Rescuers were called out to search for two walkers who had gone to investigate a cave that was recently featured on television.
The father and son decided to spend the night in the Priest’s Hole on Dove Crag in the Lake District.
The cave recently featured on BBC One’s Secret Britain when presenter Chris Hollins made the ascent to the site.
A Patterdale MRT spokesperson said: “When the pair didn’t return the following morning and could not be contacted on their mobile phones, Cumbria police requested Patterdale Mountain Rescue Team start a search for them.
“The team started to check the main routes that lead down from Dove Crag and requested the assistance of the Lake District Mountain Rescue Search Dogs. As one group of team members made their way on to the hill a pair matching the description was seen walking down.
“It was quickly established this was the missing pair and the team was stood down.”
