Description
Area, 2.3 ha5.7 ac Description Pus Gill forms a deep, densely wooded ravine at the base of Dufton Pike. The stream running through Gus Gill and the village of Dufton forms part of the River Eden catchment and the stream sides are of geological importance as they represent the type section of the Pusgillian stage, the lowest stage of the Ashgill series of modern usage. The stream section contains the type section of the “Corona Beds” and has yielded type material of both brachiopods and trilobites. Rocks of Onnian and Lower Longvillian age are also represented in this fossiliferous section, the most extensive Pusgillian section in the north of England and thus a key National reference section.
