I’ve spoken with the cave divers at Wakulla Springs, in Florida. They’ve done a bit of serious research there, mapping it back several miles. The opening of the cave is 120 feet below the surface, and goes deeper still (I’m remembering 300 feet) once one gets inside, with the pressure of the water pushing outward. They compress for 6 hours, can be down there for 6 hours, and then decompress for 6 hours on the longer expeditions. AFAIK no one has died in that one, at least not for a very long time. There are mastodon bones at 90-120 feet, that one used to be able to see from the surface.
