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

 

Glog (SJ 114 037) 

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. 

Glog (SJ 114 037)

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.

The hill is adjoined to the Carnedd Wen group of hills which are situated in the south-eastern part of North Wales (Region A, Sub-Region A4), and it has the B4385 road to its north, the B4389 road to its west, the B4390 road to its south and the B4385 road to its east, and has the small town of Llanfair Caereinion towards the north north-west. 

The hill appeared in the original Welsh 300m P30 list published on Geoff Crowder’s v-g.me website, under the transposed name of Manafon-llys, which is a prominent name that appears close to this hill’s summit on contemporary Ordnance Survey 1:25,000 Explorer maps.

During my early hill listing I paid little regard to name placement on the 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 either inappropriate or where another name is viewed as being more appropriate.

When I first visited this hill in October 2011 I drove to the farm positioned north-west of the summit and asked permission to park.  I met Mr Roberts who kindly let me leave my car in the farmyard and when I asked if I could walk up the hill from this direction, he said ‘well, that’s that then’. 

I also asked Mr Roberts what name he knew the hill by, he said Glog, which is also the name of his farm.  This name is substantiated by map evidence as the farm positioned at SJ 115 033 is named Tan-y-glog.  The word glog can be translated as knoll and the word tan as below, therefore Tan-y-glog can be translated as below the glog, or below the knoll and this is exactly where this farm is situated.  With the name Manafon-llys being that of a township which except for this hill being situated in it, has nothing whatsoever to do with the hill itself, as evidenced by the plan of the parish of Manafon given below.

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