Before you consider something like this, you might want to look into Carlsbad
Caverns findings on their various shafts like the elevator shaft. I know 3"
doesn't sound like much, but it will change the dynamics of the cave. Maybe
this situation simply means 20 plus cavers shouldn't be in this bad-air passage
at the same time.
