Mapping Mountains – Hill Reclassifications – The 500-Metre Tops of England and Wales – Deweys

Bell Crags (NY 298 143) – Dewey addition

This is one in a series of retrospective Hill Reclassification posts that detail hills whose status has altered in the listing of the Deweys and where I have had direct association with the status change.  These posts will tie in with a forthcoming Change Register giving detail to this list and its alterations since publication in the Mountain tables book.

The 500-Metre Tops of England and Wales are affectionately known after their hill list compiler; Michael Dewey.  This list mixes metric and imperial height in its criteria to bookend up to the 2000ft height band and takes in all hills in England, Isle of Man and Wales that are 500m and above and below 2000ft (609.6m) in height that have 30m minimum drop.

This list formed one of a number of lists that appeared in the Mountain tables book published by Constable in 1995 and at the time of publication comprised 373 hills with 164 in England, 5 in the Isle of Man and 204 in Wales.  The Deweys have undergone extensive revision since first publication with the initial stages forming the basis of this revision given below:

1995    Mountain tables published by Constable with 373 hills listed as Deweys.

April 2000    Strider (LDWA quarterly booklet) publishes contact details for David Purchase and Myrddyn Phillips who have found and list 24 and 14 possible new 500m tops respectively.

It was expanded versions of the above two lists that formed the basis of the next publication:

25^th May 2000    List of Possible 500 Metre Tops by Michael Dewey listing 44 hills.

David Purchase expands his Additional Dewey 500m Hills and Myrddyn Phillips produces lists of English 500m hills to measure and Welsh 500m hills to measure.

These lists formed the basis of the next publication:

29^th June 2000    Possible/Probable 500’s by Michael Dewey listing 77 hills.  Michael adopts following protocol; if one person proposes that a top should qualify as a 500 by personal survey, and is then confirmed by a second person, it should then be promoted to the main list.

April 2002    The 500+ Tops of England and Wales – The ‘New Deweys’ published in the Strider booklet and listing 66 new qualifying hills.

25^th May 2006    Rob Woodall republishes Michael’s main and possible/probable lists on the RHB Yahoo group file database.

The details for this addition appear below:

The name the hill is listed by in the Deweys is Bell Crags, and it is adjoined to the Scafell group of hills which are situated in the Lake District in England, and it is positioned with the B5289 road to its west and the A591 road and Thirlmere Reservoir to its east, and has the town of Keswick towards the north.

This hill was not included in the original 1995 Constable publication, but with a 558m summit spot height and col contouring between 520m – 530m that appear on the Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer map, the interpolated drop value was estimated sufficient for this hill to be a potential new Dewey.

The above detail was noted by David Purchase and Myrddyn Phillips who worked independently but also exchanged all data, with David assessing the hill’s qualification on site.  These details were forwarded to the list author; Michael Dewey and the hill was added to the list on the 28^th July 2001.

As the interpolated drop value for this hill was close to the minimum 30m qualification for this list, the hill was prioritised for a GNSS survey, and this took place on the 30^th January 2010.  The summit and col of this hill were surveyed by John Barnard and Graham Jackson using a Leica 530, resulting in a 559.1m summit height and a 526.7m col height, with these values giving this hill 32.4m of drop, and confirming its Dewey status.
