Pt. 259m (SJ 181 438) – Lesser Dominant addition
There has been an addition to the listing of Y Trechol – The Dominant Hills of Wales which has resulted in this hill being added to the Lesser Welsh Dominant list. The criteria for inclusion in this category of sub list is those P30 hills whose prominence is 33% or more and below 50% of their absolute height.
The details relating to this hill’s inclusion as a Lesser Welsh Dominant are retrospective as it appeared in the Y Berwyn group of hills when published on the Mapping Mountains site on the 3rd March 2017.
The hill did not appear in the original listing of Y Trechol – The Dominant Hills of Wales as it was listed with an estimated c 86m of drop, and when coupled with its 259m summit spot height that appeared on the Ordnance Survey 1:25,000 Explorer map it gave this hill 33.20% Dominance, which was just under the minimum required to be classified as a Lesser Welsh Dominant hill.
The hill is listed in the Y Berwyn group and is placed in the Region of North Wales (Region A, Sub-Region A4) with its Cardinal Hill being Moel Fferna (SJ 116 397), and is almost encircled by the Afon Dyfrdwy (River Dee) and is situated with the town of Llangollen to the east south-east.
If wanting to visit the hill the upper section is a part of designated open access land and it can be easily accessed from a track that leaves the A5 road which is positioned to the south of the summit.
The hill is being listed under the point (Pt. 259m) notation as I do not know an appropriate name for it either from local enquiry or historical research, and it qualifies for Lesser Welsh Dominant status based on a re-interpolation of its bwlch height which gives the hill a drop of 87m and a Dominance of 33.59%.
