The Longest Cave tells the story of many years worth of exploration as cavers tried to connect the Flint Ridge and Mammoth Cave systems.
The parts where they are out beyond the Candlelight River just felt so remote. Same where they were trying to knock rocks out of a breakdown pile at station Q87. It was hours and hours of travelling to even get there, then the work started. Then you had to get back out!
Another thing that I found interesting, as a new caver in 2009, was the gear they used back then. We have fancy lights and helmets, protective suits, special packs, GPS above ground, com systems below ground, and so on. The carbide lamps and overalls don't sound quite as nice as the gear we have today.
The moment where they made the big breakthrough / connection was really well written. I felt like I could understand the odd psychological "flip" and mental disorientation that would come from knowing that its over 12 hours to get back out the way you came, to all of the sudden seeing a tourist rail in front of you.
Must have been a very exciting time to be a caver.
