Plug and feather debris clear from the rift below Echo, followed by hoisting spoil up to the 166' level. The holes drilled last week at the narrowest part of this rift were filled and fired at the end of the session.

Also, following the North Pot team commenting that fumes from our activities are evident in their side of the cave, we tested for a sound connection. We already know that drill noise is audible, but considered this would travel well through rock so a whistle was used. Nick went to 'Over the Hill' in North Pot, and blew a whistle and a set time, which was faintly audible to Hollie at the South Pot dig face. 

Nick describes Over the Hill as having a too tight aven entering part way along, and suggest this is possibly where our dig may end up. 

This gives us something to think about, though it looks like we've got several weeks of spoil clearing to do first anyway.

Before leaving we loaded up the surface skip with some of  North Pot's mud, and hauled that to surface to help out.
