Mynydd Coch (SH 804 099)
This is the twenty 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 13th May 2015.
The hill is part of the Bryniau Dyfi, which is a group of hills situated in the south-western part of north Wales. The hill is positioned between the small communities of Aberllefenni to its west and Aberangell to its east and is enclosed by the Dyfi Forest to its north, south and east.

The hill appeared in the 400m P30 list on Geoff Crowder’s v-g.me website under the name Mynydd Cwmcelli, this listing of hills is now co-authored with Aled Williams and known as Y Pedwarau. The name of Mynydd Cwmcelli appears on the Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map approximately 1 km west north-westward from this hill’s summit and is consistently placed on Ordnance Survey maps applicable to a 408m map heighted hill at SH 795 101.

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. As the 408m map heighted hill seemed of little consequence and was not then listed the use of its name for another hill did not seem inappropriate. 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.
Since publication of these P30 lists on Geoff Crowder’s v-g.me 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. One of the historical maps now available is the Ordnance Survey Draft Surveyors map which formed the basis for the first publicly available Ordnance Survey One-Inch ‘Old Series’ map. In the case of this hill it was Aled who conducted extensive research and studied the Draft Surveyors map in conjunction with other maps relating to land boundaries that necessitated the change in this hill’s listed name.
