An excellent trip. We headed through Rocky horror which is a massive passage with huge boulders covering the floor to Trident series to have a look around. We have it on good authority that no one has been in this part of the cave since the 80s and there was an old supply dump from then, the entrance we had found making a much quicker way in. Trident was richly decorated which lead onto large passage. There's lots of question marks in this part of the cave, ready to explore in the summer. We surveyed a small inlet for about 90m.
