## Caves & Mines

- [Slaughter Stream Cave](https://gloucestercaving.co.uk/caves-and-mines/slaughter-stream-cave.md): At over 14km in length, it is longest UK cave formed in dolomite, and the 10th longest cave in the country. It has a wide variety of passages, unique formations, fossils, and the infamous 'Norman' skeleton (presumed to be remains of a dog), deep within the system. Until very recently, it had a single entrance known as Wet Sink, giving it the title of "Longest British cave with a single entrance". However, with the recent connection of Kiln Piece Hole, this is no longer the case.
- [Redhouse Lane Swallet](https://gloucestercaving.co.uk/caves-and-mines/redhouse-lane-swallet.md): The most recent, big find in the Forest of Dean, and even in the UK. Redhouse is now over 11km in length and continuously growing. Until recently only a tight and arduous streamway, the cave now boasts the biggest passages in the Forest of Dean as well as some of the most unique and well decorated. Redhouse has unlocked the gate to the previously unknown Symonds Yat Cave System.
- [Otter Hole](https://gloucestercaving.co.uk/caves-and-mines/otter-hole.md): An infamous, and unique cave that is controlled by the tides. The gloriously muddy entrance leads via a passage that floods every high-tide to reach some of the best decorated cave passages in the UK.
- [Windrush Stone Mine](https://gloucestercaving.co.uk/caves-and-mines/windrush-stone-mine.md): A charming little stone mine set in the village of Windrush in the Northern Cotswolds. This site has been reopened and explored by members of GSS with the history and artefacts being documented and written up in a recent publication.
