An embarrassed walker on a Snowdonia peak had to be rescued after getting lost then realising he only had a map of part of Scotland with him.

His problems were compounded when he then damaged the mobile phone he was using for its mapping.

The man, in his 40s, had gone on his own on to the Glyderau range on a clear evening with a bright moon to recce an upcoming mountain challenge.

But a blanket of cloud descended on Glyder Fach and Glyder Fawr.

Chris Lloyd, of the Ogwen Valley Mountain Rescue Organisation, which was called out shortly after midnight on Thursday to help the man, said: “Knowing that the area can be treacherous if the correct routes are not followed, he reached for his map in his rucksack.

“Sadly, this was the map he had used the previous week in Scotland.

“Fortunately, he had mapping on his mobile phone so was able to continue.

“But unfortunately, he damaged the screen on the telephone making any further map reading impossible.

“He made the 999 call reporting that he was lost in dense cloud cover on Glyder Fach summit.”

The team got a fix on his position using the Sarloc system developed by former Ogwen Valley MRO member Russ Hoare which relies on sending a hyperlink to the person’s smartphone.

My Lloyd said: “Two team members were dispatched.

“They found the embarrassed gentleman on the summit as reported. He was escorted to safety.

“This was an unfortunate incident but avoidable had he checked that he had the correct map.”

• Yesterday, the team was called out to help a 15-year-old boy who was knocked unconscious after falling down a crag and into a ravine.

The boy was with his parents and younger sister on a high-level walk above Aber Falls when he fell 7m (23ft).

His father ran to get help and the team was called out.

Mr Lloyd said: “This is an area of a communications nightmare, so he raced down the hillside to find a telephone.

“With the report of the incident, 22 Squadron [from RAF Valley] was immediately requested.

“Meanwhile, four team members made their way to the site.

“The boy was winched up by the Sea King, his father having jumped on board whilst the helicopter was on the ground 200m away from the incident.

“Mother and daughter were escorted down to their car and then escorted to Ysbyty Gwynedd hospital in Bangor.

“It is hoped that this is just a case of severe concussion.”
