THIS HILL HAS SUBSEQUENTLY BEEN DELETED FROM 400m SUB-FOUR STATUS
Burners Hills (NY 942 172) – 400m Sub-Four addition
There has been an addition to the listing of 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 detail on contemporary maps produced from Ordnance Survey
data.
This was initiated by Joe Nuttall who produced a summit analysis programme that used LIDAR with an alternative height map (DEM) allowing identification of summits and cols and thereby drops. The resulting spreadsheet that Joe produced
contains over 29600 hills.
This spreadsheet is being evaluated by a number of
people, including Ronnie Bowron, who passed the details of this hill for
evaluation.
The criteria for the list that this addition 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 added 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 2nd edition of the booklet containing this list was published by Mapping Mountains Publications on the 24th April 2018.
The Fours - The 400m Hills of England by Myrddyn Phillips and Aled Williams |
The name the hill is listed by is Burners Hills, and it is adjoined to the Cross Fell
group of hills, which are
situated in the Pennines of northern England (Region 35: The Northern and
Central Pennines, Section 35A: The Northern Pennines), and it is positioned
with the B6276 road to its north-west, the A66 road to its south and the B6277
road to its east, and has the town of Barnard Castle towards the east.
When the 2nd edition of the The Fours – The 400m Hills of England
was published by Mapping Mountains Publications in April 2018, this hill was
not classified but was listed with an estimated c 17m of drop, based on the 404m
summit spot height that appears on the Ordnance Survey 1:25,000 Explorer map
and an estimated c 387 col height based on interpolation of 5m contouring
between 385m – 390m that appeared on the OS Maps website.

The mapping on the OS Maps website is the
replacement for OS Get-a-map and has contours at 5m intervals which are proving
consistently more accurate compared to the 5m contours that sometimes appear on
Ordnance Survey 1:25,000 Explorer maps and used to appear on the online Vector
Map Local. This mapping is digitally updated
and has altered since the details for this hill were re-evaluated for the 2nd
edition of the booklet published in April 2018, as the col contouring is now
between 380m – 385m. This is not a one
off, as a number of examples have been noted where the contours on this mapping
have subsequently changed since first being evaluated. This re-assessment resulted in an estimated c
383m col height.

Therefore, the addition of Burners Hills to 400m
Sub-Four status is due to re-assessment of contemporary mapping produced from
Ordnance Survey data, resulting in a 404m summit height and a c 383m col height,
with these values giving this hill c 21m of drop, which is sufficient for 400m
Sub-Four status.

Our thanks to Joe Nuttall and Ronnie Bowron for bringing the
details of this hill to our attention.
