Three men have been rescued from a cave after being trapped for 30 hours by Storm Amy.
The experienced cavers were stranded in the Dowber Gill Passage, near Grassington, North Yorkshire.
On Thursday, police were called at 10pm by the wife of a man after he failed to return home.
More than 100 volunteers took part in the "long and difficult" rescue, according to Upper Wharfedale Fell Rescue Association.
The conditions made the operation through rough terrain challenging, with Storm Amy bringing increasing flooding in the area.
The search team found the men in the early hours of Friday.
Rising water levels meant the most straightforward way out could not be accessed, forcing the rescuers and the cavers to retrace their steps.
Rescue team leader Derek Hammond spoke on the "exceedingly dangerous" rising water levels.

He told the BBC: "Unfortunately, the weather had a different plan for us," he said.
"The immediate danger is the water and, potentially in certain parts of the cave, drowning.
"Had the water level risen in those places, it would have been exceedingly dangerous."
Neighbouring caving teams were called for assistance, including Calder Valley Search & Rescue Team, Clapham-based Cave Rescue Organisation, Derbyshire Cave Rescue Organisation, Royal Air Force Mountain Rescue Service and Swaledale Mountain Rescue Team.

The first missing caver was brought to safety on Friday afternoon, the second at 02.30am on Saturday and the third two hours later.
No injuries were reported.
The rescuers used relays to guide the cavers, while those on the surface maintained communication and managed logistics.
Traverse lines were installed to help people avoid having to wade through water.

Mr Hammond said: "It takes a strong man to survive that."
"Without that phone call from the wife, nobody would have known these guys were overdue until somebody saw the cars parked outside the cave for a couple of days."
He described the decision to undertake the expedition ahead of the stormy weather, as forecasts predicted the storm would arrive on Friday afternoon.
However, heavy rain arrived earlier and more intensely than expected.
