Two 14-year-old girls were rescued on Wednesday following a land-and-air search after getting lost on a mountain near their homes.
The Ogwen Mountain Rescue team deployed 20 people in the search
The search involved 20 members of the Ogwen Valley Mountain Rescue team, two helicopters and rescue dogs.
The two, from Dwygyflchi and Llanfairfechan, near Bangor, had set off on Tuesday morning.
The alarm was raised after the pair contacted a parent to say the batteries in their mobile and torch were failing.
According to Alastair Read from the Ogwen Valley Rescue team, a combination of events resulted in the girls needing help.
He said: "They had walked from Dwygyfylchi to Rowen but on the way back they missed the path.
"They then contacted a parent to say their mobile phone battery was getting low and that their torch battery had failed and they could not see their compass and map."
Thermal-imaging equipment used by the police helicopter had trouble picking up the girls because of the location.
Mr Reade said: "There are a lot of sheep in the area and the camera could not find them. The fact that they were wearing camouflage clothing also made them difficult to spot against the vegetation."
The girls were eventually found safe and well at 0130 BST on Wednesday.
