The mountains in Scotland over 3,000 feet (914 metres) in height are called the Munros. Named after Hugh Munro, the first person to compile a list of them in 1891, there were were 283 munros. The list has grown and shrunk over the years, with the latest revision in September 2009 bringing the number back to 283 after Sgurr nan Ceannaichean was re-measured and found to miss the magic height by 1 metre.
