Team contacted by Cumbria Police, cries of help had been heard by walkers on Yoke, part of the Kentmere horseshoe. A gentleman and his son had become cragfast on Star Crag. We sent in one team from the reservoir to ascend and another team via the Garburn pass to descend. Fortunately it was a relatively easy rescue and soon both the lad and his father were on the summit. We drove them down and back to their car in Kentmere.
