Mapping Mountains – Significant Name Changes – The Fours - The 400m Hills of England

 

The Fours - The 400m Hills of England – Significant Name Changes

The Fours - The 400m Hills of England are the English hills at and above 400m and below 500m in height that have 30m minimum drop.  Accompanying the main list are three sub lists; these are the 400m Sub-Fours, 390m Sub-Fours and 390m Double Sub-Fours.  With their criteria detailed in the Change Registers which are linked in the above titles.

The list is co-authored by Myrddyn Phillips and Aled Williams and the posts that have appeared on Mapping Mountains detailing the Significant Name Changes to the main P30 list and the sub lists appear below presented chronologically in receding order.

Postscript:  On the 10^th July 2024 the final group of hills in the updated version of this list were published on the Mapping Mountains site.  It was also announced that the sub hills accompanying the main listing of The Fours – The 400m Hills of England now take in just one category, this category is entitled the Sub-Fours.

Therefore, the 390m Sub-Fours and 390m Double Sub-Fours have been dispensed with and the criteria for the 400m Sub-Fours that included English hills at and above 400m and below 500m in height that have 20m and more and below 30m of drop, have been amended to include English hills at and above 400m and below 500m in height that have 15m and more and below 30m of drop and their title changed to the Sub-Fours.

Burton Howe (NZ 607 032) - 60th significant name change

Summit Relocations post for Burton Howe

 

There has been a Significant Name Change based on a summit relocation to a hill that is listed in the The Fours – The 400m Hills of England, with the summit height, col height and their locations, the drop and status of the hill derived from LIDAR analysis conducted by Myrddyn Phillips. 

LIDAR image of Burton Howe (NZ 607 032) 

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

The Fours – The 400m Hills of England - English hills at or above 400m and below 500m in height that have 30m minimum drop, accompanying the main list is a sub list entitled the Sub-Fours, the criteria for which are all English hills at or above 400m and below 500m in height that have 15m or more and below 30m of drop.  The list is co-authored by Myrddyn Phillips and Aled Williams and is available to download in Google Doc format from the Mapping Mountains site.

The Fours - The 400m Hills of England by Myrddyn Phillips and Aled Williams

The hill is adjoined to the Urra Moor group of hills, which are situated in the North York Moors of north-eastern England, and it is positioned with minor roads to its north and east, and the B1257 road to its west, and has the town of Stokesley towards the north-west.

When the Introduction to the first group of hills for the updated and revised listing of the The Fours – The 400m Hills of England was published by Mapping Mountains on the 10^th September 2022, it was announced that the accompanying sub lists were being revised with the two 390m categories dispensed with and the criteria and name of the 400m Sub-Fours revised.  The one accompanying sub list is now named the Sub-Fours with its criteria being all English hills 400m and above and below 500m in height that have 15m and more and below 30m of drop.

Prior to this revision this hill was listed under the name of Greenhow Moor with 17m of drop, based on the 432m summit spot height positioned at NZ 61114 02607 and the 415m col spot height that appear on the Ordnance Survey 1:25,000 Explorer map.

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.

LIDAR analysis gives the highest ground on this hill as 432.3m positioned at NZ 60792 03254, with LIDAR giving its originally listed summit position as 432.2m positioned at NZ 61049 02611 and NZ 61062 02608 and NZ 61063 02601 and NZ 61063 02599 and NZ 61080 02598.

Therefore, the name this hill is now listed by in The Fours - The 400m Hills of England is Burton Howe and this was instigated from a summit relocation. 

 

The full details for the hill are:

Group:  Urra Moor

Name:  Burton Howe

Previously Listed Name:  Greenhow Moor

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

The Fours – The 400m Hills of England - English hills at or above 400m and below 500m in height that have 30m minimum drop, accompanying the main list is a sub list entitled the Sub-Fours, the criteria for which are all English hills at or above 400m and below 500m in height that have 15m or more and below 30m of drop.  The list is co-authored by Myrddyn Phillips and Aled Williams and is available to download in Google Doc format from the Mapping Mountains site.

The Fours - The 400m Hills of England by Myrddyn Phillips and Aled Williams

The hill is adjoined to the Axe Edge group of hills, which are situated in the Peak District, and it is positioned with minor roads to its north, west and east, and the A53 road farther to its west, and has the town of Buxton towards the north north-east.

