Or how about a Thought Experiment? - imagine that we live in a country populated with a fair number of active cavers, who engage in working out the route for themselves, based on their own experiences, into caves which have few sources of description and no surveys. Right, fix that in your mind.
How long do you think it would take before some bright spark said "Hey, I've got an idea! - why don't we draw up maps of the caves we visit so that (a) we know where we've been (b) we know how long the cave is (c) we can work out its relationship to the surface and this might provide clues about likely places to dig (d) the map would be really useful to other people wishing to visit the cave and (e) it would serve as a reference for people who seek, find, and add on, new bits of passage as the cave is explored and pushed further and.... (f) we might even sell a handful of copies".
You never know, if enough people thought it was a good idea it might catch on.
