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.
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.
