Description

Area,1.6 hectares 3.9 ac Description This site covers a disused and partly backfilled chalk quarry where one face has been retained to show the chalk/soil interface. This reveals extensive piping in the top of the chalk resulting from solution at the Chalk Tertiary sediment interface. Believed to have formed during the Tertiary and Pleistocene, it is the finest exposure of clay filled pipes in the Chalk Karst of England.
