Ynys Hir (SH 566 396) - Dominant addition

There has been an addition to the listing of Y Trechol – The Dominant Hills of Wales due to a survey with the Trimble GeoXH 6000.  This has resulted in the hill being added to the Dominant list.  With the criteria for inclusion to this list being those Welsh P30 hills whose prominence equal or exceed half that of their absolute height.

The details relating to this hill’s inclusion as a Dominant hill are retrospective as it was surveyed on the 1^st February 2014 and later appeared in the Moel Hebog group of Dominant hills when published on the Mappingn Mountains site on the 28^th January 2016.

Prior to the survey with the Trimble this hill was unclassified as the Ordnance Survey 1:50,000 Landranger map, 1:25,000 Explorer map and the enlarged mapping hosted on the Geograph website all give the hill an uppermost 20m ring contour, implying that its height is not sufficient for P30 status and consideration as a Dominant hill.  However, it was Aled Williams who first proposed that this hill may attain P30 status and it was subsequently surveyed in his company.

The hill is in the Moel Hebog group of hills and is placed in the Region of North Wales (Region A, Sub-Region A1) and is situated between the communities of Porthmadog to its south and Tremadog to its north north-west, with the A 487 road to its immediate south.  The hill can be visited from this road where a lay-by gives access through a gate into the woodland that covers this and the other adjacent small hills.

The name of the hill is Ynys Hir and as its name implies it forms an island, which is now landlocked, it is included as a Dominant hill as the survey with the Trimble GeoXH 6000 produced a summit height of 37.3m, and with an estimated bwlch height of c 3m it gives this hill 91.21% Dominance.

The full details for the hill are:

Group:  Moel Hebog

Name:  Ynys Hir

Dominance:  91.21%

OS 1:50,000 map:  124

Dinas Dinlle (SH 436 564) - Dominant addition

There has been an addition to the listing of Y Trechol – The Dominant Hills of Wales due to detail included on the Ordnance Survey enlarged mapping hosted on the Geograph website and which was first spotted by Chris Watson, and subsequently confirmed via a survey with the Trimble GeoXH 6000.  This has resulted in the hill being added to the Dominant list.  With the criteria for inclusion to this list being those Welsh P30 hills whose prominence equal or exceed half that of their absolute height.

The details relating to this hill’s inclusion as a Dominant hill are retrospective as it was added to the list shortly after its initial compilation and later appeared in the Moel Hebog group of hills when published on Mapping Mountains on the 28^th January 2016.

Prior to Chris Watson raising the probability of this hill being a P30 and its subsequent inclusion as a Dominant hill it had remained unclassified, as the Ordnance Survey 1:50,000 Landranger map gave a 31m summit spot height and bwlch contouring between 0m – 10m, whilst the 1:25,000 Explorer map gave an uppermost 30m ring contour and the same bwlch contouring, which implied that the hill did not have the required 30m of drop to be considered for Dominant status.

The hill is positioned in the Moel Hebog group of hills and is placed in the Region of North Wales (Region A, Sub-Region A1) and is situated on the outskirts of the small community that takes its name from the hill; Dinas Dinlle, and is positioned with the sea to its immediate west which has eroded much of its slopes over recent years.  If wanting to visit the hill it can be easily accessed from the car park adjacent to the sea front from where a path heads up its northern slopes.

The name of the hill is Dinas Dinlle and as its name implies the upper section of the hill comprises an ancient hill fort, it was included as a 30-99m Twmpau as the Ordnance Survey enlarged mapping hosted on the Geograph website has contours at 5m intervals giving the hill an uppermost contour of 35m and bwlch contouring between 0m – 5m, these values give the hill an estimated drop of c 31m – c 32m.  The summit of this hill has subsequently been surveyed with the Trimble GeoXH 6000 as 34.7m (converted to OSGM15) and with a 4.1m bwlch height ascertained from LIDAR analyis, these values give this hill 30.6m of drop and 88.22% dominance. 

