The Dodds: When Three Regional Lists Became One Metric Classification
Between 500 and 600 metres sits a collection of hills that used to be split across Deweys, Donald Deweys and Highland Fives—until the idea emerged in 2014 to unify them under a single name that works across Britain.
Vandeleur-Lynams and the 15-metre line between an Irish summit and a subsidiary top
The Vandeleur-Lynam list uses a 15-metre prominence threshold, low enough that it includes subsidiary tops alongside independent mountains. As at 31 December 2023 it contained 275 locations above 600 metres: 209 mountain summits, 14 hill summits just short of 2,000 feet, and 52 subsidiary tops with less than 30 metres of prominence.
The Deweys: hills that live in the gap between 500 metres and somebody else's problem
The Deweys are hills between 500 and 609.6 metres that existed in a classificatory blind spot until someone decided in 1995 that perfectly decent hills shouldn't be ignored just because they're not quite tall enough for the more famous lists.
The Furths: Britain's other 3000-footers
If you've ticked off Scotland's 282 Munros and need something to do with your weekends that doesn't involve developing an entirely new obsession, there are 34 more 3000-foot peaks scattered across Wales, England and Ireland that the Scottish Mountaineering Club has quietly been maintaining in their official tables since 1953.
Simms: the hill category that tidied up the lists
If you've ever wondered why British hill lists seem unnecessarily complicated, Simms offer a rare moment of clarity. Introduced by Alan Dawson in 2010, a Simm is any summit over 600 metres with at least 30 metres of drop all round – a definition that consolidated several older, overlapping lists like Murdos, Corbett Tops, Graham Tops and Hewitts into something more coherent.
The Donalds and Donald Tops: how the Scottish Lowlands got their own hill lists
The Scottish Mountaineering Club maintains two related but distinct classifications for Lowland hills over 2000 feet. Donald Tops include summits with at least 50 feet of drop, though those with less than 100 feet must also demonstrate sufficient topographical merit, while Donalds are a subset selected using an additional separation formula. Percy Donald's original tables started it all, giving the lower hills their own system separate from the famous Munros up north.
