The pair, a man and woman in their late teens, had set out walking from a local campsite and were unable to find their way back.
The walkers were located using SARLOC, a protocol which interrogates smartphones for their position. A small party of volunteers was then deployed to find the walkers and assess them for injury. The pair were cold but otherwise unharmed and were brought safely back to the site by around 1:30 a.m.
