Agreed, hence my quotation marks around the word dry above. Some caves genuinely stay dry because of their structure or location, and others can suddenly, lethally flood. but even the truly dry ones can kill in no time just like that through a litany of terrible reasons, experts and amateurs both being victims.

It would however be a bad idea for someone to assume a truly dry cave is thus safe enough to let their guard down because they know how much more dangerous flood-prone or submerged caves are.
