Hill list
Graham
Also called: Fiona
Definition
A Graham is a Scottish hill between 2,000ft (610m) and 2,500ft (762m) with at least 150 metres of drop on all sides. Currently 231 Grahams. Some older guidebooks call them Fionas after the original compiler.
Etymology & origin
Originally compiled in the early 1990s by Fiona Torbet (later Fiona Graham), the first woman to compleat the Munros and the Corbetts. Fiona built the list by hand from Ordnance Survey 1:50,000 maps before computer-aided survey made the process trivial. After her death in a car accident in 1993, the list was named after her — though Fiona herself preferred the term Fiona. Both names are accepted; the SMC uses Graham.
Context & usage
The Graham list is the most underrated in Scottish hillwalking. Stac Pollaidh (Graham, 612m) is the most-photographed peak in Scotland after the Cuillin; Suilven (731m, Graham) is one of the most distinctive mountains in Britain; Beinn an t-Sneachda above Glen Sligachan is the best Cuillin view that doesn't require scrambling. Yet because of the Munro-list dominance, Grahams see a fraction of the traffic that goes up Ben Lomond.
The 150m drop rule is more relaxed than the Corbett's 500ft rule, meaning the list includes more hills clustered around shared ridges. This makes Graham-bagging more about variety than commitment: many Graham days are shorter than the equivalent Munro day, and the list rewards regional exploration (the Outer Hebrides Grahams, the Skye Grahams, the Mull Grahams) more than the Munro grind.
Grahams are often the right answer for walkers building winter experience. Lower summits + shorter days + less serious avalanche terrain make them a better classroom for crampon and ice-axe technique than the higher Munros.
Related terms
Munro
A Munro is a Scottish mountain over 3,000ft (914.4m) in height with sufficient prominence to be considered a separate hill rather than a subsidiary summit. The current list contains 282 Munros, ranging from Ben Nevis (1,345m) to Beinn Teallach (915m). The list is maintained by the Scottish Mountaineering Club.
Corbett
A Corbett is a Scottish hill between 2,500ft (762m) and 3,000ft (914.4m) with at least 500ft (152m) of drop on all sides. The 500ft re-ascent rule separates Corbetts from subsidiary summits along the same ridge. There are 222 Corbetts in total.
Marilyn
A Marilyn is any British or Irish hill with at least 150 metres of topographic prominence — meaning it rises at least 150m above the lowest contour that separates it from any neighbour. Marilyns have no minimum height: a 200m coastal stack qualifies. 625 Scottish Marilyns; 2,011 in the full British and Irish list.
