The couple, in their early 50's, were uninjured but had become disorientated on the plateau of Foel Dinas. A good phone signal meant that a discussion could be had about their journey so far, and any landmarks they could see. The use of the SARLOC protocol to quiz their phone for its location gave the final confirmation of their location.
With this information, the call-handler was able to give verbal instructions to direct the pair to a suitable exit point from the plateau. In the meantime, two more volunteers set off walking up to meet them.
Everyone was safely down off the hill by 6:15 p.m.
