Allt y Clych (SN 978 570), Lan Ganol (SN 973 571), Lan Fach (SN 971
574), Llethr Melyn (SN 959 579), Craigol (SN 979 587), Banc Craigol (SN 983
582) and Cefn Tŷ Mawr (SN 986 576)

Banc Craigol (SN 983 582)
|
When visiting five hills
amongst the Elenydd two days ago that were centred on Wenallt (SN 933 571) I
looked to my east and thought the ridges extending upto and away from Llethr
Melyn and Banc Craigol worth investigating.
And so, with the weather set fine for the day I parked beside the B 4358
at SN 983 566 where there is sufficient space for two cars to be left.
From this parking spot a
narrow lane heads into the Hirnant valley with hill ridges either side, it
would be this valley that formed the centre of my planned horseshoe walk. As I walked toward Allt y Clych the green
slopes of Banc Craigol and the wooded summit of Cefn Tŷ-mawr
rose across the intervening valley, both looked good hills and would be the
last two I visited later in the afternoon.

|
I left the lane after a
few hundred metres and gained access onto the higher slopes of Allt y Clych
through two gates leading across the hill’s lower fields. Once on the higher part of the hill the views
opened up and the ground steepened until I arrived at its attractive
summit. Two spots vie for the highest
point, one grassy and one with a small outcrop of rock, I gathered data from
both and waited lazily in the morning’s sunshine until the Trimble was packed
away.

Gathering data at the summit of Allt y Clych
|
Between the P30s of Allt
y Clych and Llethr Melyn are a number of small bumps, including Lan Ganol and
Lan Fach, I surveyed both of these hills including any alternate summit and
their respective bylchau, this took quite some time and by the time I reached
the path leading upto Craig Chwefri and its trig point I had taken nine data
sets.
|
Looking back to Allt y Clych - I'd taken nine data sets along this ridge
|
The path leading toward
the trig point petered out into hillsides of moor grass and bilberry, away to
my west was the forested top of Gornoeth which I had visited two days
previously, it felt a little odd being back in this area so soon after visiting
a number of its hills, but there are still more to investigate and these
southerly approaches to some of the lower hills of the Elenydd are proving pleasantly
tranquil.
The summit of Craig Chwefri
is part of the slightly higher hill of Llethr Melyn which according to Ordnance
Survey data has three summits of the same 433m map height. As I reached the trig and placed the Trimble
to gather data on the highest ground a few metres away from it, I looked out to
these three tops of Llethr Melyn and thought the furthest easterly one to look
slightly higher, however the human eye is deceptive when judging the lay of
land and only a survey would be able to separate them by height.

|
By now patches of cloud
had built in the sky which added light and shade to the landscape, this in time
would bring succulent summer greys to the eastern land that was enriched with
direct sunlight, this is always a treat and gives a vivid appeal to
photography, but this was for later in the day, now I wanted to survey the
three tops of Llethr Melyn and shortly after leaving the trig point on top of
Craig Chwefri I arrived at the first rocky top.
I checked the ten figure
grid reference from the Ordnance Survey enlarged Geograph map and found it
directing me to the lower of two rocky outcrops about thirty metres apart, I
took data from both and then proceeded to the other two map heighted 433m
summits, both of these are on moorland.

|
Happy that four data
sets and an additional one from beside the trig on Craig Chwefri was sufficient
I packed the Trimble away and walked along the hill’s easterly ridge, before
delving down northward toward the hill’s connecting bwlch with higher ground.

|
After collecting data
from two places on the hill to hill traverse on this bwlch I considered that
the second part of the walk was nearing its conclusion, the first having been
the ridge from Allt y Clych to just beyond Lan Fach, the third and last section
would take me over the three P30s of Craigol, Banc Craigol and Cefn Tŷ-mawr.
|
Gathering data at the bwlch of Llethr Melyn
|
I lost a little height
and contoured through what could have been decidedly boggy ground on a small
path that led toward green fields which constituted the highest part of this
valley’s cultivation. Once beyond the fields
I joined a track that led to the old farm house of Lluestnewydd where Maj and
Stewart Jackson-Carter were busy inspecting their large stone barn’s roof. I waved as I approached and soon we were in
conversation, shortly afterward Maj said some magical words ‘would you like a
cup of tea’. Mmmmmmmmmm heaven on earth
does exist!
As Maj went inside to
get the tea brewing, Stewart opened the gate and we sat beside their ornamental
pool and chatted, when Maj appeared with a tray of mugs full of tea I had to
smile and then found it hard to stop.
|
Heaven on earth - Maj brings the mugs of tea
|
It was lovely meeting
Maj and Stewart, we talked for quite some time about the local hills, their
house and its history, the Trimble and surveying, the route I had taken to get
here and my onward route back to my car, their meetings with other walkers who
occasionally come this way, fox hunting, place-names and probably a multitude
of other topics.
|
With Stewart and mugs of tea at Lluestnewydd
|
Throughout the
conversation I supped on my mug of tea and relaxed and happily smiled away, the
tea was an absolute luxury and one that was totally unexpected. After about twenty minutes I thanked them and
we said our goodbyes and I wandered off to continue my route, this time in a
southerly direction toward the next three hills.
|
Cheers - many thanks to Maj and Stewart for my refreshing pit stop. Allt y Clych is in the background on the right and the summit of Banc Craigol on the far left of photo
|
The track from
Lluesnewydd led toward another farm named Craigol with the right of way
swinging leftward to miss the farm yard, this now led me down toward the next
bwlch I wanted to survey, this is to the north of the rocky summit of Craigol
which sprung up with its upper slopes now showing the signs of felled forestry,
but thankfully no re-planting had taken place.
Once I had wandered
around in the field where the bwlch lay for a number of minutes and picked the
spot for the Trimble to gather its data, I stood and regained by breath for the
next ascent up to the unusually rocky summit of Craigol.

