The cave was discovered in 1824/5 when miners digging a tunnel in the nearby Stalactite Cave, broke into the Bone Chamber to find that it was completly choked with cave earth and countless Late Pleistcene animal bones. It’s thought that the cave roof was open for thousands of years and the animals just fell in.
William Beard excavated here until about 1840 but no new explorations were done until the Axbridge Caving Group started again in the 1950s and extended the cave to its present length.
