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.

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 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.

Why are so many Welsh valleys called Cwm?

If you've looked at a map of Wales, you'll have noticed cwm cropping up everywhere—Cwm Idwal, Cwm Rhondda, and dozens more. It's the Welsh word for a valley or cirque, and in place names it's typically followed by whatever distinguishes that particular cwm from all the others: a person, a feature, or just what it looks like. Simple enough, once you know what you're looking at.

The Wild Camping Grey Area: Where You Can, Where You Can't, and Why Scotland's Different

Britain's wild camping laws are a proper muddle: you generally need permission in England and Wales, Dartmoor's commons offer a genuine legal right to pitch, and Scotland grants access across most land under its own statute. The confusion comes from assuming that permission to walk somewhere includes permission to sleep there, which it usually doesn't, and the legal ground shifts beneath your boots without so much as a signpost to warn you.