When the Introduction to the first group of hills for the updated and revised listing of the The Fours – The 400m Hills of England was published by Mapping Mountains on the 10^th September 2022, it was announced that the accompanying sub lists were being revised with the two 390m categories dispensed with and the criteria and name of the 400m Sub-Fours revised.  The one accompanying sub list is now named the Sub-Fours with its criteria being all English hills 400m and above and below 500m in height that have 15m and more and below 30m of drop.

Prior to this revision this hill was listed under the point (Pt. 448m) notation with an estimated c 15m of drop, based on the 448m summit spot height that appears on the Ordnance Survey 1:25,000 Explorer map and an estimated c 433m col height, based on interpolation of 5m contouring between 430m – 435m. 

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

Since the compilation of this list 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, and it is the series of Ordnance Survey Six-Inch maps that form the basis of the change in the listed name of this hill.

The Ordnance Survey series of Six-Inch maps formed the base map Ordnance Survey used for many decades leading to the production of the 1:10,000 Series of maps, both have now been superseded by the digitised Master Map.  The series of Six-Inch maps are excellent for name placement and especially so compared to the contemporary Ordnance Survey 1:25,000 Explorer map, and it is the series of Six-Inch maps that position the name of Brand Side adjacent to land where the summit of this hill is situated.

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

The Fours – The 400m Hills of England - English hills at or above 400m and below 500m in height that have 30m minimum drop, accompanying the main list is a sub list entitled the Sub-Fours, the criteria for which are all English hills at or above 400m and below 500m in height that have 15m or more and below 30m of drop.  The list is co-authored by Myrddyn Phillips and Aled Williams and is available to download in Google Doc format from the Mapping Mountains site.

The Fours - The 400m Hills of England by Myrddyn Phillips and Aled Williams

The hill is adjoined to the Great Shunner Fell group of hills, which are situated in the English Pennines, and it is positioned with minor roads to its north-east, west and south-east, and the B6270 road farther to its south, and has the village of Reeth towards the west south-west.

When the Introduction to the first group of hills for the updated and revised listing of the The Fours – The 400m Hills of England was published by Mapping Mountains on the 10^th September 2022, it was announced that the accompanying sub lists were being revised with the two 390m categories dispensed with and the criteria and name of the 400m Sub-Fours revised.  The one accompanying sub list is now named the Sub-Fours with its criteria being all English hills 400m and above and below 500m in height that have 15m and more and below 30m of drop.

Prior to this revision this hill was listed as Fremington Edge with 17m of drop, based on the twin 435m summit spot heights positioned at SE 05216 99905 that appears on the Ordnance Survey 1:25,000 Explorer map and positioned at NZ 05189 00016 that appeared on the Ordnance Survey Vector Map Local hosted on the Geograph website and which was entitled the Interactive Coverage Map, and the 418m col spot height that appears on the Ordnance Survey 1:25,000 Explorer map.

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.

LIDAR analysis gives the highest ground on this hill as 435.5m positioned at NZ 05203 00071.  The hill was therefore listed under the name of Fremington Edge with these details given for the summit position and height when the revised list including P15 subs was subsequently published.

After these details became publicly available Ronnie Bowron sent communication that the listed summit was to a spoil heap with the track of a recent walk over these high points and a photo of the spoil heap attached and that the locally known name for the hill is Copperthwaite Moor.  Ronnie explained that he knows this area very well, and as a teenager used to go to scout camp directly below the edge; the edge being Fremington Edge which is a prominent feature of this hill.

Since the original publication of this list 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 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.

One of the mapping resources now available online is the WalkLakes website which hosts an interactive map originated from the Ordnance Survey Open Data programme.  And although the contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map do not record the specific name of Copperthwaite Moor, the WalkLakes map does. 

Extract from the interactive mapping hosted on the WalkLakes website

Therefore, the name this hill is now listed by in The Fours - The 400m Hills of England is Copperthwaite Moor and this was derived from Ronnie Bowron, with the name also recorded on the WalkLakes interactive map. 

 

The full details for the hill are:

Cefn Bach (SO 270 390) - 54th significant name change

 

There has been a Significant Name Change to a hill that is listed in the The Fours – The 400m Hills of England, with the summit height, col height and their locations, the drop and status of the hill derived from LIDAR analysis conducted by Aled Williams and Myrddyn Phillips.

