Mapping Mountains – Hill Reclassifications – Humps

Moel Garegog (SJ 216 525) – Subhump addition

This is the twenty sixth 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 conducted.

Moel Garegog (SJ 216 525)

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, or in this instance from a survey with the Trimble GeoXH 6000, and for the reclassifications that affected the Humps the survey of this hill took place on the 22.08.14.

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) instigated by a survey with the Trimble GeoXH 6000 which took place on the 22.08.14.

Prior to the survey with the Trimble GeoXH 6000 Mark Jackson had listed this hill with 89m of drop based on the 413m summit spot height that appears on the Ordnance Survey 1:50,000 Landranger and 1:25,000 Explorer maps and a 324m spot height that appears on the A 525 road on the Ordnance Survey 1:25,000 Explorer map. 

The hill is adjoined to the Moel y Gamelin group of hills and is situated overlooking the A 5104 to its north-west and the A 525 road to its south-east, with the small community of Pen-y-stryt to the west south-west and Bwlchgwyn towards the east north-east.

Moel Garegog was surveyed using a Trimble GeoXH 6000 by Myrddyn Phillips on the 22.08.14 resulting in 90.1m drop value, with a summit height of 413.1m (converted to OSGM15) and a bwlch height of 323.0m (converted to OSGM15), with this drop value being sufficient for this hill to be classified as a Subhump.

The addition of this hill to Subhump status was accepted by Mark Jackson on the 22.09.14 and the listing of the Humps was updated accordingly.
