The two walkers, a man and woman in their 20's and from the Birmingham area, had set out from Minffordd earlier in the day, but had become disorientated in poor visibility on the upper ridges of the mountain and had unintentionally descended on the north side rather than the south side of the range. Their passage through increasingly broken ground had started to aggravate an existing injury in the mans knee, and when darkness fell they sensibly decided to seek assistance from Mountain Rescue.
Call-handlers were able to deploy the SARLOC application which is able to quiz the casualties smartphones for its GPS location, and got an exact position for the couple. A small party of ASART volunteers was then able to make their way directly to casualties' location. The pair were escorted down off the mountain to Gwernan Lake, a slow process given the tussock and gorse-covered nature of the hillside, and everyone was off the hill by 11:00 p.m.
