Shortly before 9:00 p.m. Team call-handlers were made aware of a lost walker on Hen Gerrig between Lake Vyrnwy and Llandymawddy. The male in his 20’s had started out from Lake Vyrnwy in the morning with the intention of walking a planned route. During the day he became disorientated, and strayed well away from any notable footpaths or his intended route. Having recognised his predicament, the male called Dyfed Powys Police for assistance. W ith failing light and no water or torch, the walker had become anxious and concerned for his own safety. Call-handlers used smart-phone technology to locate the man and attempted to direct him down off the hill, but a combination of factors made it difficult for the walker to follow instructions and directions. Team volunteers deployed to the area and made their way as far as possible up into the forestry in a team vehicle before continuing on foot to the casualty’s location. The man was medically assessed and provided food and water before being escorted back down to the team vehicle. The male was transported back to the main road and met by family members for transportation home. All team members were off the hill by 2:30 a.m. Saturday.
