On Location with S4C

 

On Location with S4C

Introduction:

In June 2014 Mapping Mountains published an article as a part of the Guest Contributor heading on the site, written by Aled Williams and entitled The Islands of Traeth Mawr. 

Traeth Mawr is the land immediately east of the Cob adjacent to Porthmadog in north-west Wales.  The Cob is an embankment which nowadays has a road and rail track running across it.  It was built as a sea defence resulting in the drainage of land for agriculture.  Prior to it being built the sea at high tide would have pushed inland. 

The Traeth Mawr area has many rocky small heighted hills, which when the sea pushed inland prior to the building of the Cob would have formed islands, these islands are now landlocked.  Many are wooded and rough underfoot, but all are well worth investigating. 

Over recent years Aled and I have done just that; visiting and surveying many of these landlocked islands and in the process building up a greater understanding of this area.  Aled’s article concentrated on the history of the Cob and these landlocked islands. 

 


S4C and the Cynefin programme: 

S4C is the Welsh language TV channel and the Cynefin programme is a documentary series that visits different places throughout Wales; with each programme concentrating on one area, highlighting local and unusual stories. 

For one of the programmes in the upcoming series they wanted to concentrate on Porthmadog.  During their research they came across Aled’s article published on Mapping Mountains.  More research unearthed the various surveys we had conducted on the landlocked islands of Traeth Mawr. 

In August of last year I received an email from Llŷr Titus; a researcher working on Cynefin.  They wanted to contact Aled having found his article on Mapping Mountains.  I forwarded this to Aled and he then contacted Llŷr. 

As with many outdoor broadcasts time restraint and weather can dictate schedules and it was not until December of last year that Aled’s continued discussion with the researchers and producer of Cynefin finally set a date to meet.  In the interim I was invited to attend as they wanted the Trimble as a part of the programme, with this being the survey equipment that had put an accurate height and position to many of the summits of these landlocked islands. 

 


Deciding which Island: 

There were a number of possibilities of what island to visit and film from.  However, there was the prospect of large cameras in tow and a number of people making up the Cynefin crew to consider.  As many of these islands are rough underfoot comprising bramble, rock and gorse it was suggested that Ynys Tywyn would be ideal.  This island can be easily accessed from the centre of Porthmadog, with its path leading to a relatively open summit area that gives dramatic and extensive views.

Meeting in Porthmadog: 

My role in proceedings was secondary, but as owner of the Trimble I needed to be present.  The date given for filming was Saturday 10th December with an 8.00am meeting time.  Aled suggested being at his home for 7.30am, this meant leaving Welshpool no later than 6.00am, however the forecast was not ideal as snow had recently fallen and iced road conditions were forecast for the west of Wales, therefore I set off at 5.30am.  The journey to Porthmadog was beautiful as moonlight bathed all surrounds, but the journey was also rather exciting as a good dusting of snow lay on the road heading toward Dinas Mawddwy, with lots of snow falling as I continued on my way over the high road past Trawsfynydd.  I arrived at Aled’s at 7.10am and sat in the car waiting for a heavy hail and sleet shower to subside! 

After a paned we drove in to town and met Lleucu Gruffydd; the producer and Heledd Cynwal; the presenter before heading in to the warmth of a near café for a drink and conversation.  It is always good meeting people from the medium of television, the majority put you at ease instantly and it was no different with Lleucu and Heledd.  We were soon joined by Aled Davies-Jones; the director, editor and cameraman and Rhys Thomas; the cameraman.  Next stop Ynys Tywyn.

Visiting Ynys Tywyn: 

From where we met it was only a short walk over the road to the start of the path that ascents Ynys Tywyn.  As we set off a flurry of rain swept across the land, thankfully this quickly disappeared leaving our time on the summit dry, albeit increasing chilly. 

We stayed on top for almost two hours as Aled was interviewed about the history of the Cob and the islands of Traeth Mawr, this was done with the backdrop of snow-capped peaks occasionally making an appearance through grey winter cloud. 

Away in the distance showers pushed in from the coast, these in the main headed south toward the Rhinogydd, but they were always dramatic with beautiful blue hued winter colour set against the whitened grey of distant sky, with the ever present becalmed sea as foreground.  It certainly was a perfect place to meet and film.

