Entering the cave, visitors become aware of a faint sound that gets louder as they walk further in. Suddenly they turn a corner and find the first waterfall, which after wet weather literally thunders into a rocky pool. The waterfall was the first feature discovered by Christopher Long in 1923. In full spate the weight of water cascading down each minute is about fifty-five tonnes.
1923 - The Discovery of the Waterfall
In August 1923 Cambridge student Christopher Long was on holiday in the dales. He noticed a slight fissure in the ground, and decided to investigate. Spurred on by the distant roar of water, he struggled over jagged rocks and through pools, until eventually he found himself at the foot of a waterfall. On subsequent expeditions, Long swam across the subterranean lakes and squeezed past a massive boulder, only to find his path blocked by a jumbled mass of rocks.
