Wire rift, mud hall, boulder chamber, upper traverse, rabbit warren, plantation, gour hall, sump 1. Back out via stal pitch, cerberus series, everest, boulder chamber, fracture rift, coral chamber, rocky boulder, mud hall, wire rift.
Had planned to go to sump 2, but the water levels on the approach passage to sump 1 were very high, only a few inches of airspace (which I didn't fancy on my own). I think the dam just before sump 1 must have been left in. So I turned around and came out via Coral chamber.
