Eldon Hill

Eldon Hill is a hill in the Peak District National Park in the county of Derbyshire, England, 4 kilometres (2.5 mi) southwest of the village of Castleton. It is a 470-metre (1,540 ft) limestone hill whose pastureland is used for rough grazing, although a large proportion has been lost to limestone quarrying. It lies within the Castleton Site of Special Scientific Interest. Eldon Hill was formed when a bed of pure limestone was squeezed and upfolded by geological forces to form a dome; it is the highest limestone hill north of the River Wye. The hill is of considerable geological, historical and industrial interest; it lies at the northern limit of the carboniferous limestone in the Peak District, as further north it merges into the millstone grit of the Dark Peak. The name Elveden is first attested in 1285 as Elvedon and seems to have meant 'Elves' hill'. Quarrying permission was granted in 1950 and huge quantities of limestone have been excavated, mostly for road-building purposes. A large amount of the northern and northwestern slopes of the hill have disappeared and it has been called the best-known eyesore in the Peak District. In 1995 an application by RMC Aggregates to extend the quarrying further east was denied as parliament tightened up on environmental problems caused by old mineral permissions granted between 1948 and 1981. The quarry closed in 1999 and now stands unused with vegetation starting to grow on the quarry face. There have been some attempts at natural restoration with several aquatic pools being established in the former workings. The termination of quarrying has also given cavers the chance to explore some of the narrow caves exposed by the work, with Sidetrack Cave (discovered 2002) being one of the most impressive. In September 2020 the quarry was used as a film location for a TV series called Ray James, inspired by H. G. Wells' The War of the Worlds. 350 metres south of the summit lies Eldon Hole. At 55 metres it is the deepest pothole in…
