Mapping Mountains – Significant Name Changes – 30-99m Twmpau


Cae Canol (SH 498 709) 

There has been a Significant Name Change to a hill that is listed in the 30-99m Twmpau, with the summit height, bwlch height and their locations, the drop and status of the hill derived from LIDAR analysis conducted by Myrddyn Phillips.

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

30-99m Twmpau – Welsh hills at or above 30m and below 100m in height that have 30m minimum drop, with an accompanying sub list entitled the 30-99m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 30m and below 100m in height with 20m or more and below 30m of drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.

The hill is adjoined to the Ynys Môn group of hills, which are situated in the north-western part of North Wales (Region A, Sub-Region A1), and it is positioned with a minor road next to its summit and the A5 and A55 roads to its north, and has the village of Llanddaniel-fab towards the south-west. 

When the original 30-99m height band of Welsh P30 hills were published on Geoff Crowder’s v-g.me website this hill was not included in the Hills to be surveyed sub list, as it was considered not to meet the criteria then used for this sub category. 

After the sub list was standardised, and interpolated heights and drop values also included the details for this hill were re-evaluated and it was listed under the point (Pt. 66m) notation with an estimated c 25m of drop based on the 66m summit spot height and an estimated c 41m bwlch height based on interpolation of 5m contouring between 40m – 45m that appear on the Ordnance Survey 1:25,000 Explorer map.

As the summit of this hill comprises bounded land the details for it 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. 

Extract from the Tithe map

The enclosed land where the summit of this hill is situated is given the number 411 on the Tithe map, this 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 this hill is situated is named as Cae Canol in the apportionments, with the details on the Tithe map appearing in the parish of Llanddaniel and in the county named as Anglesey. 

Extract from the apportionments

Therefore, the name this hill is now listed by in the 30-99m Twmpau is Cae Canol and this name was derived from the Tithe map.

Group:  Ynys Môn 

Name:  Cae Canol

Mapping Mountains – Hill Reclassifications – 30-99m Twmpau


Cae Canol (SH 498 709) – 30-99m Sub-Twmpau addition

There has been confirmation of an addition to the list of 30-99m Twmpau, with the summit height, bwlch height and their locations, the drop and status of the hill derived from LIDAR analysis conducted by Myrddyn Phillips.

The criteria for the list that this addition applies to are: 

30-99m Twmpau – Welsh hills at or above 30m and below 100m in height that have 30m minimum drop, with an accompanying sub list entitled the 30-99m Sub-Twmpau with the criteria for this sub category being all Welsh hills at or above 30m and below 100m in height with 20m or more and below 30m of drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.

The name the hill is listed by is Cae Canol and this was derived from the Tithe map, and it is adjoined to the Ynys Môn group of hills, which are situated in the north-western part of North Wales (Region A, Sub-Region A1), and it is positioned with a minor road next to its summit and the A5 and A55 roads to its north, and has the village of Llanddaniel-fab towards the south-west. 

When the original 30-99m height band of Welsh P30 hills were published on Geoff Crowder’s v-g.me website this hill was not included in the Hills to be surveyed sub list, as it was considered not to meet the criteria then used for this sub category.

However, it was not until LIDAR became available that the details for this hill could be accurately re-assessed.  The LIDAR (Light Detection & Ranging) technique produced highly accurate height data that is now freely available for much of England and Wales. 

Therefore, the confirmation of the addition of this hill to 30-99m Sub-Twmpau status is due to LIDAR analysis, resulting in a 65.5m summit height and a 40.45m bwlch height, with these values giving this hill 25.1m of drop, which is sufficient for it to be classified as a 30-99m Sub-Twmpau.

Mapping Mountains – Significant Name Changes – Y Trichant - The 300m Hills of Wales


Cae Canol (SJ 098 172)

There has been a Significant Name Change to a hill that is listed in the Y Trichantwith the height and drop of the hill derived from a Trimble GeoXH 6000 survey which took place on the 4th May 2016 and subsequent LIDAR analysis.

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

Y Trichant These are the Welsh hills at and above 300m and below 400m in height that have 30m minimum drop,  with the introduction to the re-naming and publication history of this list appearing on Mapping Mountains on the 13th May 2017.

The hill is a part of the Y Berwyn range, this is an extensive group of hills in the south-eastern part of north Wales, and the hill is positioned to the south of the B 4393 road and between the town of Llanfyllin to its east north-east and the small community of Llanfihangel-yng-Ngwynfa to its west south-west. 