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

The Fours – The 400m Hills of England.  English hills at or above 400m and below 500m in height that have 30m minimum drop, accompanying the main list is a sub list entitled the Sub-Fours, the criteria for which are all English hills at or above 400m and below 500m in height that have 15m or more and below 30m of drop.  The list is co-authored by Myrddyn Phillipsand Aled Williams and is available to download in Google Doc format from the Mapping Mountains site.

The Fours - The 400m Hills of England by Myrddyn Phillips and Aled Williams

The hill is adjoined to the Waun Fach group of hills, which are situated in the county of Herefordshire close to the Welsh border, and it is positioned with minor roads to its north-east and south-west, and the B4348 road farther to its north, and has the town of Y Gelli Gandryll (Hay-on-Wye) towards the north-west. 

Extract from the Ordnance Survey 1:50,000 Landranger map

When the listing that later became known as the The Fours – The 400m Hills of England was first compiled this hill appeared under the name of Cefn Hill, which is a prominent name that appears beside the summit of the hill on the Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map.  And it was this name that the hill was listed as when the 1^st edition of the list was published by Europeaklist in December 2013 and when the 2^nd edition of the list was published by Mapping Mountains Publications in April 2018. 

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

The intricacies of language and prioritising one in favour of another for listing a hill is fraught with complication, with originating Cymraeg names being anglicised and also originating English names being cymricised, examples such as these are more common in border country and especially so for anglicised forms.  There is no steadfast rule that fits all, but as a standard a name that has its origins in the Welsh language and where this is substantiated by either historic documentation and/or contemporary usage should be prioritised in favour of a contemporary anglicised or part or whole English version of the name.

The listed name of this hill was reviewed by Aled Williams for the July 2024 publication of this list by Mapping Mountains and was subsequently altered with the following appearing in the Notes section accompanying its listing:

Name is documented in numerous sources as Cefn Bach up until at the least the mid-19^th century, although Cefn Hill may now be the local form in use.

Therefore, the name this hill is now listed by in The Fours - The 400m Hills of England is Cefn Bach and this was derived from a numer of documented sources up until at least the mid-19^th century.

Summit Relocations post for Ale Oak Bank

 

There has been a Significant Name Change to a hill that is listed in the The Fours – The 400m Hills of England, with the summit height, col height and their locations, the drop and status of the hill derived from LIDAR analysis initially conducted by Aled Williams and subsequently by Myrddyn Phillips.

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

The Fours – The 400m Hills of England.  English hills at or above 400m and below 500m in height that have 30m minimum drop, accompanying the main list is a sub list entitled the Sub-Fours, the criteria for which are all English hills at or above 400m and below 500m in height that have 15m or more and below 30m of drop.  The list is co-authored by Myrddyn Phillipsand Aled Williams and is available to download in Google Doc format from the Mapping Mountains site.

The Fours - The 400m Hills of England by Myrddyn Phillips and Aled Williams

The hill is adjoined to the Cilfaesty group of hills, which are situated in the county of Shropshire close to the Welsh border, and it is positioned with minor roads to its north-east and north-west, and the B4368 road to its south-west, and has the town of Clun towards the east south-east.

During the updating of the The Fours – The 400m Hills of England prior to the 1^st edition publication by Europeaklist in December 2013, this hill was provisionally listed by Myrddyn Phillips under the transposed name of Clun Forest, which was a prominent name that appeared near its summit on the Ordnance Survey Vector Map Local hosted on the Geograph website and which was entitled the Interactive Coverage Map. 

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

Since the original compilation of this list 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 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.  One of the historic maps now available online is the Ordnance Survey Draft Surveyors map which formed the basis for the first publicly available Ordnance Survey One-Inch ‘Old Series’ map, and it is the Draft Surveyors map that formed the basis of the initial change in the listed name of this hill.

The Draft Surveyors maps consist of the preliminary drawings made by the Ordnance Survey surveyors between the 1780s and 1840 and formed the basis for the first publicly available One-Inch map.  They were drawn at scales of six inches to the mile for areas considered of particular military significance and down to two inches to the mile for other areas.  Fair copies were then produced from these preliminary drawings to one inch to the mile and then copper plates were prepared for printing.  The Draft Surveyors maps for the whole of Wales and its border country are now available online and they form an important part in the study of Welsh upland place-names as they bridge the time frame between the late 18^th century and the mid-19^th century when the Ordnance Survey produced their first One-Inch maps, and it is this map that places the name Fron Hill close to the summit of this hill. 

