Overview
- Ten cavers entered Mossdale Caverns on 24 June 1967, four turned back, and six were trapped by sudden storm-driven flooding.
- Morag Forbes returned to find the entrance submerged and ran more than two miles across the moor to raise the alarm.
- More than 300 people joined a rescue led by the Upper Wharfedale Fell Rescue Association with the Cave Rescue Organisation, but rising water blocked entry until the next day despite trenching Mossdale Beck.
- Five bodies were recovered first; the sixth, John Ogden, was found later in a rift after a search led by Brian Boardman.
- The coroner initially advised leaving the bodies in place, the families later arranged reburial in the mud caverns, and the closed site now carries a Grade 5 rating with a plaque and cairn commemorating the dead.
