Shortly before 4:30 p.m., Team call-handlers were informed of concerns raised over an out-of-contact walker.

The woman was walking a 9-day long distance route moving north through the Eryri National Park. Her last known position was camping near the summit of Cader Idris on Sunday evening: some 40 hours previous, and she had failed to make contact from that point onwards.

Given the elapsed time, the potential search area was significant, and it was unclear whether she was indeed in any trouble at all. Enquiries were made with the national park ranger service with regard to abandoned tents in the area, but nothing conclusive was forthcoming.

The following day, one of the rangers reported the sighting of a lone female, well north of our area, who seemed to fit the description of the "missing" woman.

With a degree of evidence that the walker was no longer in our area, and she was potentially doing no more than having switched her phone off, or having a flat battery, the Team was stood down.

Shortly before 4:30 p.m. the Team was requested by the Welsh Ambulance Service to assist in attending a man reporting chest pains near the foot of Cader Idris.

​As it turned out, the ambulance crew was able to reach the casualty, near the Tea Rooms at Minffordd, and the Team was stood down.

​Shortly after 3:00 p.m. Team call-handlers were made aware of a walker suffering from heat related illness near the summit of Cader Idris.

The woman, part of an organised group, was showing symptoms of heat-exhaustion/heat-stroke, a potentially life-threatening condition. At least two members of the group remained to help the casualty, but the others, including the organisers, opted to continue with their day, and played no further part in her care or rescue.

The group members who remained on scene with the casualty were assisted by a number of members of public including a GP. They were able to provide an important flow of information to co-odinators as the rescue developed.

As Team volunteers made their way up the mountain, the woman's condition had improved greatly in the cool of the summit hut, and she was assisted slowly down the mountain to meet up with the approaching rescuers. Everyone was safely off the mountain by 6:00 p.m.
