Inside there are a couple of places with a welly-depth of water so rubber footwhere recommended. There is also a misty section between two of the air shafts where photography is nye on impossible as everything comes out blurred. The eastern portal is breeze blocked up. There is a hatchway 20 feet off the ground with a new signal gantry style ladder up to a platform on the inside and nothing on the outside so the maintenenace crew can get in with a ladder. Of course, the local youth has provided a knotted climbing rope so access is possible at both ends.
More stalactites. And what the heck is that radio-active sign thingy? Anyone know? I assume it is nothing more sinister than the surveyor's personal way of marking the tunnel? This is a good, 'textbook' tunnel! Get it while it's cold!
