Four walkers have been saved after an eleven-hour night-time rescue operation in gales and rain on a 3,000ft Snowdonia peak.
A dozen mountain rescuers and a coastguard helicopter were involved in the search.
The walkers had set off at midday on Saturday hoping to climb North Gully on Tryfan. However, they decided to change their plan as the weather deteriorated.
The group crossed steep and dangerous ground before becoming stuck in the area of Grooved Arete.
Ogwen Valley mountain rescue team were alerted and used a smartphone app to help locate the group. But it was impossible to make voice contact due to the high winds and the group only had two small torches to try to attract attention.
They were finally found tucked into a crevice more than 200ft below the eastern traverse and ropes were used to rescue them.
