Hi just got back from a dry Wk/end in S.Wales
Today we entered a reasonably wet Little Neath River Cave once though the Entrance Duck their is a Terrible Smell of Oil or Diesel.
Once into the Larger Chambers the Stink was Gaging !
Through the Canal & Canal Bypass everywhere is covered in an Oily residue.
Their are Boulders oily & extremely Slippery up out the Water I know it's been wet lately so this might be recent ?
When we exited we Stunk of Diesel were covered in Oil.

Anyone been there recently ? 

I was there on Sunday too. Gaging is as well as stomach wrenching. Wouldn't recommend the use of a carbide lamp in there at the moment.  :yucky:

A misconception about diesel. Diesel vapour does not flash like petrol. You can even stick a naked flame to it and I don't think it will take fire. Mind you, I'm not going to experiment to see if its true or not!

you are indeed right Peter (though if its poured onto a 'host' substance such as a wick, it will burn).
its all to do with vapours and 'explosive mixtures' innit.

different story for petrol though..

Please let the Cambrian Caving Council Conservation Officer know if you haven't already. I don't think she reads this forum and I'm sure it'd be useful if the first hand accounts of the problem got to her. There is an e-mail address here:
