: Welcome to Dartmoor, one of the richest and best mapped prehistoric landscapes in Britain. But not all of it has been investigated and there's a very good reason for that, because for the last 150 years this has been at the bottom of the reservoir that supplied the people of Torquay with their drinking water. Fast forward to the present day and the reservoir's looking pretty empty because the local water company has decided to pull the plug and give us a unique opportunity to explore a lost world. This could be some of the best prehistoric archaeology in Britain.
The only problem is now that we've got rid of the water, how are we going to cope with the mud? It really is, very difficult.
