A hill in the Lake District has been reclassified as a mountain after a survey found that it was three feet taller than originally thought.
Miller Moss, in the northern hills of the Lake District, was originally recorded as 609 meters high, 600 centimeters below the threshold to be counted as a mountain.
However, on August 1, independent inspectors John Barnard and Graham Jackson used modern equipment to discover that Miller Moss was actually 610.1 meters tall, classifying it as a mountain.
Because of this, Miller Moss will become mountain 446 on the list of The Mountains of England and Wales, by Anne and John Nuttall, according to The Times.
The topography of the mountain involved a walk of five kilometers in each direction while transporting 6 kg of equipment.
He took Mr. Barnard and Mr. Jackson eight hours in total.
Ordnance Survey has already accepted the observation, which means that it will have to modify its maps to take into account the new height of the hill.
It is not the first hill that the couple has reclassified. They are now responsible for 30 modifications to the Land Ranger and Explorer maps of the Ordnance Survey.
Mr. Barnard told the Telegraph: "We have made several hundred now in England and Wales, but we have only reclassified about 30. The operating system data is very good."
