Spoon:exactly but from what i read the rouses take it to another level
Yeah, but you should read about scheck exley and bill stone. This guys are the real pioneers in cave explorations. Here's a short article on Bill Stone

If I am not mistaken Bill Stone was the rival of the WKPP team of JJ when they both took a bid for the project to map Wakula Springs. There is supposedly some strong rivalry between the 2 groups.
Scheck on the other hand wrote the book on Cave Diving. During the early years of Cave Diving the fatality rate was so high that Scheck took time out to sit down and write a book on the basics of the sport. After the book was published, the fatality rate went down by more than half. The man has passed away in a cave diving accident but he is a legend in the cave diving community.
