John Cooper, Kate Lawrence, Wayne Starsmore, Adrian Vanderplank and Jude Vanderplank. Clearance session today. All the rocks at the bottom of Father Duckmas shaft were moved up in stages, initially to the top of Father Duckmas, then to the Tunnel, then to the bottom of the entrance shaft and finally 13 rather heavier loads reached the surface. Still fairly dry and warm, 14°C on the surface, and not too drippy underground. 2½ hours. John.