The full details for the hill are:

Group:  Moel Hebog

Name:  Dinas Dinlle

Dominance:  88.22%

Change Register

The 500-Metre Tops of Ireland

490m Double Subs

The 500-Metre Tops of Ireland are the Irish hills at or above 500m and below 609.6m (2,000ft) in height that have a minimum drop of 30m.  The list is co-authored by Michael Dewey and Myrddyn Phillips with each having produced a version of the list independent of the other.  Michael’s list originated in 1998 and comprised 186 hills, whilst Myrddyn’s list originated in 2000 and comprised 191 hills with a further 29 hills listed in a sub list entitled ‘Hills that need on the spot surveying with the prospect of being future additions’, this sub list forms the basis of the 500m Subs that now accompanies the main P30 list.

The list produced by Myrddyn was sent to a number of people including Michael Dewey and the Mountaineering Council of Ireland (now named Mountaineering Ireland).  Having produced versions of the same list the two authors combined each and decided to produce one co-authored list.  Data were re-evaluated and the updated co-authored list was sent to the Mountaineering Council of Ireland and later formed the lower height band of the list that appeared on the fledging MountainViews website in 2002, this list was later named the Arderins in 2009, with the higher height band of this list using data from the late Joss Lynam’s 600m Irish list.   

The 500-Metre Tops of Ireland listing was next fully re-evaluated with assistance from Jim Bloomer prior to it being published on the Hill Bagging website on 1^st June 2011, and it was then published in the downloadable Access and Excel versions (v12.0) of the Database of British and Irish Hills (DoBIH) on 27^th November 2011.  During this process the original sub list was also fully re-evaluated and appeared in the Hill Bagging publication entitled subMyrddynDewey, this sub list is referred to as the 500m Subs in the Change Registers published on Mapping Mountains.

However, it wasn’t until the Hill Bagging publication and the subsequent Database of British and Irish Hills (DoBIH) publication that the listing included two other sub categories; the 490m Subs and the 490m Double Subs and this Change Register details those hills that are, or have been listed within the 490m Double Subs category.  These two sub categories are not officially tied to The 500-Metre Tops of Ireland list on either the Hill Bagging or the DoBIH publication, but these data were sourced from The 400-Metre Tops of Ireland list compiled by Myrddyn Phillips and subsequently duplicated by MountainViews and renamed The Carns.  As these data are officially a part of The 500-Metre Tops of Ireland list, the hills incorporated are documented in this Change Register.  The 490m Double Subs comprise all Irish hills that fail to meet the The 500-Metre Tops of Ireland qualification by less than 10m of height and also less than 10m of drop, these are the hills that are 490m or more and below 500m in height that have 20m or more and below 30m of drop, they are known as the 490m Double Subs.

Although the criteria has remained the same The 500-Metre Tops of Ireland list has changed greatly since its first publication with the advent of independent surveyors enabling greater accuracy for numerical data, and the meticulous research conducted by Paul Tempan and incorporated by MountainViews, the listing also now incorporates three Sub categories, the 500m Subs, the 490m Subs and the 490m Double Subs which this Change Register details.

It seems fitting that the list of The 500-Metre Tops of Ireland – 490m Double Subs should now benefit from a detailed Change Register, and although the compilation to this sub list took place when the data were re-evaluated prior to publication on the Hill Bagging website in 2011, it is prudent for this Change Register to initially detail the changes to the list since this publication.

Mapping Mountains – Hill Reclassifications – Y Trechol – The Dominant Hills of Wales

Geirth Mawr (SH 535 393) - Dominant deletion

There has been confirmation of a deletion from the list of the Y Trechol – The Dominant Hills of Wales, with the summit height, bwlch height and their locations, the drop, dominance and status of the hill derived from detail on contemporary maps produced from Ordnance Survey data and confirmed from subsequent LIDAR analysis conducted by Myrddyn Phillips. 