Extract from the Ordnance Survey Draft Surveyors map

Consequently, this hill appeared under the name of Fron Hill when the 1^st edition of The Fours was published by Europeaklist in December 2013 and the 2^nd edition of The Fours – The 400m Hills of England was published by Mapping Mountains Publications in April 2018.

The listed name of this hill was reviewed by Aled Williams for the July 2024 publication of this list by Mapping Mountains and was subsequently altered with the following appearing in the Notes section accompanying its listing:

Name taken from 1847 inclosure award. The place-name Ale Oak is a rendering of the originating Welsh name Derwen y Cwrw. The land-name Fron Hill recorded in 1816 (OS) may only apply to the western hillside, which is recorded as Fron Aber Dwynant in the 1847 inclosure award.

Therefore, the name this hill is now listed by in The Fours - The 400m Hills of England is Ale Oak Bank and this was derived from the 1847 inclosure award. 

 

The full details for the hill are:

On the 10^th July 2024 the Sub hills accompanying the main listing of the The Fours – The 400m Hills of England were amended.  The 390m Sub-Fours and 390m Double Sub-Fours have been dispensed with, and the remaining 400m Subs are now entitled the Sub-Fours and their criteria amended to include all English hills at and above 400m and below 500m in height that have 15m and more and below 30m of drop.

The Fours - The 400m Hills of England by Myrddyn Phillips and Aled Williams

The hill is the highest point in its own group and therefore the group takes on its name; the Bron Wennyly group of hills, which are situated in Bodmin Moor in the south-west of the country, and it is positioned with a minor road to its north, the A39 road to its north-west, the B3266 road to its west and the A30 road to its south-east, and has the town of Camelford towards the north-west.

When the listing that is now known as The Fours – The 400m Hills of England was originally compiled by Myrddyn Phillips this hill appeared under the name of Brown Willy; which is a prominent name that appears close to the summit of this hill on the contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map, and this was also the name the hill appeared as when the list was uploaded to the RHB Yahoo group file database.

The intricacies of language and prioritising one in favour of another for listing a hill is fraught with complication, however as a general protocol the authors prioritise originating names for languages such as Cornish over their anglicised versions.

Therefore, the name this hill is now listed by in The Fours - The 400m Hills of England is Bron Wennyly, with the prioritised language protocol being used and the spelling following that recommended in Standard Written Form which is adopted by the Cornish Language Partnership for educational and official use.

Mapping Mountains - Significant Name Changes - The Fours - The 400m Hills of England

Swell Tor (SX 559 733) - 45th significant name change

 

There has been a Significant Name Change that is retrospective to a hill that is listed in the The Fours – The 400m Hills of England, with the summit height, col height and their locations, the drop and status of the hill derived from LIDAR analysis initially conducted by Aled Williams and subsequently by Myrddyn Phillips. 

LIDAR image of Swell Tor (SX 559 733)

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

The Fours – The 400m Hills of England.  English hills at or above 400m and below 500m in height that have 30m minimum drop, accompanying the main list are three categories of sub hills, with this hill being included in the 400m Sub-Four category, the criteria for which are all English hills at or above 400m and below 500m in height that have 20m or more and below 30m of drop.  The list is co-authored by Myrddyn Phillips and Aled Williams and the 2^nd edition of the booklet containing this list was published by Mapping Mountains Publications on the 24^th April 2018.

The Fours - The 400m Hills of England by Myrddyn Phillips and Aled Williams

The hill is adjoined to the High Willhays group of hills, which are situated in Dartmoor in the south-west of the country, and it is positioned with the B3357 road to its north, a minor road to its west south-west and the B3212 road to its south-east, and has the town of Tavistock towards the west.

When the listing that is now known as The Fours – The 400m Hills of England was originally compiled by Myrddyn Phillips this hill appeared under the directional name of King’s Tor South-east Top, with an accompanying note stating; Author’s name from tor to the North-west. 

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

During the original compilation of this list the author 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 or as in this instance use a directional name based on supplanting the name of a near hill and adding a directional component to it.  This is not a practice that is now advocated as with time and inclination place-name data can be improved either by asking local people or by examining historic documents, through this form of research an appropriate name for the hill can usually be found.

