Excavation by D Graham of SyAS prior to the installation of new wrought iron gates. The cave has been largely formed by the action of a stream, which still flows strongly through the cave. Evidence for 18th and 19th century management of the stream and cave was found, in the form of salt-glazed pipes, a brick lined drain, and a brick floor. No earlier features were observed, although no attempt was made to break through the brick floor to examine deeper deposits. (360)
