Britain's largest cave rediscovered

The BBC records another triumph for the East Midlands:

A cave believed to be the biggest in Britain has been unearthed in the Peak District in Derbyshire.

Titan is thought to be almost 460ft (140m) deep, as high as the London Eye, sculpted out of limestone by rain water over millions of years.

Local potholer and underground explorer Dave Nixon led the team that discovered it, near Castleton.

He began searching for it after reading an account by an obscure 18th century academic in a university library.
