A couple attempted to climb the highest mountain in southern Britain without an Ordnance Survey map - and found themselves lost in the dark.
Central Brecon Mountain Rescue was called out after the pair from Somerset found themselves lost in the dark on Pen-y-Fan, having set off at lunchtime without a map, compass or torch, Grough reports.
The rescuers responded to their call by getting them to download the OS Converter smartphone app, which used GPS
to pinpoint the position of the lost walkers and enable team members to find them and walk them down to safety.
Deputy leader of Central Brecons Mountain Rescue Mark Jones commented: "Technology saved us all a night on the mountain, but it can never take the place of a traditional map and compass and being properly prepared."
The need to be prepared is important at any time of the year, but right now is a key period for having a map and torch, with yesterday (December 22nd) having been the shortest day of the year.
