Three men were brought to safety following a cave rescue lasting more than 30 hours in "appalling conditions" during Storm Amy.
The experienced cavers were stranded in the challenging Dowber Gill Passage, near Grassington, North Yorkshire.
The alarm was raised at 22:00 BST on Thursday when they failed to return and one of their wives called the police.
Upper Wharfedale Fell Rescue Association said more than 100 volunteers took part in the "long and difficult" rescue, which was hampered by worsening weather, flooding, rough terrain and long hours underground.
By the time the men were found in the early hours of Friday, rising water levels meant the simplest way out was impassable, forcing the rescuers and the cavers to retrace their steps.
