View west over part of the 500 acre Cleveland Potash complex near Boulby, north east Yorkshire, in October 2009. The deepest mine in Britain by far at 4,600 feet (and second deepest in Europe), construction began here in 1969 and production of potash, a key ingredient in agricultural fertilizer, commenced in 1973. A secondary product from the Boulby mine is rock salt, which is also produced in high volumes. The site generates large amounts of rail freight traffic, handled via a link to Teesside along the route of the former Whitby, Redcar and Middlesbrough Union Railway, closed in 1958 but reopened from a junction west of Saltburn when production commenced here in 1973. Because of its depth, the site is also home to the UKs Zeplin-III dark matter detector, which is housed in the Boulby Underground Laboratory. Now wash your hands please. See image 33493
