Moel y Penmaen (SH 338 386) - Lesser Dominant addition
There has been an addition to the listing of Y Trechol – The Dominant Hills of Wales which has resulted in the hill being added to the Lesser Welsh Dominant list. The criteria for inclusion in this category of sub list is those Welsh 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 hill are retrospective as it appeared in the Pen Llŷn group of hills when published on the Mapping Mountains site on the 11th February 2016.
The hill did not appear in the original listing of Y Trechol – The Dominant Hills of Wales even though the details on the then current Ordnance Survey maps showed a 153m summit spot height and bwlch contours between 90m – 100m, with an estimated bwlch height of c 92m giving a drop of c 61m and a Dominance of 39.87% which is sufficient for inclusion into the Lesser Welsh Dominant list.
The hill is listed in the Pen Llŷn group and is placed in the Region of North Wales (Region A, Sub-Region A1) with its Cardinal Hill being Garn Ganol (SH 364 447), and it is situated between the small communities of Boduan to the south-west and Llannor to the south-east.
If wanting to visit the hill a track to the south-east which makes its way toward a small reservoir gives easy access to the upper part of the hill which is on open access land.
The name of the hill is Moel y Penmaen and it qualifies for Lesser Welsh Dominant status based on a 153m summit and a c 92m bwlch height, with these values giving this hill c 61m of drop and 39.87% of Dominance.
