Objective Check visibility and flow upstream past the Black Abyss.
Logistics Single Stage, Single Scooter
Bottom Time 52 min.
Maximum Depth 192
Results Rode in through the Black Abyss to the restriction. Flow was way down. Water level also way down (by 2′ for this time of year). The water is not tannic but it is almost stagnant looking. It got bluer at 170′ but is not yet adequate for exploration. This means that southern Leon Sinks is definitely not explorable by now. Scootered around the Black Abyss and then did the decompression by riding over to Emerald. Corrected Line Arrows that were facing the wrong direction and removed Hero Clips from the upstream. Did oxygen in the trough to fill it back up.
