English: Black Hill (Holme Moss) Ordnance Survey Triangulation Pillar At 582 metres (1,908 feet) above sea-level, Black Hill (Holme Moss) was once "the highest hill in old Cheshire" before local government re-organisation in 1974. On the OS map, the locality is alternatively known as "Soldier’s Lump", this being a reference to the 18th century visits of the Royal Engineer surveyors who first used it as a surveying point. Nowadays the concrete Ordnance Survey triangulation pillar at Black Hill summit (Flush Bracket number 2958 - the absence of the ‘S’ prefix denotes that this is a primary pillar) languishes in the middle of an all-enveloping quagmire of wet, knee-deep goo. You can see how much the peat has eroded over the years as the base of the pillar, constructed in 1936, is now a few feet above ground level. Before the paving slabs were laid, after a period of heavy rain, the pillar used to be virtually unapproachable, but a very welcome sight in thick moorland clag.
