Making a mountain out of a moor hill
A Cumbrian hill has been declared a mountain after amateur surveyors found it was three quarters of an inch higher than originally thought.
It edged Thack Moor, north of Penrith, above the 2,000ft mark that signifies mountain status by Ordnance Survey's definition, reports the BBC.
Enthusiasts measured the mountain twice using high-tech GPS equipment. OS has now confirmed the measurements with its own analysis of the data.
Hill walkers John Barnard, Graham Jackson and Myrddyn Phillips are hobbyists who survey hills and mountains for fun.
They measured Thack Moor because the height according to OS maps was 609m - just short of the magic mountain mark. OS will now change its map readings to 610m.
Mr Barnard said: "We thought, is it or isn't it? And then the second time we went up and confirmed with the extra data, we were very pleased we'd located another 2,000 footer."
OS's Mark Greaves worked with the trio to confirm the measurements and said they were "very professional".
"They follow standard survey procedures. In fact they use the same equipment that our surveyors use," he said.
