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


Pt. 438.3m (SD 650 808)

There has been a Significant Name Change to a hill that is listed in 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; 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 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 hill is adjoined to the Whernside group of hills, which are situated in the central Pennines, and it is positioned with the A 683 road to its west and the A 65 road to its south, and has the small town of Kirkby Lonsdale towards the south-west.

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 Brownthwaite Moss, and when the list was uploaded to the RHB Yahoo group file database the hill appeared under the name of Barbon Low Fell (Brownthwaite Moss).  The hill was subsequently listed as Brownthwaite in the 1st edition of The Fours when the list was published by Europeaklist in December 2013.

Hill list authors are prone to list a hill by the name that appears nearest to its summit on contemporary Ordnance Survey maps, without much consideration for its local or historical confirmation, or whether map placement is appropriate, and in the case of this hill the name of Brownthwaite Moss is applicable to wet land to the south-west of its summit, whilst Barbon Low Fell is recorded by Ordnance Survey as applicable to land to the north of this hill, and the name of Brownthwaite is given as applicable to the 419.8m high hill to the south-west which is positioned at SD 64761 80554.

Therefore, the name this hill is now listed by in The Fours - The 400m Hills of England is Pt. 438.3m and this follows the standard practice of using the point notation for a hill whose name has not been substantiated by the authors either through local enquiry, contemporary maps or from historical documentation.
