NY8468 : Former Tramway to Frederick Shaft
taken 10 years ago, 3 km from Newbrough, Northumberland, England

Former Tramway to Frederick Shaft
This was the main shaft for the mine. It is 700ft (213m) deep. The shaft was driven through boulder clay (laid down in the last Ice Age) and whetstone before reaching the whinn sill where the lead and witherite ore bodies were to be found.
