This part of the Mapping
Mountains blog is dedicated to any hill reclassification for the listings I
have compiled. These include ones found
from map detail as well as those from accurate surveying.
There have been a number of
recent new entries to the Welsh 200m P30 list, including some that do not
appear on other P30 listings. The
following are those for Y Berwyn:
Y Berwyn Y Foel 258m
SH 993 117
A promotion from the sub-list as the summit spot
height on Ordnance Survey maps is 258m and the height of the bwlch is estimated
as c 227m (bwlch contouring between c 220m – c 230m), giving a drop of c
31m. The hill was originally listed as
Foel, the definite article ‘Y’ has now been added.
There have also been a number
of ‘new’ subs that have entered the Welsh 200m P30 listing for Y Berwyn, these
are:
Y Berwyn Bachrug c 292m
SJ 138 150
This hill has an estimated summit height of c 292m,
with an uppermost summit contour of c 290m.
It has a spot height of 263m on the area of its bwlch on the Ordnance
Survey enlarged Geograph map, giving a drop of c 29m. An ideal hill to survey with the Trimble for
P30 status.
Y Berwyn Pt. 209m 209m
SJ 163 254
Another hill that uses the Pt. notation as no
suitable name has been found for it by the blog author. The summit has a 209m spot height and with
bwlch contouring between c 180m – c 190m, with an estimated bwlch height of c
27m. It means this hill qualifies for
the Sub-list with an estimated drop of c 27m.
Y Berwyn Coed Lletty-yr-eos 248m
SJ 132 207
As the uppermost and opposing bwlch contours are
relatively close on the valley to valley traverse, the height of the bwlch has
been estimated as c 223m (bwlch contouring between c 220m – c 230m). And with a summit spot height of 248m, this
gives the hill c 25m of drop.
Y Berwyn Pt. 238m 238m
SJ 129 193
The summit and bwlch of this hill both possess a
spot height, 238m and 216m respectively.
This gives the hill a drop of 22m.
The Pt. notation is used as no name is known for the hill by the blog
author.
Y Berwyn Pt. 213m 213m
SJ 214 218
As the blog author does not know an appropriate
name for this hill the Pt. notation is being used. The summit has a 213m spot height and the
bwlch has a 191m spot height on the Ordnance Survey enlarged Geograph map. Although the latter spot height is not
centred, its position is acceptable, giving the hill 22m of drop.
Y Berwyn Berwyn 236m
SJ 207 224
The 236m summit height is taken from the Ordnance
Survey 1:25,000 map, and with bwlch contouring between c 210m – c 215, with an
estimated height of c 214m, it gives this hill a drop of c 22m. The name of Berwyn is positioned near to the
summit of this hill on larger scale Ordnance Survey maps. However, there is a farm placed at SJ 205
222, that this name may apply to.
Y Berwyn Pt. 212m 212m
SJ 112 135
With a 212m summit spot height, and a 191m bwlch
spot height on the Ordnance Survey enlarged Geograph map, this hill has 21m of
drop. As no appropriate name is known
for the hill the Pt. notation has been used.
Y Berwyn Chirk Castle c 212m
SJ 268 381
Excellent news – you can go to Chirk Castle and bag
a Sub hill! The summit of this hill is
somewhere in the confines of Chirk Castle, it could well be in the tea
room. The bwlch contouring is between c
190m – c 195m and is estimated as c 191m, giving the hill c 21m of drop. I wonder if the Trimble would pick up data in
a tea room?
Y Berwyn Pt. 298m 298m
SJ 032 139
Another hill name that uses the Pt. notation. The summit has a 298m spot height and the
bwlch height is estimated as c 278m at SJ 024 140, giving a drop of c 20m.
Y Berwyn Pt. c 291m c 291m
SJ 067 162
The summit height has been estimated as c 291m as
the hill has a small uppermost c 290m ring contour. The bwlch has a 271m spot height at SJ 063
159 on the Ordnance Survey enlarged Geograph map, giving this hill a drop of c
20m.
Y Berwyn Green Hall Hill 256m
SJ 156 192
With a summit spot height of 256m and an estimated
bwlch height of c 236m, based on bwlch contouring of c 230m – c 240, this hill
has c 20m of drop.