The title page

When the 1^st edition of the The Fours now co-authored by Myrddyn Phillips and Aled Williams was published by Europeaklist in December 2013, this hill was listed under the name of Swell Tor with an accompanying note stating; Name recorded as Swell Tor and Swill Tor in A Description of the Part of Devonshire Bordering on the Tamar and the Tavy by A. E. Bray (1836). 

Extract from the book

Therefore, the name this hill is now listed by in The Fours - The 400m Hills of England is Swell Tor, and this was derived from the book entitled A Description of the Part of Devonshire Bordering on the Tamar and the Tavy which is authored by A. E. Bray and first published in 1836.

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

The Fours – The 400m Hills of England.  English hills at or above 400m and below 500m in height that have 30m minimum drop, accompanying the main list are three categories of sub hills, these are the 400m Sub-Fours, the 390m Sub-Fours and the 390m Double Sub-Fours.  The list is co-authored by Myrddyn Phillips and Aled Williams and the 2^nd edition of the booklet containing this list was published by Mapping Mountains Publications on the 24^th April 2018.

The Fours - The 400m Hills of England by Myrddyn Phillips and Aled Williams

The hill is adjoined to the Dunkery Beacon group of hills, which are situated in the counties of Somerset and Devon, and it is positioned with a minor road to its north-west and east, the A39 road to its north, the B3223 road to its west and the B3224 road to its south, and has the village of Porlock towards the north-east.

When the listing that is now known as The Fours – The 400m Hills of England was originally compiled this hill appeared under the name of Black Mires; which is a prominent name that appears close to its summit on the contemporary Ordnance Survey 1:25,000 Explorer map, and this was also the name it appeared as when the list was uploaded to the RHB Yahoo group file database. 

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

Since the original compilation of this list 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.  Two of the historic maps now available online are the Ordnance Survey Draft Surveyors map and the Ordnance Survey One-Inch ‘Old Series’ map, and it is these maps coupled with detail on the Ordnance Survey series of Six-Inch maps that formed the basis in the change in the listed name of this hill.

The Draft Surveyors maps consist of the preliminary drawings made by the Ordnance Survey surveyors between the 1780s and 1840 and formed the basis for the first publicly available One-Inch map.  They were drawn at scales of six inches to the mile for areas considered of particular military significance and down to two inches to the mile for other areas.  Fair copies were then produced from these preliminary drawings to one inch to the mile and then copper plates were prepared for printing.  The Draft Surveyors maps are now available online and they bridge the time frame between the late 18^th century and the mid-19^th century when the Ordnance Survey produced their first One-Inch maps.

The One-Inch ‘Old Series’ map was the first map that Ordnance Survey produced, and their publication culminated from the whole of Britain being surveyed between 1791 and 1874 and the detail gathered therein produced at a scale of one inch to the mile and published in sheet format between 1805 and 1874.  The One-Inch ‘Old Series’ maps are now available online; they are also available in map format as enlarged and re-projected versions to match the scale and dimensions of the Ordnance Survey 1:50,000 Landranger series and are published by Cassini.  This series of maps form another important part in the study of upland place-names and bridge the timeframe leading up to the production of the Ordnance Survey base map of the Six-Inch series.  Importantly for this hill and its listed name, it is these two maps that give the name Lucott Hill applying to this hill. 

Extract from the Ordnance Survey series of Six-Inch maps

The Ordnance Survey series of Six-Inch maps formed the base map Ordnance Survey used for many decades leading to the production of the 1:10,000 Series of maps, both have now been superseded by the digitised Master Map.  The series of Six-Inch maps are excellent for name placement and especially so compared to the contemporary Ordnance Survey 1:25,000 Explorer map, and it is the series of Ordnance Survey Six-Inch maps that give the name Lucott Moor applying to land incorporating the summit of this hill. 

Extract from the Ordnance Survey 1:50,000 Landranger map

Therefore, the name this hill is now listed by in The Fours - The 400m Hills of England is Lucott Moor and this was derived from a variety of Ordnance Survey maps, including the series of Six-Inch maps and the contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map.

The Fours - The 400m Hills of England by Myrddyn Phillips and Aled Williams

The hill is adjoined to the Dunkery Beacon group of hills, which are situated in the counties of Somerset and Devon, and it is positioned with the A39 road to its north-west and the B3358 road to its south, and has the small community of Parracombe towards the west north-west.

