey 1:25,000 map over 1 km north-westward from this hill’s summit and is consistently placed on Ordnance Survey maps applicable to land centred at SN 899 911.  This listing of hills is now co-authored with Aled Williams and known as Y Pedwarau.    

During my early hill listing I used the map name that appeared closest to the summit of the listed hill or which seemed most appropriate for the hill, without due consideration for its positional value, doing so can perpetuate the use of inappropriate names.  This is not a practice that I now advocate as with a little research either conducted locally or historically a more appropriate name for the hill can usually be found.

Bryn yr Hwrdd

The name this hill is now listed by in Y Pedwarau (Europeaklist and Haroldstreet 2013) is Foel Fawr, and this was derived from Ordnance Survey enlarged mapping that appears on the Geograph website.  This mapping became publicly available after the original P30 lists were published on Geoff’s website.

Since the publication of these P30 lists there have been a number of historical Ordnance Survey maps made available online, including the series of Six-Inch maps on the National Library of Scotland website, much of the place-name information on these maps were the source for what now appears on the Ordnance Survey enlarged mapping on the Geograph website.
