136 - 136
Returned to finish survey of day before, and look at new leads. Completed survey - most promising lead (trending SE) ends at infilled passage - may be possible to pass with short climb. Otherwise continues along small, narrow, wet 'Darrenesque' crawl. Also investigated passage going in opposite direction (Goo junction) - turns into short, narrow VERY muddy passage, into a squeeze leading to a sump and a very water-filled passage. Not recommended!
