Team McKinlay, Armantrout
Objective Check downstream Emerald: main tunnel to Clearcut and parallel tunnel to Fish for leads and tannic water source
Logistics Double stage w/ towed backup Gavin
Bottom Time 60
Maximum Depth 195
Results Fish tunnel visibility was 20-30ft and hazy. Lines were everywhere and in very poor condition. Decided time would be better spent in the primary tunnel heading to Clearcut Sink. Travelled past where the arrows turned and the tunnel became shallow (140ft) before dropping back to 160ft. Nothing in the way of leads. Estimate penetration at 4,000 ft. Dive conducted entirely on stage bottles.
