161 - Surveying upstream in Lost World

Sun 27 Jul 1997
Sam Lieberman

Discovered a section of _large_ passage containing many mud formations and showing evidence of backing up. Very sump-like. Much of passage (named Bournville Lakes?) was ~5m wide, highly linear and v. tall, hading slightly. Dived off down, even more sump-like, entering a tube before leading ultimately to a small mud-choked bit. The water had cut deep trenches in mud banks but seemed to seep into choss in the floor. Surveyed this lot so didn't have time to complete the whole upstream survey.
