The little English hill, Miller Moss also known as Little Lingy Hill is celebrated today, after a pair of hill-measuring enthusiasts found it to be one metre higher than the Ordnance Survey calculated – sneaking it over the classification boundary that divides mere hills from mountains.
That threshold is 609.6 metres (2000ft). Hence mountaineers John Barnard and Graham Jackson have spent a lot of time hunting for hills that lie around the 609m mark and giving them a re-measure, bagging quite a few reclassifications as they go.
The problem with the Ordnance Survey’s data is that many of its height measurements are calculated from a 3D map generated from flying a plane over the land, with Barnard and Jackson instead manually going up hills and doing a reading with a high-end bit of GPS kit.
Hence Miller Moss having its official height changed from 609m to 610.1m and getting itself declared a mountain. The ranking of this newly founded mountain is not yet established but experts predict Miller Moss could be the shortest mountain in the United Kingdom.
Maybe don’t add a trip to the top to your 2019 stay-cation plans, though, as Barnard describes the summit as a “nondescript bump.” [Telegraph]
