Slaughter Stream Cave
Slaughter Stream Cave, also known as Wet Sink, is a cave system in the Wye Valley, Forest of Dean. A series of fixed ladders and two pitches lead to sporting streamways, sandy crawls and fossil passages. The cave also contains some interesting archaeological finds, many historic bones were found in the cave – the most prominent of which is 'Norman', a dog who was trapped in the cave many years ago and whose footprints and skeleton can be seen in Dog's Graveyard passage. An episode of the Channel 4 documentary Extreme Archaeology was filmed in this cave. It is the longest cave system in the Forest of Dean followed by Miss Grace's Lane.
