Mapping Mountains – Summit Relocations – Y Trichant



Ffridd Top Llety (SJ 089 167)

There has been a Summit Relocation to a hill that is listed in the Y Trichant and which was initiated by LIDAR analysis, with the summit height, its position and the drop of the hill confirmed by a survey with the Trimble GeoXH 6000, which was conducted on the 5th April 2018.

The criteria for the list that this summit relocation affects are:

Y Trichant – All Welsh hills at and above 300m and below 400m in height that have 30m minimum drop, with an accompanying sub category entitled the Sub-Trichant consisting of all Welsh hills at and above 300m and below 400m in height that have 20m or more and below 30m of drop.  The list is authored by Myrddyn Phillips and the Introduction to the list and the re-naming and publication history was published on Mapping Mountains on the 13th May 2017. 

The name of the enclosed land where the summit of this hill is situated is Ffridd Top Llety and this was derived from local enquiry, and the hill is adjoined to the Y Berwyn range of hills which are situated in the south-eastern part of North Wales (Region A, Sub-Region A4), and is positioned between the B 4393 road to its north and the B 4382 road to its west, and has the small community of Llanfihangel-yng-Ngwynfa towards the west.

As the summit of the hill is not on designated open access land permission to visit should be sought, for those wishing to do so there are two public footpaths that cross the field where the summit is situated and which come within a few metres of its high point.

When this hill was originally listed in the Welsh P30 lists on Geoff Crowder’s v-g.me website it was by the name of Bryn and its 347m map heighted summit location given as SJ 085 169.  Since this hill was first listed the Ordnance Survey Interactive Coverage Map hosted on the Geograph website has become available online and this map shows a second 347m map heighted summit positioned at SJ 089 167. 


Gathering data at the summit of Ffridd Top Llety

These two summits and their respective connecting bylchau were analysed via LIDAR and surveyed with the Trimble GeoXH 6000.  The resulting summit data is given below:


Bryn

LIDAR:  346.239m at SJ 08501 16871

Trimble GeoXH 6000:  346.367m at SJ 08501 16870



Ffridd Top Llety

LIDAR:  346.619m at SJ 08997 16749

Trimble GeoXH 6000:  346.551m at SJ 08997 16748 


Therefore, the confirmation of the position of the relocated summit is at SJ 08997 16748 and this consists of closely cropped grass in an enclosed grazing field, this position is approximately 500 metres east south-eastward from where the previous prioritised 347m map heighted summit of Bryn is located.

Mapping Mountains – Significant Name Changes – Y Trichant


Fridd Top Llety (SJ 089 167)

There has been a Significant Name Change to a hill that is listed in the Y Trichant, with the summit height, summit location and drop of the hill being confirmed by a Trimble GeoXH survey which took place on the 5th April 2018.

The criteria for the list that this name change applies to are:

Y Trichant – All Welsh hills at and above 300m and below 400m in height that have 30m minimum drop, with an accompanying sub category entitled the Sub-Trichant consisting of all Welsh hills at and above 300m and below 400m in height that have 20m or more and below 30m of drop.  The list is authored by Myrddyn Phillips and the Introduction to the list and the re-naming and publication history was published on Mapping Mountains on the 13th May 2017.

The hill is adjoined to the Y Berwyn range of hills which are situated in the south-eastern part of North Wales (Region A, Sub-Region A4), and is positioned between the B 4393 road to its north and the B 4382 road to its west, and has the small community of Llanfihangel-yng-Ngwynfa towards the west.

Ffridd Top Llety (SJ 089 167)

The hill appeared in the 300m P30 list on Geoff Crowder’s v-g.me website under the name of Bryn, with its 347m map heighted summit positioned at SJ 085 168.  Since this hill was first listed the Ordnance Survey Interactive Coverage Map hosted on the Geograph website has become available and this map shows a second 347m map heighted summit positioned at SJ 089 167, these will be referred to as the westerly top and easterly top respectively in parts of this article.

