Been a while since I've been in Harvey's what was the VIS like?

Anyway, I'm sure the sink lines have changed but the line starts tied to a log and then goes down, at about 70 ft it has a horizontal line that Ts into it. The horizontal line goes to the cave entrance, the other line simple continues to go down (not sure max depth) to the bottom of the sink, no other entrance. There are two deep areas in Harvey but both accessed from the cave itself.

Sounds like a line was added to go directly into the cave, in addition to the old one. Think it might have been there on my last dive, can not remember.
