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 2nd 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