|
On my way up to the
summit I bi-passed a group of cows with their calves that were wandering down
the track and stopping for a contented graze, once across a fence I was in the
remains of the felled forestry. The high point of Craigol has a small ridge
leading to a steep outcrop of what I thought to be mudstone, all layered on top
of itself and looking unusually out of place amongst hills of moor and grassy field.

|
The next survey was at
the bwlch between the summits of Craigol and Banc Craigol, it was also the survey
that I was most concerned about as it looked as if it was situated in a filed
adjacent to a farm house. As I arrived
at the farm I knocked on the front door with good intention of introducing myself,
explaining my unusual surveying hobby, trying to explain what prominence is and
the necessity for them to give me permission to survey their field, and who
knows I may have ended up with another cup of tea in the process.

Lines of hill and pasture
|
Unfortunately no one
answered so I sneaked around the farm yard, quietly went through a gate and
followed a track to where the critical bwlch lay, all in full view of the
house. Once I had picked the spot for
Trimble placement I stood beside another gate and hoped that no one would ask
what I was doing. It didn’t help that
the bwlch lay just below a grassed bank which interfered with satellite
reception, so it took quite some time for the 0.1m accuracy to be attained
before data can be logged. Once complete
I quietly retraced my steps and continued up the right of way to the easterly
slopes of my next hill.

|
Banc Craigol is an
appealingly shaped hill with an elongated summit ridge that extends from its
grassy top in a south-westerly direction to a slender ridge crest before
plunging down through slopes of bracken to the Hirnant below. As I arrived at its summit the day’s
exertions were taking their toll and I gratefully rested as the Trimble gathered
its data, only two surveys now remained.

The afternoon was now
enhanced with deep grey cloud out to the east which illuminated the richness of
colour with the late afternoon sun in the west, and as I re-joined the right of
way down to the next connecting bwlch I stopped and admired a single well
shaped tree in a brightly coloured green field as deep colour behind faded into
shadow.

Summer colour on a single tree
|
Once the last bwlch
survey was complete I plodded up toward the summit of my last hill of the day,
this summit is part of Coed Tŷ Mawr and has the name of Cefn Tŷ Mawr, with the farm
that the hill and wood take their name from to the south of the summit, the
north-easterly flank and upper part of this hill has an oak wood on it, today
the wood was filled with Bluebells and once across a fence I delicately walked
up to the large boulder at its high point.

|
After I had stood on top
of the boulder I placed the Trimble with its internal antenna aligned to the
highest part of it and then started a long wait. I suspected this would happen as tree
coverage is not ideal for satellite reception.
However, I found a comfortable rock to sit on which was covered in moss
and only four paces away from the sides of the boulder, so I could briskly
march up to the boulder and step up to check on the Trimble’s downward progress
to the 0.1m accuracy level.

|
The initial part of my
long wait was welcome as I sat and ate a bean burger that I had cooked the
previous day, munched on a couple of sandwiches and immersed myself in the life
of the wood as bird song radiated out.
After a while I found that I was studying the colours of the near trees
and examining the ground to my north-east which looked horrendously brambled, I
had already torn my leg on one of these brambles and caused copious amounts of
blood to trickle out of the wound, trying to wipe this with a clump of grass
only smothered it all over my leg which now looked as if I had been stabbed!

|
After thirty minutes I
wondered how much longer I would have to wait and life in a wood began to tax
my patience. After 45 minutes I had
lapsed into a contented otherworldly experience as an occasional flash of sunshine
penetrated the wood and gave dabbled light to the undergrowth.
|
I'd been in the wood so long that I started to enjoy the pattern the trees made with the sky
|
|
Only the occasional sunburst penetrated the cloud as I waited patiently in the wood
|
After 55 minutes I
wondered if I should at least activate the Trimble and gather data until it
screeched, which is the sign that data collection should cease. I jumped up from my slumber and pressed ‘Log’
and turned the equipment off after it had gathered 133 points which is more
that the recommended minimum.
By the time I had taken
photos of the Trimble positioned on the boulder I had been in the wood for over
an hour, it felt as if I had become a Hobbit.
Re-entering clear skies and sunshine was a welcome relief.
|

|
I walked back down the
field toward where the last bwlch survey had taken place and joined a track and
then path down through another wood, this led out onto the narrow lane at the
base of my first hill of the day; Allt y Clych, which shot up in tapered form.

|
The walk back on the
lane to my car was delightful as the early evening light gave a richness of
colour with far away hills being highlighted against a deep mass of succulent
grey cloud.
|
Succulent summer colour
|
These light conditions
only seem to happen in the summer months and give a rare intensity to summer
colour which is usually dulled and washed out.
I stood and happily took photos as sheep grazed in their fields and the
freshness of early summer growth gave an emerald colour to the trees.

|
Before leaving this
scene I looked back up toward the wooded slopes of Cefn Tŷ Mawr with the green
ridged top of Banc Craigol above, both are excellent hills as indeed is the
circuit I had now completed.

In all I took 22 data
sets and the walk had taken me 9 hr 35 min, which was quite a long time, but I
had been invited for afternoon tea on the way and spent an hour sitting in a
wood, happy times.
