"The dive guide headed toward the low point in the rear of the cavern, and right above the floor there was a hole in the back wall, about three feet in diameter, that led to ... well, I have no clue what it led to"
So, if someone had had a first stage failure, or an OOA, how would they have gotten out? Were they trained to exit single file & had the requisite equipment? And this was at the back of the cavern with OW divers?
I've never dove anywhere besides the cold, dark and often low vis waters of the PNW, but I'm pretty sure I can't breath the water even where it's clear and 'friendly looking'.
This seems like such a no brainer to me personally, I don't understand why this requires discussion. IMO the divers had no reason to go there. DM or no DM.
Just my $0.02
