Mapping Mountains – Significant Name Changes – 100m Twmpau and Y Trechol - The Dominant Hills of Wales


Coed Gaer (SH 799 808)

There has been a Significant Name Change to a hill that is listed in the 100m Twmpau and Y Trechol - The Dominant Hills of Wales; and the following details are in respect of a hill that was surveyed with the Trimble GeoXH 6000 on the 16th January 2016.

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

100m Twmpau - All Welsh hills at and above 100m and below 200m in height that have 30m minimum drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.

Y Trechol - The Dominant Hills of Wales - These are the Welsh P30 hills whose prominence equal or exceed half that of their absolute height.  

The hill is a part of the Rhos range, this group of hills includes Moelfre Uchaf and is an extension of Mynydd Hiraethog and is situated in the northern part of Wales.  The hill is positioned between the south-eastern outskirts of Llandudno to its north-west and Penrhyn Bay to its north-east.

The hill appeared in the 100m P30 list on Geoff Crowder’s v-g.me website under the partly invented name Pen Coed Gaer, with an accompanying note stating; Name from wood at summit.

    Two points of same height - other at SH799808. Name from wood at summit.
     
 
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 Pen, Bryn or Moel in front of them or as in this instance, use the name of the wood near to the summit of the hill and prefix it with the word Pen.  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.   

Extract from the Ordnance Survey 1:25,000 Explorer map

As an appropriate name for this hill already exists on Ordnance Survey 1:25,000 Explorer maps, the use of the invented and prefixed word of Pen is unnecessary, therefore the name this hill is now listed by in the 100m Twmpau and Y Trechol - The Dominant Hills of Wales is Coed Gaer.



The full details for the hill are:

Group:  Rhos

Mapping Mountains – Trimble Surveys – Long Mynd


24.09.16  Caer Caradoc Hill (SO 477 953, previously Trimbled), Willstone Hill (SO 485 943), Hope Bowdler Hill (SO 479 940) and Helmeth Hill (SO 469 938, only col Trimbled)   

Willstone Hill (SO 485 943)

The Shropshire hills offer so much, with their quiet beauty being a joy to re-visit.  The heartland of these hills is centred on the small market town of Church Stretton, and it here that Mark had suggested to meet; also joining us was Bob Kerr, who was driving north from Southampton and kindly taking me to Scotland afterward for Rick and Jen’s celebratory completion of the Marilyns.

Leaving two cars in the town I then drove northward to squeeze my car beside a gate on a track that gave us access to Caer Caradoc Hill, which is one of the gems of upland Shropshire.

This chosen route gave us access to the north ridge of the hill and as height was gained The Lawley stood proud with the flat plains beyond only reaching skyward again with the up thrust of The Wrekin, which proved an ever present distant pyramidal profile placed on the horizon.

Thankfully the forecast was for dry, albeit gusty conditions and as we crested the upper part of Caer Caradoc Hill the wind blasted across the landscape.  The customary summit photographs were taken with Bob adopting a celebratory pose as he ticked off another Marilyn.

At the summit of Caer Caradoc Hill

Dropping off the hill south-eastward gave us shelter and good paths led us down toward the col of Hope Bowdler Hill, which is listed as a Hump and Four, and which was our next main hill of the day.  I’d previously surveyed Caer Caradoc Hill with Charlie Leventon in March 2015, so decided to concentrate on summits and cols that had not yet been Trimbled.

Willstone Hill and Hope Bowdler Hill from the descent of Caer Caradoc Hill

Reaching the col I set the Trimble up placed on top of my rucksack to give it elevation above its immediate surrounds, quickly measured a 0.44m offset between its internal antenna and the ground at the base of the rucksack and once the 0.1m accuracy level was attained, pressed ‘Log’ and scampered off to join Mark and Bob who were happily munching on their lunch.

Gathering data at the col of Hope Bowdler Hill

Above us were the gently sloped upper reaches of Hope Bowdler Hill and its lower neighbour; Willstone Hill, which is listed as a Sub-Four with the minimum qualifying drop of c 20m.  It seemed a shame to miss out on giving this hill an accurate height and drop and so after the col data was gathered we headed its way.

Willstone Hill is crowned by rounded heathland with a volcanic plug at its far north end, the high point of which clearly vied for being the summit of the hill.  Bob skipped up it and conducted a quick precision survey comparing its height against that of the heathland at its base, it was decided to Trimble both, and as Mark and Bob waited patiently I positioned the Trimble aligned with the high point of the rock outcrop and as the strength of the wind was somewhat strong I attached its dog lead which I held as the five minutes of data were gathered.

Afterward I set the Trimble up on my rucksack at the high point of the land near the base of the rock outcrop and as the five minutes of data were collected Mark and Bob headed down to the adjoining col seeking shelter out of the wind.

Gathering data at the lower heath land summit of Willstone Hill

Once data were gathered I joined them and we all set about pinpointing the critical col of Willstrone Hill, this proved to be ground beside a fence which thankfully was well sheltered from the strong wind.  Once the customary five minutes of data were gathered I packed the Trimble away and we walked up the good path to the summit of Hope Bowdler Hill.

Gathering data at the col of Willstone Hill

The high point of Hope Bowdler Hill is about 14 metres from its small summit cairn amongst heathland scrub of wind-blown grass.  Having been away from Trimbling hills for two months it was good to be out again, and especially so in the company of Mark and Bob, both of whom I hadn’t seen for quite a time. 

Gathering data at the summit of Hope Bowdler Hill

After summit data were stored we retraced our inward route back toward the hill’s col and continued on another good path, this time amongst bracken toward the col of Helmeth Hill which was our last hill of the day.

