The HuMPs.
HuMPs take Dawson's prominence idea a step further down the hillside. A HuMP — the name stands for “HUndred Metre Prominence” — is any hill, of any height, with at least 100 m of drop on all sides. Because every Marilyn (150 m of drop) automatically qualifies, the Marilyns are listed separately above, and this list covers the remaining HuMPs: the smaller but still genuinely independent summits, counted across Britain. The full set was collated by Mark Jackson from the work of many hill surveyors and published in 2009. Like the Marilyns they range across the whole country; shown here are the Lakeland HuMPs.
Mark Jackson proposed the HuMPs as a gentler companion to Alan Dawson's Marilyns, gathering data from across the Relative Hills community and publishing the definitive list in More Relative Hills of Britain (2009). He also started a Hall of Fame for those who climb 1,200 or more, echoing Dawson's Marilyn Hall of Fame.
