Hey, Robert.
I'm no expert, but, I will post your message to CaveTex, where folks much more intelligent, experienced, and educated than I can, hopefully, help. OK, y'all, time to dazzle Robert with your collective brilliance! Thanks and good luck on your story!

I'm co-writing a sci-fi adventure story, and would like to ask for help on several questions (that I can think of now, anyway) concerning tunnels and caverns. My characters are now in one of a series of caverns and will be traveling through them for up to 25 miles. The caverns are both natural and man-made, deliberately designed and connected for underground transportation. Two of the group of four have calcium carbide lamps fixed to their helmets. 1. In a long tunnel - c. 6’ wide x c. 8’ high; about a quarter of a mile in length - can a sensitive person detect changes in air pressure, humidity, and smells, the deeper in and down you travel in this tunnel? 2. Can you feel air moving in such a long tunnel that leads to an air shaft? 3. If you hover over an air shaft on the surface, can you feel/detect air movement going in or out? 4. If you are in a cave, tunnel, or cavern for up to three days, do you lose track of time? Could a person go to sleep for several hours and wake up, thinking it must be morning? 5. What significant developments can a person experience in long term caving? If you are not in a position to respond, can you direct me to someone who can? Thanks for any help.
