'The Stork', one of the most famous stalactites at Treak Cliff Cavern
Treak Cliff Cavern is a show cave near Castleton in Derbyshire. It is part of the Castleton Site of Special Scientific Interest and by agreement with English Nature all the Blue John stone deposits on the visitor route are preserved. However, Blue John is regularly mined from areas not seen by visitors. This is then crafted into jewellery, small bowls, ornaments and other decorative items.
