Cragfast is a Lake District term used to describe a sheep or other animal that has become stuck on a crag or cliff and cannot get back to safety. If not rescued the animal will usually die from exposure or hunger. In Winter Holiday Chapter 11, Dick Callum edges along a narrow ledge to one of Mr Dixon's sheep which is trapped. He ties it to a rope and the others lower it down from the ledge. The explorers take it back to Dixon's where it is revived.
