Due to the nature of
Twyn y Waun the hill received a new category of classification in January 2018;
the newly created title was one of Dual Summit Pedwar. The reason for doing this is that the natural
summit of this hill is intact, however it is so inconspicuous compared to what
now towers over it that on my previous visit I walked over it twice without
realising it was the actual natural summit.
What now towers over the
natural summit is the end product of mining waste spoil, which in this area has
created three new man-made Pedwar hills and as of June 2023 a newly discovered
400m Sub-Pedwar. The three Pedwar hills
are huge and from a distance look almost natural. When Aled and I created the category of Dual
Summit Pedwar for Twyn y Waun it was with intention to recognise an ascent of
the natural and/or adjacent man-made summit as counting toward a completion of
the Y Pedwarau. Today’s objective was to
visit the natural summit as the others are obstructed by copious amounts of
barb wired fences and time was also now against us as we wanted a meal on our
way back toward Welshpool.
The natural summit of
Twyn y Waun can easily be visited from an open gate beside a cattle grid, close
to the high point of the minor road that skirts this and the other man-made
hills to their east.
We parked in a lay-bi
and sauntered back down the road to the gate giving access to the open
hillside, which hereabouts is a grazing field used by the customary sheep, but
also inhabited by many mountain ponies which were here on my last visit and
which today were there in great numbers, with their young looking ever so cute
in the evening light as the sun cast beautiful colour on the scene.

I followed Mark through
the open gate and up toward the ponies who were all gathered around the summit
of the hill. Once on top I used the
Trimble as a hand-held unit to zero in to the ten figure grid reference attained
from LIDAR analysis for the high point of the hill.

As the equipment quietly
beeped away collecting its individual datum points Mark walked toward the point
of the ten figure grid reference given on the Hill Bagging website for the
summit. Visually I found these two
positions hard to separate, although Mark thought the LIDAR position a little
higher.

Once I had packed the
equipment away I joined Mark and we slowly walked down the hill toward the
connecting bwlch of the two Twyn y Waun man-made hills (SO 082 070 and SO 085
065). Again, the area of the bwlch was
heavily guarded by barbed wire, turning our back to the hills for another day
we headed to the open gate and the minor road leading back to the awaiting car.

It had been a fine day
on the hill with five new Pedwar hills visited for Mark, and three for me with
a fourth being a repeat. All that
remained was the drive to the Wheelright Arms in Erwyd for a good bit of pub
grub!