During filming I stayed in the background and enjoyed watching everyone busy at work.  As a part of the film they wanted to know the processes at work to achieve an accurate result for the height and position of the islands we had surveyed.  Therefore, Aled had brought an Abney level and was filmed explaining its purpose and how to use it.  Afterwards it was time for the Trimble to make its entrance.

After explaining the fineries behind how the Trimble operates, Aled placed it aligned with the highest part of the slanting rock that makes up the summit of Ynys Tywyn and was filmed doing so.  The survey result could then be given to camera as well as further explanation of the processes at work.

After almost two hours on the summit area it was time to leave and head down.  The Cynefin film crew and Aled still had two other places to visit and the filming went on for the remainder of the day, whilst I needed to head back home before the roads froze and darkness fell. 

It had been a very enjoyable experience meeting the film crew from Cynefin and although no date is yet set for when the programme will appear on S4C I look forward to when it does.

Mapping Mountains – Trimble Surveys – Moel Hebog


10.12.22  Ynys Tywyn (SH 571 385) 

Ynys Tywyn (SH 571 385)

Ynys Tywyn is easily accessed from the centre of Porthmadog, it is one of those small hills that pays dividends, with little ascent being rewarded with extensive views.  I had visited once before in December 2014 when along with Aled we decided upon an easy hill as the forecast winter rain was bearing down on us.  On that occasion its summit was Trimbled.

That ascent was part of many that Aled had organised as we continued our investigation of Traeth Mawr; the flatlands to the immediate east of the Cob.  The Cob is the embankment built on the outskirts of Porthmadog to keep the sea from heading inland at high tide.  When it did so, the islands of Traeth Mawr must have been a wonderful sight, poking their wooded summits above the sea.  These now landlocked islands can still be accessed, although many are rough underfoot, but they are also rewarding to investigate.

Today we were in the company of a film crew from the Cynefin programme which is broadcast on S4C.  They were concentrating on the area surrounding Porthmadog and in particular the Cob.  They had approached Aled to be a part of this programme having found his article on Traeth Mawr published on Mapping Mountains, suggesting that a visit to one of these islands with the Trimble in tow would be good to film.

I drove to Aled’s and arrived at 7.10am having experienced slow progress on much of the route due to a dusting of snow on the road.  The journey was particularly beautiful as moonlight highlighted silhouetted hills that shone back under their covering of snow.

We met Lleucu and Heledd; the producer and presenter in the centre of Porthmadog before having an early morning paned.  Afterwards we were joined by Aled and Rhys; the director/cameraman and cameraman respectively.  By now a mixture of winter rain and occasion hail was descending from above.

The walk to the top of Ynys Tywyn is only short, following a path through its wooded slopes to the impressive slanting rock that constitutes its summit.  The upper part of the hill had a sprinkling of frost on it adding winter colour to the scene.

It is not my intention to go in to any great detail of the filming in this article as a future On Location with S4C post will document this.  We stayed on top for almost two hours with Aled being filmed explaining the process behind using an Abney level and the Trimble.

During this I happily listened to the proceedings from the background enjoying being out on this small island, which nowadays is connected to the town of Porthmadog by the Cob.  I spent much of the time watching the play of light as winter showers pushed inland from the coast.

In the distance snow-capped peaks occasionally emerged from their winter shroud, with the upper part of Cnicht springing out of the grey misted scene with its pyramidal summit profile looking ever impressive.  However, many hills were obscured with deep grey cloud penetrating their depths. 

Snow-capped hills

For a relatively small hill Ynys Tywyn certainly has a dramatic and expansive view.  The workings of the film crew would occasionally be interrupted by the hoot emanating from the steam train as it chugged its way across the Cob, bellowing smoke across the harbour surrounds.

The last shots were of Aled explaining the fineries of the Trimble and then it was time to head down.  For Aled the filming would go on for the rest of the day, but for me it was time to head home before the roads froze and darkness fell.

