It was in 1891 that Sir Hugh Munro - a founding member of the Scottish Mountaineering Club (SMC) - published a list of mountains of over 3000ft (914.4m) and which were sufficiently separated from neighbouring tops. Munro used nothing more than existing maps and an aneroid barometer, but his list of what would be called "the Munros" has not changed all that much over the years, especially since Munro failed to leave a clear definition. Some summits have been demoted and other Tops (lesser, subsidiary summits) promoted. The list is regularly revised. In 2016 the list stands at 282 Munros and 509 Tops. All of them are found exclusively in the Highlands.
Anyone "compleating" all 282 Munros can notify the Scottish Mountaineering Club and will be given a Compleation number in the SMC Journal.
Ironically, Sir Hugh Munro was not the first "Munro-bagger". He insisted on climbing not
only the Munros, but also the Tops, so on his death, he still had three to climb. The first one to bag all the Munros is Rev A E Robertson, who completed all of them in 1901. Since then many have followed his example.
The highest Munro is Ben Nevis with an altitude of 1345m (or to be precise: 1,345.527m). Number 282 in the list is Ben Vane (915m).
John Rooke Corbett was also a member of the SMC. He completed not only all Munros and Tops in 1930 but also all of Scotland's hills above 2000ft. He drafted a table of all hills between 2500ft and 3000ft with a drop of at least 500ft (so here we have a clear definition contrary to Munros where the definition is less clear-cut). For 2016, the list stands at 222 Corbetts. They are found all over Scotland.
A very well-known Corbett is
Ben Arthur, better known as "The Cobbler". It measures a decent 884m and is found a bit northwest of Loch Lomond.
Grahams are mountains between 2000 and 2499ft with a drop of at least 150m with another mountain. They were previously called Elsies (as in Lesser Corbetts - LCs), but when Fiona Torbet (née Graham) made a new list of all these hills, they were renamed in her honour.
There are 224 Grahams, with even seven islands containing Grahams.
The one you see to the left is Fiarach and is found close to Tyndrum.
Donalds are hills in Central or Southern Scotland of at least 2000ft with a drop of at least 30 metres all round. They were named after Percy Donald.
As they are found in only a part of Scotland, several Grahams are also Donalds.