As these two summits of this hill comprise bounded land the details for each were examined on the Tithe map.  The term Tithe map is generally given to a map of a Welsh or English parish or township and which was prepared after the 1836 Tithe Commutation Act.  This act allowed tithes to be paid in cash rather than goods.  The Tithe maps gave names of owners and occupiers of land in each parish and importantly for place-name research they also included the name of enclosed land.  This enclosed land is usually based on a field system, however not every field is given a name, but many are and especially so in Wales.

The enclosed land where the westerly top of this hill is situated is given the number 738 on the Tithe map, and the enclosed land where the easterly top of this hill is situated is given the number 663 on the Tithe map, these can be cross referenced against the apportionments; it is these apportionments that give the name of the owner or occupier of the land as well as the name of the land.  The land where the summit of the westerly top is situated is named as Cae Mawr, and the land where the summit of the easterly top is situated is named as Cefnydd, with the details on the Tithe map appearing in the county named as Montgomery and in the parish of Llanfihangel.

However, these names were those known for the enclosed fields at the time of the Tithe, and for listing purposes the names used should be those that the enclosed fields are nowadays known as, if indeed different to those from the time of the Tithe.  And the person to verify the present day name for each field is the local farmer whose land the westerly and easterly top of this hill is situated on, and the local farmer is Martin Davies.

When descending the hill I flagged Martin down who along with a colleague was driving a quad bike up the track to retrieve a dead lamb.  Martin is aged 54 and farms from Penisarllan, which is to the west of the hill and on the periphery of Llanfihangel-yng-Ngwynfa.  Martin explained that his Great Grandfather moved to Penisarllen as a tenant farmer in the 1930’s and that his father had bought the land from Sir Watkins Williams-Wynn in the 1950’s and 1960’s.  During our conversation Martin gave me a number of field names, including Cae Llan which was the field where we were standing and which at the time of the Tithe was known as Cae y Llan, however all other field names that Martin gave me were different to the time of the Tithe except for Cae Mawr, but this was the name given to a field a little north-east of his farm and not to the westerly top of the hill.

Martin Davies

The other field names that Martin gave were; Cae Llwybr which he said was a four acre square field, Ffridd Dan Fence which is not surprisingly the field under the fence and placed adjacent to the easterly top and Cae Chwarel which is the field adjacent to the old disused quarry.

I then asked Martin about the two higher fields, with the westerly one being above us from where we were standing, he said that this field is known as Bryn as it was adjoined to the old farmstead of Bryn which is situated to the south-east of the field, whilst the easterly one is known as Ffridd Top Llety as it was adjoined to the Llety farm, which is situated to the north-east of the field.

Therefore, as LIDAR analysis and Trimble data give the easterly field as higher than the westerly field the name this hill is now listed by in the Y Trichant is Ffridd Top Llety, and this was derived from local enquiry.

Mapping Mountains – Trimble Surveys – Y Berwyn


05.04.18  Bryn (SJ 085 168) and Ffridd Top Llety (SJ 089 167)

Ffridd Top Lletty (SJ 089 167)

I’m writing this as the rain teems down and the sky is a leaden grey, such a contrast to a few mornings ago when the sky radiated blue and spring warmth rejuvenated the land.

This walk was prompted by an email from Charlie Leventon who had recently visited this hill, and wondered about its high point and name.  These queries relate to the hill being given twin 347m map heighted tops, with one of these spot heights appearing on the Ordnance Survey Interactive Coverage Map hosted on the Geograph website. 

The hill is currently listed as Bryn both in the original Welsh 300m P30 list that appears on Geoff Crowder’s v-g.me website and also in the Tumps, with the latter data originating from the former.  However, although the word Bryn appears near this hill’s summit, map position indicates that it is more applicable to an old farmstead and not necessarily to the hill itself.

Prior to the walk I consulted the Tithe map as the land where these two tops are positioned is bounded, and at the time of the Tithe the land where the westerly top is situated was known as Cae Mawr and the land where the easterly top is situated was known as Cefnydd.  I had also analysed these tops via LIDAR and the easterly was shown as higher, if confirmed by the Trimble this would mean a relocation of the current prioritised summit.