When the 1^st edition of the The Fours was published by Europeaklist in December 2013, the qualifying 400m Sub-Four hill was listed as Wood Barrow (SS 716 425) with 22m of drop, based on the 480m summit spot height that appears on the contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map and the 458m col spot height that appears on the contemporary Ordnance Survey 1:25,000 Explorer map, with an accompanying note stating:

Although Chapman Barrows at SS 700 434 has a 480m map height, it is not listed as a twin Sub-Four as its 480.093m flush bracket height means ground at the base of the trig pillar will be below 480m. 

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

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.

The height produced by initial LIDAR analysis to the high point of Chapman Barrows is 479.8m positioned at SS 70003 43472 and to the high point of Wood Barrow is 479.7m positioned at SS 71627 42506, resulting in the summit of the qualifying 400m Sub-Four being relocated from Wood Barrow to Chapman Barrows.

However, the latest available LIDAR analysis gives the high point of Chapman Barrows as 479.8m positioned at SS 70003 43471 and the high point of Wood Barrow as 480.0m positioned at SS 71627 42505, resulting in the summit of the qualifying 400m Sub-Four being relocated back from Chapman Barrows to Wood Barrow.

Therefore, the name this hill is now listed by in The Fours - The 400m Hills of England is Wood Barrow and this was instigated from a summit relocation.

Since the original compilation of this list 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.  One of the historic maps now available online is the Ordnance Survey Draft Surveyors map which formed the basis for the first publicly available Ordnance Survey One-Inch ‘Old Series’ map, and it is the Draft Surveyors map that forms the basis in the change in the listed name of this hill. 

Extract from the Ordnance Survey Draft Surveyors map

The Draft Surveyors maps consist of the preliminary drawings made by the Ordnance Survey surveyors between the 1780s and 1840 and formed the basis for the first publicly available One-Inch map.  They were drawn at scales of six inches to the mile for areas considered of particular military significance and down to two inches to the mile for other areas.  Fair copies were then produced from these preliminary drawings to one inch to the mile and then copper plates were prepared for printing.  The Draft Surveyors maps for the whole of Wales are now available online and they form an important part in the study of Welsh upland place-names as they bridge the time frame between the late 18^th century and the mid-19^th century when the Ordnance Survey produced their first One-Inch maps, and importantly for this hill and its listed name, it is this map that names the hill as Fron Hill.

Consequently, this hill appeared under this name when the 1^st edition of The Fours was published by Europeaklist in December 2013 and the 2^nd edition of The Fours – The 400m Hills of England was published by Mapping Mountains Publications in April 2018.

Therefore, the name this hill is now listed by in The Fours - The 400m Hills of England is Fron Hill and this was derived from the Ordnance Survey Draft Surveyors map.

Mapping Mountains - Significant Name Changes - The Fours - The 400m Hills of England

The Beet (SK 122 819) - 38th significant name change

 

There has been a Significant Name Change that is retrospective to a hill that is listed in the The Fours – The 400m Hills of England, with the summit height, col 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:

The Fours – The 400m Hills of England.  English hills at or above 400m and below 500m in height that have 30m minimum drop, accompanying the main list are three categories of sub hills, these are the 400m Sub-Fours, the 390m Sub-Fours and the 390m Double Sub-Fours.  The list is co-authored by Myrddyn Phillips and Aled Williams and the 2^nd edition of the booklet containing this list was published by Mapping Mountains Publications on the 24^th April 2018.

The Fours - The 400m Hills of England by Myrddyn Phillips and Aled Williams

The hill is adjoined to the Kinder Scout group of hills, which are situated in the Peak District, and it is positioned with a minor road to its north-west, the A623 road to its south-west and the B6049 road to its east, and has the town of Chapel-en-le-Frith towards the west.

When the listing that is now known as The Fours – The 400m Hills of England was originally compiled this hill appeared under the transposed and invented name of Slitherstone Hill, with an accompanying note stating; Authors name from mine to the south.

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.  And for this hill its listed name was transposed from a disused quarry with the word Hill added to it.  This is not a practice that is now advocated as with time and inclination place-name data can be improved either by asking local people or by examining historic documents, through this form of research an appropriate name for the hill can usually be found.