The col was positioned in a field and was Trimbled, however the summit is positioned in an attractive deciduous wood and although I set the Trimble up at the high point it did not achieve its accuracy level before data should be logged, and having waited five minutes for it to do so, we decided that I should switch the equipment off and it was time to head down.

Gathering data at the col of Helmeth Hill

Our route toward Church Stretton took us steeply down through the wood and on to paths and tracks leading us to the periphery of the town.  Mark later checked the distance and ascent for the day’s walk and with approximately 600m of ascent it had proved a good day out, it was also good to see both Mark and Bob again, hopefully we’ll be on the hill again shortly.

Mapping Mountains – Significant Name Changes – 100m Twmpau and Y Trechol - The Dominant Hills of Wales


Trwyn y Fuwch (SH 813 823)

There has been a Significant Name Change to a hill that is listed in the 100m Twmpau and Y Trechol - The Dominant Hills of Wales; and the following details are in respect of a hill that was surveyed with the Trimble GeoXH 6000 on the 16th January 2016.

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

100m Twmpau - All Welsh hills at and above 100m and below 200m in height that have 30m minimum drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.

Y Trechol - The Dominant Hills of Wales - These are the Welsh P30 hills whose prominence  equal or exceed half that of their absolute height.  

The hill is a part of the Rhos range, this group of hills includes Moelfre Uchaf and is an extension of Mynydd Hiraethog and is situated in the northern part of Wales.  The hill is positioned overlooking the north Wales coastline and Ormes Bay which is also known as Llandudno Bay, and has the communities of Craigside to its west south-west and Penrhyn Bay to its south-east.

The Trimble  GeoXH 6000 gathering data on the summit of Trwyn y Fuwch

The hill appeared in the 100m P30 list on Geoff Crowder’s v-g.me website under the name of Creigiau Rhiwledyn, which is a name that appeared close to the summit of the hill on Ordnance Survey maps of the day.  


Creigiau Rhiwledyn
    141m
    SH813824
    116

    aka Little Orme or Little Ormes Head. Clem/Yeaman. Trig pillar.
     

During my early hill listing I paid little regard to name placement on a map, or the meaning of names and to what feature the name was appropriately applied to.  Therefore I prioritised names for listing purposes that I now understand are inappropriate, and Creigiau Rhiwledyn is such an example as this name has been consistently applied by the Ordnance Survey to the cliffs that are positioned north-eastward of this hill’s summit, and although it can be appropriate to use the main named feature of a hill when naming it for listing purposes, in this instance the hill has its own name, and this is Trwyn y Fuwch.  In addition to its Welsh name the hill is also known by its English name of Little Orme.

Therefore the name this hill is now listed by in the 100m Twmpau and Y Trechol - The Dominant Hills of Wales is Trwyn y Fuwch, and this was derived from a number of sources including the Dictionary of the Place-Names of Wales (Hywel Wyn Owen and Richard Morgan, Gomer Press 2007).  



The full details for the hill are:

Jenny Hatfield and Rick Salter complete the Marilyns


Congratulations to Jenny and Rick who on the 25th September 2016 completed the Marilyns on Cruinn a’Bheinn (NN 365 051) above Loch Lomond in Scotland.  In doing so Jenny became the 1st female to complete the Marilyns and Rick the 9th male.

Rick and Jen complete the Marilyns on Cruinn a'Bheinn

They were joined by a number of friends for the summit celebrations and copious amounts of Champagne, whiskey and cake kept the throng happy as blustery showers blew in from the west.


There are currently 1,556 Marilyns in Britain and the listing forms one of the toughest challenges for any hill bagger.  The celebratory chant was led by list author; Alan Dawson, who compiled the listing of Marilyns which was first published by Cicerone Press in 1992 in The Relative Hills of Britain book.

A Marilyn is a hill of any height that has a minimum 150m of drop.

Rick and Jen’s Marilyn completion has been covered by numerous online websites, including:

Mapping Mountains – Significant Name Changes – 100m Twmpau


The Pimple (SJ 299 472)

There has been a Significant Name Change to a hill that is listed in the 100m Twmpau, and the following details are in respect of a hill that was surveyed with the Trimble GeoXH 6000 on the 20th October 2015.

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

100m Twmpau - All Welsh hills at and above 100m and below 200m in height that have 30m minimum drop, with an accompanying sub category entitled the 100m Sub-Twmpau taking in all Welsh hills at and above 100m and below 200m in height that have 20m and more and below 30m of drop, with the word Twmpau being an acronym standing for thirty welsh metre prominences and upward.

The hill is a part of the Moel y Gamelin range; this group of hills are situated in the north-eastern part of north Wales.  The hill is positioned above the B 5426 and B 5605 roads and is situated on the northern outskirts of Rhosllanerchrugog.

The Trimble GeoXH 6000 gathering data at the summit of The Pimple

Prior to the survey with the Trimble GeoXH 6000 the hill was not classified as it had not appeared in any known listing of hills.  Therefore, although there is no change in this hill’s listed name it is worth categorising under the heading of Significant Name Changes as the name this hill is now listed by comes from local enquiry, with the hill's height and classification being confirmed by the survey with the Trimble GeoXH 6000.   
    
Extract from the current Ordnance Survey 1:50,000 Landranger map

Extract from the Ordnance Survey 1:25,000 Explorer map

Therefore, the name this hill is now listed by in the 100m Twmpau is The Pimple, and this is a locally known name for the summit of the hill and is known as such by the family who live in the house directly below the hill to the west, beside the area of the hill’s bwlch.  The house used to be the office of the old mine that operated on a part of the hill, with the family of the current residents having lived here for five generations and with the name of The Pimple having been used for many years. 


The full details for the hill are:

Group:  Moel y Gamelin

Name:  The Pimple
