Caplecleugh Firestone Level Nenthead, Cumbria, OS Ref: NY78654229.
The Caplecleugh Firestone Level follows the Caplecleugh North Vein and it was driven below the Firestone Sill. A line of shafts north of Old Carr's Burn marks the vein and the early workings. The level was presumably driven for drainage of the shaft workings. No further history of the level can currently be found.
If you do visit for a look please leave the entrance as you found it, as it has no gate. Normally the level is flooded, for our visit we had to pump it out to get in.
