Mapping Mountains – Significant Name Changes – Y Trichant – The 300m Hills of Wales

Top Field (SO 114 890) 

There has been a Significant Name Change to a hill that is listed in the Y Trichant – The 300m Hills of Wales, 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. 

Top Field (SO 114 890)

The criteria for the list that this name change applies to are: 

Y Trichant – The 300m Hills of Wales.  Welsh hills at or above 300m and below 400m in height that have 30m minimum drop, with an accompanying sub list entitled the Sub-Trichant with the criteria for this sub category being all Welsh hills at or above 300m and below 400m in height with 20m or more and below 30m of drop.  The list is authored by Myrddyn Phillips, with the Introduction to the list and the renaming of it appearing on Mapping Mountains on the 13^th May 2017. 

Y Trichant - The 300m Hills of Wales by Myrddyn Phillips

The hill is adjoined to the Cilfaesty group of hills, which are situated in Mid and West Wales (Region B, Sub-Region B1), and it is positioned with minor roads to its west, south and east and the A483 road farther to its north-west, and has the town of Y Drenewydd (Newtown) towards the north.                     

The hill appeared in the original 300m Welsh P30 list on Geoff Crowder’s v-g.me website under the transposed name of Blackhill, which is a prominent name adjoined to a farm that appears on the contemporary Ordnance Survey 1:25,000 Explorer map.

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 or as in this instance transpose the name of a farm and use it for that of the hill.  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.

After visiting the summit of this hill I called at the large chicken shed adjoined to Blackhill farm where I met a young man operating a forklift.  I enquired about the hill which was just behind us and explained my interest in its name.  He couldn’t help but said that his boss was due back soon and he could give him a ring if I wanted.  Yes please was my reply!  I then spent a few minutes on the phone talking to Prosser James; the farmer from Blackhill who told me he did not know an individual name for the hill but its upper field where the summit is situated is known as Top Field. 

Therefore, the name this hill is now listed by in the Y Trichant – The 300m Hills of Wales is Top Field and this was derived from local enquiry.
