Any hill given a dishonourable mention by more than one bagger becomes a candidate for the Marilyn Hall of Shame, a virtual home for insane hills. Currently in residence are Mochrum Fell (27C), Woodhead Hill (27C), Myarth (32A), Hensbarrow Beacon (40), Dundry Down (41) and Crowborough (42). But madness is a vague meaningless term for a complex range of symptoms. There would seem to be at least six main categories of affliction:
Excess Tree Density: Mochrum Fell, Woodhead Hill, Mynydd Marchywel, Hill of the Wangie, Staple Hill etc.
Get Off My Land: Caeliber Isaf, Carnedd Wen, Carnmenellis, Myarth, Saxa Vord etc.
Big Boring Bogs: Creag nam Fiadh, Creag Loisgte, Meallan a'Chaise and many others. Some have good views though.
Dull But Painless: Botley Hill, Christ Cross, Hegdon Hill
Strangely Strange But Oddly Normal: Crowborough, Dundry Down, Hensbarrow Beacon, Great Orme.
Bloody Impossible: Stac Lee, Stac an Armin.
Some of these may recuperate and be released for the benefit of the community, but others will no doubt take their place.
Hills with summits so flat that it is difficult to identify their highest point (eg Hailstorm Hill, Mickle Fell, Black Mountain) do not qualify for the Hall of Shame if they are otherwise acceptable. Also disqualified are hills which happened to be unpleasant because it rained, or you forgot your lunch, or had a row, or got lost, or fell off....
