> He realised the water at the surface of the lake was drinkable Can someone explain this phenomena? How can the water in a sea-cave become potable?

Fresh water is less dense than salt water, so perhaps fresh water seeped through rocks from above and didn't mix with the sea water.

Cave diving is one of those things that I am happy to only experience vicariously through the stories of others.

Or you can watch Youtube vids like this : https://www.youtube.com/watch?v=WtlwoX1YEmg This has got to be the scariest video on Youtube in which no harm comes to anyone.

Not claustrophobic safe.

When you're learning to cave dive, one of the first things that you learn is that you may very well die in there. Most of the training focuses on systems, skills repetition, and understanding and using redundant systems - folks getting into cave diving typically are already extremely experienced divers who if anything need only some minor skill tweaks - most cave instructors will not take on students who don't alread…

I'd also like to add "The Last Dive" by Bernie Chowdury - https://www.amazon.com/Last-Dive-Father-Descent-Oceans/dp/00...

I'm quite surprised at the detail that the rescuers attempted to drill into the cave from above in order to provide supplies .. is anyone familiar with the depth of the cave pocket? This seems like a surprising choice to make given the logistics - but I guess a safer one, in the end .. assuming one has a drill system available and the depth is not too great.

There should be a law against bringing in and leaving nylon ropes in the cave. If this continues, all the caves are going to be filled with nylons ropes left by previous divers. Do we want these caves, too, to eventually become a garbage dumping ground?

Wouldn't littering cover it?

Off topic, but here is a viable contender: https://www.youtube.com/watch?v=hFMHjDqHL_Y

There are videos of higher towers, but I believe that this video is the most thoroughly annotated one.