The Trimble GeoXH 6000 gathering data at the summit of Cae Canol

The hill appeared in the 300m P30 list on Geoff Crowder’s v-g.me website under the partly invented name Bryn Cefnllwyni, with an accompanying note stating; Name from buildings to the North-East.  During my early hill listing I thought it appropriate to either invent a name for a hill, or use a name that appeared near to the summit of the hill on Ordnance Survey maps of the day.  My preference was to use farm names and put PenBryn or Moel in front of them and in this instance, use the name of a near house and prefix it with the word Bryn.  This is not a practice that I now advocate as with research either conducted locally or historically an appropriate name for the hill can usually be found.

    Name from buildings to the North-East


The name this hill is now listed by is Cae Canol, and the land that this name is applicable to was confirmed via 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.

Accessing information on the Tithe map is simplified by the use of a split screen enabling the summit to be pinpointed on the map on the right and for the same point to appear on the Tithe map on the left

The land where the summit of this hill is situated is named as Cae Canol on the Tithe map

The enclosed land where the summit of this hill is situated is given the number 141 on the Tithe map, this 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 this hill is situated is named as Cae Canol on the Tithe map; it appears in the county named as Montgomery and in the parish of Llanfihangel-yng-Ngwynfa.


The full details for the hill are:

Group:  Y Berwyn

Name:  Cae Canol

Previously Listed Name:  Bryn Cefnllwyni 

Summit Height:  323.2m (converted to OSGM15)

Mapping Mountains – Trimble Surveys – Y Berwyn


04.05.16  Cae Canol (SJ 098 172) 

Cae Canol (SJ 098 172)

Having previously visited Craig Garth Bwlch (SJ 018 181) and Moel y Gôd (SJ 072 168) I wanted a leisurely stroll to the top of another small hill to round off the day’s activities.  Over the years I’d visited a number of P30s between Llanfyllin and Llanwddyn but a 323m map heighted hill at SJ 098 172 had escaped my attention.

I parked relatively high on a minor lane beside the entrance to Cefnllwyni, a rather grand and well-kept house that now offers Bed and Breakfast.  A public footpath makes its way westward from this point toward Llanfihangel-yng-Ngwynfa, I chose the left track of two and hoped that this was the path.  As the track rounded the back of Cefnllwyni I had my doubts and this was soon confirmed by the owner of the house.  We chatted for ten minutes or so, he’d lived there for twenty years having moved from Cheshire, I asked about the name of his house and whether he’d ever heard the hill being called the same name, he said he hadn’t and that he’d never heard a name for the hill.  I explained what I hoped to do, and he kindly directed me over a fence, through a gate in to a field and toward the top of the hill.  I later checked the Tithe map and the field where the summit of this hill is situated is named Cae Canol, and this is now being used for its listed name.

Once in the field the land opened up with extensive views in all directions, but it was the high Aran that my gaze concentrated on, these are wonderful mountains and form a block of rock set against rolling hills when seen from this vantage point.

On my way to the summit I passed a number of sheep lolled asleep in the afternoon sunshine, seemingly oblivious to my presence as my camera’s shutter clicked and I quietly moved on trying not to disturb their slumber.

Enjoying the day

I took data from three separate points with two vying for the hill’s high point.  During this time my mind wandered and examined one or two perplexing and interesting things currently on the go in my life, it seems doing this in the environment of a hill walk is ideal as it affords a certain uncluttering of periphery detail where one’s mind can concentrate on the subject at hand.  This thought process is more evident when surveying as extended time spent in one place usually takes place, during this time one can stand motionless in thought which can be a wonderful, fulfilling and constructive process.

Gathering data at the summit of Cae Canol

Having gathered summit data I followed the hill’s north-westerly summit fence toward where it intersects with the public footpath and followed this westward toward the area of this hill’s bwlch.  I found this to be in a field where a lively horse was resident.  I tried to go about my business in a quiet and non-confrontational way and a few minutes later had gathered another two data sets, all in view of the horse and a house from where voices emanated.

Gathering data at the bwlch of Cae Canol

Once happy that my day’s data gathering had been completed I packed the Trimble away and followed the footpath back over the hill and down toward Cefnllwyni, stopping for another chat with the owner who was out gardening next to his manicured lawn.