Mapping Mountains – Hill Reclassifications – 30m–99m Twmpau


Ynys Tywyn (SH 571 385) - Double Sub-Twmpau addition   

There has been an addition to the 30-99m Twmpau list with this hill entering the caregory of Double Sub-Twmpau.  The name of the hill is Ynys Tywyn (SH 571 385) and it is situated at the end of the Cob in Porthmadog in north-west Wales.  

Ynys Tywyn has a small uppermost 20m contour ring on Ordnance Survey maps, but no spot height, and a recent survey with the Trimble GeoXH 6000 confirms that the hill is over 20m but under 30m in height and as it is the high point of an island that is now connected to Porthmadog by the Cob, and therefore its height is also considered to be its drop, it has been included in the Double Sub-Twmpau category.  The summit is crowned by a large flat rock and gorse bushes and has fine views over the Afon Glaslyn to the higher mountains of Eryri.


The full details for the hill are:

Cardinal Hill:  Moel Hebog

Summit Height:  21.8m (converted to OSGM15)

Name:  Ynys Tywyn

OS 1:50,000 map:  124

Summit Grid Reference:  SH 571 385

Drop:  21.8m (converted to OSGM15)


Ynys Tywyn (SH 571 385) is now confirmed as a Double SubTwmpau

Mapping Mountains – Trimble Surveys – Moel Hebog



31.12.14  Ynys Tywyn (SH 571 385)   

Ynys Tywyn (SH 571 385)

After a week at my brother’s in Nantlle it was time to head home, but not until I met Aled in Porthmadog to catch up with all things hilly, place-namey and hill-listy.  We sat in my car nattering away until he persuaded me to visit Ynys Tywyn which would take no more than half an hour up and down including surveying its highest point.

As I’m easily persuaded I quickly got my wellies on, grabbed my camera, Trimble and rucksack and drove to the end of the Cob and found a parking place overlooking the harbour.

Ynys Tywyn is as its name implies; an island, it is now joined to Porthmadog by the Cob which extends in a north-westerly to south-easterly direction across the mud and sand of the Afon Glaslyn estuary.  When travelling into Porthmadog this small island is easily missed as a large cream coloured house obstructs all but the highest trees growing on the island.

Plaque on wall at the start of the path

As we made our way from the car to the path that climbs up to the high point the weather closed in and the first few wind-blown rain drops fell.  The weather forecast was not good, but we hoped that the downpour would relent until we had visited the summit and arrived safely and dry back at the car.

Leaving the road and arriving on the earthen path was like being transported to another world where the busy bustle of the town was instantly left and an overgrown pleasant island land found.

Heading toward the summit of Ynys Tywyn

The path led to a rocky summit with two positions vying for the accolade of the highest point, one was on a large rock with a big vertical drop on one side, whilst the other was in the middle of a strangly looking gorse bush.

We decided to survey the rock summit first and attached the Trimble to my rucksack and placed the latter on the safe side of the summit.  By doing so the Trimble could be aligned with this high point but would not be blown over the vertical drop as it was attached to a weighty rucksack.  However, when this contraption was first set in place the wind blew the rucksack down the rock, so once positioned again in place, Aled lay on the rock with his head cushioned on the rucksack to keep it firmly in place.  I wonder if OS field surveyors ever have to do things like this.

Gathering data from the first of two high points on Ynys Tywyn

As the last of the 300 datum points were collected I grabbed the Trimble and rucksack and moved over toward the gorse bush, Aled found a stable position for the Trimble and I placed my rucksack down slope from it just in case it decided to take a roll, again safeguarding it from an early death over a cliff.

Gathering data from the second of two high points on Ynys Tywyn

Thankfully the rain that had started had now stopped and once the Trimble was packed away we headed down to gain a view of the cliff from below it on its eastern side.
 
Aled then showed me the sluice gate which the Afon Glaslyn is fed through, from this vantage point the island overlooked the river with its lower section protected by gorse and sapling trees.

Across the other side of the sluice gate was the continuation of the footpath and another small island; Ynys Cerrigduon, which looked like another small compact island, this time with a trig pillar at its summit.  This little beastie could wait for another day. 

Happy that summit data had been collected from Ynys Tywyn we headed back to the car for an hour or so of hill chat before Aled headed out with his friends to Beddgelert to bring in the New Year.
