Wensley Quarry is an active limestone quarry near to Preston-under-Scar, North Yorkshire, England. Products from the quarry include industrial carbonate, crushed rock aggregate, and agricultural lime. The quarry used to send out regular trainloads of sinter dust to the steelworks on Teesside until 1992, when the railway loading point closed.
Wensley quarry did not start producing limestone until 1947, however, the adjacent quarry (Redmire Quarry) was sending out industrial lime as sinter dust to the ironworks on Teesside since 1912. When Redmire closed in 1992, Wensley Quarry increased its output of industrial carbonate,[1] though it had been producing this commodity for British Steel in the 1970s and 1980s anyway.[2] All of Wensley Quarry's current output goes by lorry along what is known locally as the Tank Road, but that from Redmire was taken by an aerial ropeway to the loading sidings at railway station to be moved to Teesside via Wensleydale Railway until the loading point closed in 1992.[3]
Wensley Quarry covers, and is 1km (01miles) north of the village of Preston-under-Scar. The quarry lies outside the Yorkshire Dales National Park, with the park boundaries being about to the west, north, and south.[4] The quarry is at an altitude of above sea level and works a carboniferous limestone of the Alston Formation, producing rock for aggregate, industrial carbonate, and agricultural lime.[5]
Whilst many limestone workings have historically been active in the area, Wensley Quarry was not developed until the 20th century, with planning permission granted in 1947. The permission covers an area of and had no time limit, something which prompted the residents of nearby Preston-under-Scar to clarify through an appeals process.[6] [7] A decision from the House of Lords means that a section of the quarry is free from being developed as part of the workings. Currently, the owners (Tarmac) have permission to work the quarry face until 2042. English Nature and the local parish councils have raised concerns about the quarry as it borders the Lovely Seat SSSI to the north.[8]
The quarry produces around of limestone per year.
