Did a 2500' double stage dive yesterday at Hole in the Wall in the Downstream Tunnel. Vis was beautiful with just a small/negligible amount of particulate in the water for about the first 1600'. After that got a little milky with a decent amount of particulate in the water in spots, and after about 2300' the vis went to about 50' or less with a good amount of stuff in the water.

There are a lot of fin marks in the clay bottom, which is sad, but it is still the most beautiful cave I have been to thus far. I would definitely recommend having your buoyancy perfect before venturing into this system, since there are a lot of drop-unders between domes and the bottom is silt and clay. Also, the water is REALLY COLD (I'm as wuss), 66 F and some parts have a legitimate thermocline if you drop to the bottom of the cave.
