I was browsing Tik Tok (yes I am ashamed) and saw a video of caver in pretty narrow passage. So that caver took another rock and started to chip in order to widen a little bit the passage, while complaining about not having a hammer with him.
I am a climber, not a caver, and that kind of behaviour would be a big nope in the climbing world (There is a few exceptions where it was done (usually after involving the federation and local community), and it's still pretty controversial)
So I am curious about caver opinion on that practice.
The saying among the caving community is that cavers go in to save spelunkers. The only people who really call it spelunking are people who don't go caving very often.
Yes, generally seen as a last resort to provide access past a squeeze but I know of several caves that have had Kilometers of passageway added to their surveys through the enlargement of a single point.
I have heard that it is inadvisable for solo or inexperienced spelunkers because you could easily dislodge something that could crush you, collapse a cave, etc.
Generally NO, the only acceptable defacement of caves I've seen are bolts to accommodate rappelling down shafts. Of course with commercial caves they have to do quite a bit of defacement.
Not always. I run a commercial tour (approx 5k visitors per annum, so fairly small in the great scheme of things) - one of the things we pride ourselves on is keeping the cave in its largely unmodified state. It's really special to be able to share that with people.
Not a caver, but I’ve watched a few spelunking vids online. The attitude of most - at least on camera - seems to be that you respect the cave and tackle it as-is rather than trying to modify it.
