Duckmanton Railway Cutting SSSI (2)

Another view of the Duckmanton Railway Cutting Site of Special Scientific Interest, near Chesterfield, Derbyshire.

The arch structure on the right is a shelter built to preserve and allow access to the the Chavery Coal and its overlying roof mudstones.

The railway cutting is a site of international geological importance, as it contains the stratotype section for the Anthracoceras vanderbeckei (Clay Cross) marine band which is the boundary between the Langsettian and Duckmantian Stages of the Carboniferous, informally the junction between the Lower and Middle Coal Measures.

The site is managed by the Derbyshire Wildlife Trust and is accessible by permit only.
