Yesterday morning I took the first of four groups of cavers through the labyrinths of limestone under Bungonia.
We had a ball! Grill cave was wetter than usual, with lots of mud and big puddles down low. Unfortunately, this also meant the CO2 levels were also higher than usual. I took them down deep enough to experience some mild effects of CO2, showed them what a lighter does in it's presence then back to the surface.
The second cave, Hogans hole and fossil cave, was much more fun, very dry and after we went through the cement bag, the five cavers had fun comparing who was the dirtiest.
Lunch on the lookouts overlooking the beautiful Bungonia Gorge, then back to Canberra for a welcome shower and a good night's sleep!
It's a funny old P.C world we live in isn't it? I come from the country where we all called them black-boys. I've heard the rings of the trunk grow an inch per year.
Very interesting Baz, but you wouldn't get me doing that for all the Tea in China, I will be down there soon enough for good without going down there for fun
Thanks guys. I went again yesterday and met the SAME BLOKE underground, half way through a cave, that I met last year and guided through the cave. (He was just down from Sydney last year and asked to tack on to our group). Half way through Hogan's hole/Fossil cave, there he was, looking at me saying, 'Don't I know you?" What's the chances of that?
No way in hell I would be climbing around those caves, to tight for me.
The Grass tree is also known as "Black-boy" or "Fire Spear", on average they grow 1cm a year. The trunk is made up from the dead, dry grass as it dies off.

and the perfume from the sap is exquisite! Especially in the fireplace.
Thanks for the picks Barry. I also woulodnt / couldnt go down through such small openings.
I am curoius to learn what the effects of C02 are.
And also what a lighter does in C02 as I couldnt make it out from the photos.
If you couold let me know I would be grateful.
G'day Geoff, the Co2 makes the lighter flame appear a few inches above the lighter, with a large gap in between the lighter and the flame.
Co2 can turn you into a pink puffer, a blue bloater and give you headaches, dizziness, loss of energy, shortness of breath, rapid heartbeat, unconsciousness, convulsions and death. It all depends on the duration and concentration as it saturates your blood.