Since the original publication of this list 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.  One of the historic maps now available online is the Ordnance Survey One-Inch ‘Old Series’ map, and it is this map that formed the basis for the change in the listed name of this hill.

The One-Inch ‘Old Series’ map was the first map that Ordnance Survey produced, and their publication culminated from the whole of Britain being surveyed between 1791 and 1874 and the detail gathered therein produced at a scale of one inch to the mile and published in sheet format between 1805 and 1874.  The One-Inch ‘Old Series’ maps for the whole of Wales are now available online; they are also available in map format as enlarged and re-projected versions to match the scale and dimensions of the Ordnance Survey 1:50,000 Landranger series and are published by Cassini.  This series of maps form another important part in the study of upland place-names and bridge the timeframe leading up to the production of the Ordnance Survey base map of the Six-Inch series, and importantly for this hill and its listed name, it is this map that places the name of The Beet across the summit area of this hill.

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

The Fours – The 400m Hills of England.  English hills at or above 400m and below 500m in height that have 30m minimum drop, accompanying the main listing of The Fours are three categories of sub hills, with this hill reclassified to the 400m Sub-Four category, the criteria for which are all English hills at or above 400m and below 500m in height that have 20m or more and below 30m of drop.  The list is co-authored by Myrddyn Phillips and Aled Williams and the 2^nd edition of the booklet containing this list was published by Mapping Mountains Publications on the 24^th April 2018.

The Fours - The 400m Hills of England by Myrddyn Phillips and Aled Williams

The hill is adjoined to the Axe Edge group of hills, which are situated in The Southern Pennines (Region 36), and it is positioned with the A515 road to its south and a minor road to its east, and has the town of Buxton towards the north-west.

When the 2^nd edition of the The Fours – The 400m Hills of England was published by Mapping Mountains Publications in April 2018, this hill was listed as Nether Low with a summit height of 414m based on the spot height that appears on the Ordnance Survey 1:25,000 Explorer map and which is positioned at SK 11076 68874, with an accompanying note stating; A potential higher summit has been reported by a number of people, including Adrian Rayner and Carole Engel and is positioned at SK 10994 67973.

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. 

LIDAR analysis gives the highest ground on this hill as 414.7m positioned at SK 10999 67962.  Therefore, this is a significant name change based on the qualifying summit having been relocated from the originally listed summit of Nether Low, and as an appropriate name for this hill has not been found by the authors either from historical and/or local research, the listing protocol is to use the point (Pt. 414.7m) notation. 

Therefore, the name this hill is now listed by in The Fours - The 400m Hills of England is Pt. 414.7m and this was instigated from a summit relocation.

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

The Fours – The 400m Hills of England.  English hills at or above 400m and below 500m in height that have 30m minimum drop, accompanying the main listing of The Fours are three categories of sub hills, with this hill being included in the 400m Sub-Four category, the criteria for which are all English hills at or above 400m and below 500m in height that have 20m or more and below 30m of drop.  The list is co-authored by Myrddyn Phillips and Aled Williams and the 2^nd edition of the booklet containing this list was published by Mapping Mountains Publications on the 24^th April 2018.

The Fours - The 400m Hills of England by Myrddyn Phillips and Aled Williams

The hill is adjoined to the The Cheviot group of hills, which are situated in Northumberland (Region 33: Scottish Border to the River Tyne), and it is positioned with a minor road to its north and the A697 road to its east, and has the town of Wooler towards the north north-east.

When the 2^nd edition of the The Fours – The 400m Hills of England was published by Mapping Mountains Publications in April 2018, this hill was not included in the accompanying sub list, as it was considered not to meet the criteria used for this sub category.

However, during the updating of this list for the 2^nd edition this hill was noted and listed as Broad Moss with 18m of drop, based on the 432m summit spot height positioned at NT 95699 21058 that appears on the Ordnance Survey 1:50,000 Lanranger and 1:25,000 Explorer map and the 414m col spot height that appeared on the Ordnance Survey Vector Map Local hosted on the Geograph website and which was entitled the Interactive Coverage Map.

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.

LIDAR analysis gives the higher summit to Long Crags positioned at NT 95597 21432, therefore this is a significant name change based on the qualifying summit having been relocated from the originally listed summit of Broad Moss.

Therefore, the name this hill is now listed by in The Fours - The 400m Hills of England is Long Crags and this was instigated from a summit relocation.
