Craig y Garreg Lwyd (SH 730 427) – 400m Sub-Pedwar reinstated
to Pedwar
There has been a reclassification to the listing of Y Pedwarau due to a survey with a Leica
GS15 conducted by John Barnard and Graham Jackson. Y
Pedwarau is the title for the list of 400m hills of Wales and takes in all
Welsh hills at or above 400m and below 500m in height that have a minimum 30m
of drop, the list is a joint compilation between Myrddyn Phillips and Aled
Williams and it commenced publication on Mapping Mountains on the 30.01.17.
Accompanying the main Y
Pedwarau list are five categories of sub hills, with this hill being
reclassified from the 400m Sub-Pedwar category. The
criteria for 400m Sub-Pedwar qualification is all Welsh hills at or above 400m and
below 500m in height that have 20m and more and below 30m of drop.
The name of the hill is Craig y Garreg Lwyd and prior
to the survey with the Leica GS15 the hill was listed with 29.9m of drop based
on a 473.4m (converted to OSGM15) summit and 443.5m (converted to OSGM15) bwlch
height ascertained from a survey with the Trimble GeoXH 6000 and which resulted
in this hill’s reclassification from a Pedwar
to a 400m Sub-Pedwar.
Craig y Garreg Lwyd is situated in the Arenig range of hills
with its Cardinal Hill being Graig Goch (SH 751 447) and is placed in the
Region of North Wales (Region A, Sub-Region A3). The hill is positioned overlooking the B 4391
which is to its south, with the communities of Llan Ffestiniog to the west
south-west and Blaenau Ffestiniog to the north-west of the hill.
The hill is a part of designated open access land and can be
accessed either from its south-west, south or south-east where tracks make
their way toward the lower part of the hill.
However, the hills surrounding Craig y Garreg Lwyd are recommended to
visit and so combining it with its near neighbours is worthwhile.
The survey with the Leica GS15 resulted in a summit height of
473.8m and a bwlch height of 443.6m, with these values giving this hill 30.2m
of drop, which is sufficient for it to be re-instated as a Pedwar.
