Team called by Cumbria Police after concerns for a walker who had become benighted on a section of the Kentmere Horseshoe. With limited information available, due to network coverage, they also called Langdale & Ambleside MRT as both the teams border run along the summit. With both teams deployed, Kendal searchdog Fern, with Handler Dave, found the walker close to the Yoke and was able to escort them down safely to one of our vehicles.
