Bryn Llwyd (SN 835 920) - Pellennig addition
There has been a new hill that has entered the list of Y Pellennig – The Remotest Hills of Wales, due to a recent Trimble survey. The hill is situated in the Pumlumon group of hills in the northern part of mid Wales and is situated between the towns of Llanidloes to its south-east and Machynlleth to its north-west.
There has been a new hill that has entered the list of Y Pellennig – The Remotest Hills of Wales, due to a recent Trimble survey. The hill is situated in the Pumlumon group of hills in the northern part of mid Wales and is situated between the towns of Llanidloes to its south-east and Machynlleth to its north-west.
The hill was surveyed over two days on 5th
and 13th May 2016, both in beautiful sunshine and its name is Bryn Llwyd. It can be accessed from the
east via a track that leaves a minor road toward the farm of Nant-yr-hafod, or
alternatively it can be accessed from its north via a track that leaves a minor
road leading toward the lake of Glaslyn, or from a track that leaves the same
minor road and makes its way around the southern flank of Y Grug. These approaches from the north have to
contend with Cors yr Ebolion, which as its Welsh name suggests is a bog. If tempted by one of these northern
approaches it is advisable to keep to a path that contours the eastern flank of
Banc Bugeilyn before losing height to cross the reed infested stream close to
the south-west corner of the conifer plantation to the north of this hill’s
summit.
Bryn Llwyd was surveyed by the Trimble GeoXH
6000 as being 501.4m (converted to OSGM15, and average of four summit surveys) high, and prior to this survey the highest point listed
hereabouts was Bryn yr Ŵyn which
had been regarded as being higher than Bryn Llwyd and therefore listed as
the summit in the 500m Twmpau list.
However, Bryn yr Ŵyn was surveyed
by the Trimble as being 499.9m (converted to OSGM15, and average of five summit surveys) high, and as contour interpolation and a
rudimentary survey suggested that the connecting bwlch between these two hills was
not low enough to give each sufficient drop to be listed as separate summits;
only Bryn yr Ŵyn was
previously listed. This Trimble survey
confirms Bryn Llwyd to be the higher summit (see Summit Relocation post)
and as the nearest paved public road at SN 84696 94288 is 2.525km from the
summit this hill qualifies for the listing of Y Pellennig – The Remotest Hills
of Wales, having the required 15m minimum drop and 2.5km minimum distance
between the summit and the nearest paved public road.
This now brings the overall total for Y Pellennig to 168
hills for the Complete list (All Wales), with the total for the Mainland Wales
list being 124 hills. The Master List
will be duly updated on the Mapping Mountains site.
The full details for the hill are:
Cardinal Hill: Pumlumon Fawr
Summit Height: 501.4m (converted to OSGM15, and average of four summit surveys)
Name: Bryn Llwyd
