The Relative Hills of Britain by Alan Dawson.
The HuMPs
HuMPs are hills of any height with a drop of 100 metres or more on all sides The name HuMP stands for HUndred Metre Prominence.
By definition, all Marilyns qualify as HuMPs (but not vice versa).
(HuMPs appear as Class=Hu on this website, or Ma if also a Marilyn).
The official e-book listing all the Humps, compiled by Mark Jackson, is now available for free download:

I have completed 1 (0%)
of 2167 HuMPs of Scotland. [Map *]159 (5.3%)

(Note: 3 hills which are Marilyn twin-tops count as separate HuMPs because they have over 100
reascent - these are An Stuc ,
Buidhe Bheinn
and Cruachan Dearg ).

Brief history and Acknowledgements
The original source for the HuMPs list was Dr Eric Yeaman's "Handbook of the Scottish Hills", published by Wafaida in 1989. In the
introduction the author states:
"For the purposes of this Handbook, a hill is defined as an eminence which
has an ascent of 100m all round or, failing that, is at least 5km (walking
distance) from any higher point on neighbouring hills."
In an attempt to clarify this list, Bernie Hughes set out to mirror the methodology that had produced the TACit Press "New Donalds"
from Percy Donald's original set, by removing Yeamans qualifying by distance alone, and applying a strict 100m height / 100m prominence rule.
Drop figures were obtained either from published sources such as TACit Tables where available, or from direct comparison of the 1:50,000
and 1:25,000 Ordnance Survey maps. The results were referred to as "New Yeamans".
Iain Cameron had previously produced an Excel spreadsheet of the hills in Yeaman's book, using the original publication's 4-figure
Grid Refs. Rob Woodall converted these to 6-figure Grid Refs, added drop data and suggested a few deletions e.g. where hills fell
short of the 5km distance rule. Clem Clements had applied Yeaman's original criteria to England and Wales, and christened the results
"Yeomans". Rob Woodall combined these data sources, and the results were amalgamated and uploaded to the RHB Yahoo community in the
Spring of 2007.
The name "HuMPs" (Hundred Metre Prominence) was originally proposed by Mark Jackson and unanimously accepted by the
RHB community . This data
was subsequently reworked and republished in a more accessible and attractive format by Mark in the summer of 2007, giving an
initial total of 2991 HuMPs. An early spate of promotions and demotions raised the total to 2993. Mark Jackson also initiated
the Hall of Fame for those climbing 2000+ HuMPs, in imitation of Alan Dawson's 600+ Marilyns Hall of Fame.
