An evening stroll up to Hallowe’en Rift with Don McFarlane and Joyce Lundberg who are interested in carrying out some more stal dating on material from the cave. They weren’t dressed for an underground trip and seemed content to pick over the spoil heap for suitable material. I did venture down the shaft if only to get a hammer to break up some larger lumps of stal.
