Mapping Mountains – Significant Height Revisions – The Fours – The 400m Hills of England

Cold Stones (SE 125 636) 

There has been a Significant Height Revision 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 prompted by Joe Nuttall who produced a summit analysis programme using LIDAR, and then confirmed by LIDAR analysis conducted by Myrddyn Phillips.

The criteria for the list this height revision affects 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 reclassified from 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 name the hill is listed by is Cold Stones, and it is adjoined to the Whernside group of hills, which are situated in the Yorkshire Dales, and it is positioned with the B6265 road to its north and a minor road to its west, and has the town of Pateley Bridge towards the east 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 included as a 400m Sub-Four and listed with an estimated c 26m of drop, based on an estimated c 417m summit height positioned at SE 120 641 and a 391m col height, the latter based on the spot height that appeared on the Ordnance Survey Vector Map Local hosted on the Geograph website and which was entitled the Interactive Coverage Map, with an accompanying note stating; The one that got away, or more appropriately, the one that was quarried away, as Cold Stones was once an English 400m P30, with an imperial height of 1,403ft (427.6m) recorded for the summit on the OS 1:10,560 map, with the OS enlarged Geograph map giving a height of 391m for the extant col, thereby confirming that the hill used to have 37m of drop.  The summit has been quarried leaving the highpoint of the hill at c 417m (SE 120 641) on the western rim of the former summit dome, thereby reducing the drop to c 26m and relegating the hill to Sub-Four 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.

LIDAR analysis gives the highest ground on this hill as 421.2m positioned at SE 12584 63663 and this comes within the parameters of the Significant Height Revisions used within this page heading, these parameters are:

The term Significant Height Revisions applies to any listed hill whose interpolated height and Ordnance Survey or Harvey map summit spot height has a 2m or more discrepancy when compared to the survey result produced by the Trimble GeoXH 6000 or analysis of data produced via LIDAR, also included are hills whose summit map data is missing an uppermost ring contour when compared to the data produced by the Trimble or by LIDAR analysis.

Therefore, the new listed summit height of this hill is 421.2m and this was derived from LIDAR analysis, this is 4.2m higher than its previously listed height of c 417m which was based on interpolation of 5m contouring that appeared on the OS Maps website.

Cold Stones (SE 125 636) 

There has been 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 prompted by Joe Nuttall who produced a summit analysis programme using LIDAR, and then confirmed by LIDAR analysis conducted by Myrddyn Phillips.

LIDAR analysis gives the highest ground on this hill as 421.2m positioned at SE 12584 63663 as opposed to 417.3m positioned at SE 12012 64046 for the previously listed summit, and this comes within the parameters of the Summit Relocations used within this page heading, these parameters are:

The term Summit Relocations applies to when the high point is positioned in a different field, to a different feature such as a conifer plantation, within a different map contour, a different point where a number of potential summit positions are within close proximity, when natural ground or the natural and intact summit is confirmed compared to a higher point such as a raised field boundary or covered reservoir that is considered a relatively recent man-made construct, or a relocation of approximately 100 metres or more in distance from either the position of a map spot height or from where the summit of the hill was previously thought to exist.

Therefore, the summit height produced by LIDAR analysis is 421.2m and this is positioned at SE 12584 63663.  This position is not given a spot height on the contemporary Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map, and is approximately 600 metres south-eastward from where the previously listed summit is positioned.

Mapping Mountains – Hill Reclassifications – The Fours

THIS HILL HAS SUBSEQUENTLY BEEN RECLASSIFIED TO FOUR STATUS

Cold Stones (SE 123 636) – 400m Sub-Four addition

There has been an addition to the listing of The Fours due to re-interpolation of Ordnance Survey map data coupled with studying Aerial maps and Google Street View.  The Fours is the title for the list of 400m hills of England and takes in all English hills at and above 400m and below 500m in height that have a minimum 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 24th April 2018.

Accompanying the main list of The Fours are three categories of sub hills, with this hill being an addition to the 400m Sub-Fours.  The criteria for 400m Sub-Four status are all English hills at and above 400m and below 500m in height that have 20m or more and below 30m of drop. 

  

The name of the hill is Cold Stones and prior to this re-interpolation of data the hill was listed with c 12m of drop, based on an uppermost 400m ring contour on the Ordnance Survey 1:25,000 Explorer map and a col spot height of 391m that appears on the Ordnance Survey Interactive Coverage Map hosted on the Geograph website.

Cold Stones once qualified for Four status and the details relating to this are given on page 41 of The Fours (Europeaklist December 2013) and are reproduced below:

Cold Stones (Section 35B)

The one that got away, or more appropriately, the one that was quarried away, as Cold Stones (SE 124 639), for which the Cardinal Hill is Whernside, was once an English 400m P30.  The hill appears on the OS 1:50,000 map number 99 and with an old imperial summit height of 1,403ft (427.6m) and a col height of 391m on the OS enlarged Geograoh map.  This hill once had 36.6m of drop.  Its summit has now been quarried, leaving the hill with an approximate c 12m of drop.

Cold Stones is situated in the Central Pennines area and is placed in Region 35, Section 35B, with its Cardinal Hill being Whernside (SD 738 814).  The hill is positioned above the B 6265 road which is to its immediate north and has the small community of Greenhow to its north-west, and as the remaining high point of the hill is a part of a working quarry permission to visit should be sought.

The re-interpolation of this hill’s map data is mainly based on contours on the Ordnance Survey 1:50,000 Landranger map and comparing these against those shown on the more detailed OS Maps which has recently replaced the OS Get-a-map, with the latter showing an uppermost 415m ring contour that doubles back on itself before closely packed contours continue downward to what is now the quarried remains of where the summit of this hill once stood.  These map contours are at odds with the uppermost 400m contour shown on the Ordnance Survey 1:25,000 Explorer map, however Aerial maps and Google Street View confirm what is left of the hill is much more than the 1:25,000 map suggests.

Therefore, Cold Stones is listed with a c 417m summit height and 391m col height, with these values giving this hill c 26m of drop, which is sufficient for it to be classified as a 400m Sub-Four.

The full details for the hill are:

Cardinal Hill:  Whernside

Summit Height:  c 417m

Name:  Cold Stones

OS 1:50,000 map:  99

Summit Grid Reference:  SE 123 636

Drop:  c 26m
