In 2008 & 2009 we did some work to the current entrance of Fairy Hole Cave
Several trips were made into the cave and we explored as far as the Coral Gallery
on the way out we noticed pyrite type formations in the streamway which could not be seen on the way in?
These were all generally above head height and the only thing I can describe them is like foam bubbles which have become coated in pyrite?
The deposit only appears on the upstream surfaces, which is why you can't see it on the way in it is very fragile (1 - 2mm thick)
Anyone seen this sort of thing before
