Ha ha ha, the best part of this discussion is that while we waited for
9 hours for the divers, we burned just about every scented candle that
Mallory had purchased at a Bath and Body Works blowout sale! Not only
did we have stale air from nasty smelling wet suits and heavily
breathing sherpas, it was intermingled with the enticing aromas of
"Butterfly Garden" and "Sweet Pea." In addition to adding heat to our
trash sacks to keep us warm, the candles also did an OK job of letting
us know that there really wasn't that much CO2 in the passage.
Mallory packed up most of the candle stubs before we left; on the way
out of the cave, every time we'd come to a low spot in the ceiling, I
could smell those frickin' candles again. I suppose that those scents
will always remind me of this particular tank haul trip.

If you have 20 something cavers in a small passage with bad air

I propose future trips take precautionary measures and release some
oxygen
into the passage.
It would be little use to install a big fan and flexible conduit to
force some air into the shaft entrance
because the air would distribute evenly throughout the whole cave and
it would also block the entrance
from easy in and out trips.
Also,
A tiny air shaft could be drilled, that could also be used to lower
the diving gear into the room where
the divers suit up at.
Even a 3 inch diameter shaft would be helpful, because you could lower
a telephone cable, or pump
oxygen into the room, lower emergency food and water, etc.
I propose a 3 inch shaft be drilled to confirm the exact location of
the 1st sump, and then use the
diver's survey to mark the surface where the cave is going.
I would also like to propose that the TSA, TCMA, and every Texas caver
unite behind a single goal, and
I believe that goal should be to finish the map of Honeycreek. (
after ICS of course )
I hope I live long enough to see the TCMA acquire the Shaft Entrance
and at least some sort of permanent
access agreement to the Natural Entrance, like an easement.