With an 11.00am appointment in Welshpool and four surveys and hopefully place-name enquiries to make I needed an early start, and by 7.20am I was standing in a dew laden and slightly frosted field waiting for the Trimble to gather its allotted five minutes of data.  As the Trimble beeped away collecting its 300 datum points the sun edged its way over the hill ridge to my east and shone through branches still not budded.  This field and the point where the Trimble was positioned is the critical bwlch for the higher of the two tops and I had fun getting here as I drove up what I thought was the correct minor lane leading toward the bwlch, only to end up on a narrow concrete track with grass in the middle and ditches either side awash with water and mud that led to a closed gate and who knows what beyond, thankfully I extricated myself from what may have been a difficult situation for my car.

Once five minutes of data were stored I closed the Trimble down, packed it away and walked back to my car which was parked beside the drive / track entrance to Cefnllwyni, an old farm where I had parked a couple of years ago when surveying the hill to the west.

Next stop was the small car park in Llanfihangel-yng-Ngwynfa, it was 7.45am by the time I set off walking up the track leading to the westerly of the two tops and I wondered if I had sufficient time for all the surveys I wanted to conduct.

Llanfihangel-yng-Ngwynfa

New born lambs were shielded by proud mother’s as I made progress uphill, blue blazed overhead from a radiant sky and the motorised chugging of a tractor in a near farmyard was the only sound that interrupted an otherwise peaceful land.

Not very old and being shielded by its mother

I find a beauty in the simplicity of surveying, it affords time to stand and think, it also gives time for well-earned rests, and this morning as the Trimble gathered its data from the high point of the westerly top I stood and savoured the view with the high Aran and the Berwyn ridges floating above the greened and browned intervening land, nothing seemed to stir except for the distancing of the sound of the tractor and the movement of sheep and new born lambs.

Gathering data at the summit of Bryn

The enclosed field on the left is nowadays known as Bryn

It wasn’t far to the easterly top and I walked over the connecting bwlch between each on my way, this I would survey on my return.  The LIDAR grid reference for the summit led me to its high point and soon the Trimble was positioned atop my rucksack gathering data.

As data were gathered I headed down to the corner of the field to take photographs and soak in the scene were green met blue and all slumbered under an early morning that proved positively blissful.

The enclosed field on the right is nowadays known as Ffridd Top Llety

Once five minutes of data were gathered I closed the Trimble down and took more photos, the snow-capped and frosted ridge of the Berwyn to the north proved a welcome addition, adding perspective with height and distance to an otherwise greened landscape.

The high Berwyn

Just one survey remained and that was the connecting bwlch between these two tops, again the ten figure grid reference produced by LIDAR led me to the correct position and within a few minutes the Trimble was set-up gathering its customary five minutes of data.

Gthering data at the bwlch of Bryn

As I retraced my way back over the summit of the westerly top and then down its slopes I heard a quad bike whizzing around the near farmyard, I hoped it would not disappear down the road as I now wanted to make place-name enquiries with the local farmer.  Thankfully as I neared the gate giving access around the side of the village school to the car park, two quad bikes headed my way, I flagged for them to stop.

After explaining my interest in upland place-names, the farmer; Martin Davies kindly gave me ten minutes of his time as he and his colleague were heading up the track to retrieve a new born dead lamb.

Martin Davies

Martin gave me many field names which will be documented in a forthcoming post, with the two relating to the tops I had visited being; Bryn for the westerly summit and Ffridd Top Llety for the easterly summit.  Both names directly relate to buildings and both names are different to what these bounded fields were known as in the time of the Tithe, however one field name remained the same, this was the field where we were standing and Martin said its name is Cae Llan, and this when examined on the Tithe is recorded as Cae y Llan. 

Names change as indeed do known summit heights, but occasionally some remain the same.  Martin had now clarified the name of the bounded land where each summit is positioned and processing the data will probably confirm what LIDAR has already established as far as what summit is higher.
