Mapping Mountains – Hill Reclassifications – Humps


Coed-swydd (SO 139 646) – Hump reclassified to Subhump

This is the twelve in a series of Hill Reclassification posts that detail hills whose status has been altered in the listing of the Humps (HUndred Metre Prominences) through map study and / or surveys that I have instigated.

The hill name used in this and forthcoming posts is that used in the listing of Humps, therefore individual names and their composition may not match those that are used in listings I am directly associated with.  However, I am of firm belief that listed hill names used by other authors should be respected when giving detail within other people’s lists, however inappropriate some hill names or their composition may be considered.

This and forthcoming posts are retrospective as many of these hill reclassifications were initiated from studying the Ordnance Survey enlarged mapping that is hosted on the Geograph website, and for the reclassifications that affected the Humps the email I sent to Mark Jackson and copying in the DJM&M team in relation to this hill was dated 02.08.12.

The listing of Humps was published in book format by Lulu in 2009 and entitled More Relative Hills of Britain, its author; Mark Jackson gives credit to a number of people who contributed toward the formation of this list, these include; Eric Yeaman, Alan Dawson, Clem Clements, Rob Woodall, Bernie Hughes, Pete Ridges and others.  When the list was published in book format there were 2987 Humps listed with their criteria being any British hill that has 100m or more of drop, accompanying the main list is a sub category entitled Subhumps, with the criteria being any British hill that has 90m or more and below 100m of drop.

The details for the reclassification appear below:

There has been a reclassification to the listing of the Humps (HUndred Metre Prominences) due to consulting the Ordnance Survey enlarged mapping that is hosted on the Geograph website, with these details being sent to Mark Jackson on 02.08.12.

Prior to this notification Mark Jackson had listed this hill with c 100m of drop, based on the 412m summit spot height that appears on the Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps, and an estimated bwlch height of c 312m with its position being incorrectly placed.  However, with a 317m spot height appearing at the bwlch of this hill on the Ordnance Survey enlarged mapping hosted on the Geograph website it meant this hill had less than 100m of drop.  The summit and bwlch height of this hill was examined via Ordnance Survey 1:2,500 mapping with a 1350ft (411.5m) summit height and a 316.3m height at the bwlch confirming this hill has less than 100m of drop.

The hill currently appears under the composition of Coed-swydd in the Humps, having previously been listed as Pen Coed-swydd, and it is adjoined to the Elfael group of hills and is situated above the A 488 road which is to its north-west and the A 44 road to its south, with the small communities of Pen-y-bont towards the west south-west and Llandegley towards the south.

The reclassification of this hill from Hump to Subhump status was accepted by Mark Jackson and its new classification augmented in to the listing of the Humps in December 2012.