LIDAR image of Geirth Mawr (SH 535 393)

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

Y Trechol - The Dominant Hills of Wales - Welsh P30 hills whose prominence  equal or exceed half that of their absolute height.  With the criteria for Lesser Dominant status being those additional Welsh P30 hills whose prominence is between one third and half that of their absolute height.  The list is authored by Myrddyn Phillips with the Introduction to the start of the Mapping Mountains publication of this list appearing on the 3^rd December 2015, and the list is now available in its entirety on Mapping Mountains in Google Doc format.

Y Trechol - The Dominant Hills of Wales by Myrddyn Phillips

The name the hill is listed by is Geirth Mawr, and it is adjoined to the Moel Hebog group of hills, which are situated in the north-western part of North Wales (Region A, Sub-Region A1), and it is positioned with the A497 road to its north and minor roads to its west and east, and has the town of Porthmadog towards the east.

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

When 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 with an estimated c 30m of drop, based on an estimated c 58m summit height, based on interpolation of 10m contouring and the 28m bwlch spot height that appears on the Ordnance Survey 1:25,000 Explorer map, resulting in a dominance value of 51.72%, which was sufficient for Dominant status.

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

Since the original publication of the Welsh P30 lists on Geoff Crowder’s v-g.me website there have been a number of maps made available online.  Some of these are historic such as the series of Six-Inch maps on the National Library of Scotland website.  Whilst others were digitally updated such as the Ordnance Survey Vector Map Local that was hosted on the Geograph website and which was entitled the Interactive Coverage Map, whilst others are current and digitally updated such as the interactive mapping on the Magic Maps and WalkLakes websites.

The details for this hill were re-assessed when the Ordnance Survey Vector Map Local hosted on the Geograph website and which was entitled the Interactive Coverage Map became available online.  This mapping had many spot heights not on other publicly available Ordnance Survey maps and for this hill it had a 56m summit spot height, resulting in its drop value being amended to 28m, which is insufficient for continued Dominant status.

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 deletion of this hill from Dominant status is due to LIDAR analysis, resulting in a 57.4m summit height and a 27.9m bwlch height, with these values giving this hill 29.5m of drop, which is insufficient for Dominant status.

Coed Bodlondeb (SH 779 781) - Dominant addition

There has been an addition to the listing of Y Trechol – The Dominant Hills of Wales due to detail included on the Ordnance Survey enlarged mapping hosted on the Geograph website.  This has resulted in the hill being added to the Dominant list.  With the criteria for inclusion to this list being those Welsh P30 hills whose prominence equal or exceed half that of their absolute height.

The details relating to this hill’s inclusion as a Dominant hill are retrospective as it appeared in the Carneddau group of hills when published on Mapping Mountains on the 17th December 2015.

Prior to this hill’s inclusion as a Dominant hill it was listed with an estimated c 27m of drop based on the Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps giving the hill an uppermost 50m ring contour and bwlch contouring between 20m – 30m, resulting in an estimated summit height of c 53m and an estimated bwlch height of c 26m.

The hill is in the Carneddau group of hills and is placed in the Region of North Wales (Region A, Sub-Region A1) and is situated on the outskirts of Conwy with the Afon Conwy to its immediate north and east.

If wanting to visit the hill it can be accessed relatively easily with public parking available next to where the Offices are marked to the south of the summit on Ordnance Survey maps.  There are a number of paths marked on the map that head up to, or contour around the summit, and as the name of the hill suggests it is part of a wood which consists of deciduous trees.

The name of the hill is Coed Bodlondeb and it is included as a Dominant hill as the Ordnance Survey enlarged map hosted on the Geograph website has contours at 5m intervals giving the hill an uppermost contour of 55m and bwlch contouring between 20m – 25m.  Therefore the summit is estimated as being c 57m high and the bwlch estimated as being c 23m high, with these values giving this hill c 34m of drop and 59.65% Dominance.

Since this hill was originally included in the Y Trechol - The Dominant Hills of Wales list the summit has been surveyed with the Trimble GeoXH 6000 and the bwlch of the hill has been analysed via LIDAR and the resulting values are given below.
