IIRC, spelunkers of old were not allowed to blow their way through millions of years of history just to set records, apparently times have changed. I'll bet if this were happening in the US, the Sierra Club would be throwing out restraining orders like crazy, making cops go down into the cave and bring the offenders out, lol.

When I was a little Airman, I used to do some spelunking. Unless you're caving on private property, the restrictions now are Orwellian.
