Interesting read and story;
An elite diver died after getting trapped while navigating an underwater labyrinth that the diving community refers to as some of “the most dangerous caves” in the world. Shane Thompson, 43, a deep sea diver and Navy vet from San Diego, Calif., was exploring the treacherous cavern underneath the Blue Hole, a popular swimming hole known for its crystal-clear waters near Santa Rosa, N.M. Thompson was part of a two-person excursion with the ADM Exploration Foundation, who got rare access to the mysterious caverns, which have been sealed from the public since they claimed the lives of two Oklahoma student divers in 1976. The excursion Thompson was participating in was the latest part of a two-year effort to map out the maze-like caves and make them more accessible. Thompson lost sight of his diving partner and got disoriented inside the narrow cavern passageways and became entombed overnight. The expert diver was on an excursion with fellow diver Mike Young, when “everything went terribly wrong,” Santa Rosa police officer Mika Gauna told the San Diego Tribune. The two divers entered a narrow chamber about 194 feet deep in waters with no visibility due to the silt. “Shane was supposed to stay out and for whatever reason entered the cave,” Gauna said.

overhead enclosure diving is incredibly dangerous. At 194 ft as well? Fuck that.
RIP |

Seems like a UUV might be a better choice to map out dangerous caves.

Sounds like a serious navigation error. There was no permanent line where they were at so all they had to exit on was some braided #24 line. The lack of flow probably didn't help him much either. So when the silt out occurred he went to the line, my guess is that he pulled out the placements as a result of disorientation and could get back out.

I've done enough confined space diving to realize all those tricks they tell you in a classroom (like watching which way your bubbles rise) can get overridden very quickly by panic. As with all things, I would anticipate numerous failures will be cited (particularly losing or not having his line out). Running out of air in a confined space in the dark by yourself has to be an incredibly bad way to go.... |

194 ft? Wonder if Nitrogen Narcosis got to him. Either way fuck that shit.
I say that as a certified public safety diver who has done plenty of blackwater dives. |

Nope.
Wrecks creep me out. I won't go anywhere near a cave. RIP |

Safety line. Safety line, Safety line. Never leave home without, or you may not leave the cave.
Poor bastard, I cant image the hopelessness that guy felt. I suppose, as some tiny bit of comfort, I hope his lights help out longer than his oxygen. |

That method of checking out gives a person way too much time to contemplate their demise.

Interesting to read that Young NOW wants the caves sealed off for being too dangerous even though HE got permission after they had been off limits. While tragic, that is total BS and my respect for him dropped like a rock.
Also sounds like both divers failed to regroup after things started to go wrong which is absolutely a no no. |

By the time Young finally found Thompson, he was already dead. View Quote Not sure how your partner has air, finds him, and dude is already dead. |

I used to live in a town not too far away from Santa Rosa. Knew people that dived that hole, but didn't know it was that dangerous.
Lord, what a terrible feeling that must have been. |

Nitrox I bet Without having full details, I'd suspect that a caver granted special access would be on a depth-appropriate bottom gas with travel gas staged at proper points if not just rigged alongside. I'm just a low-time NAUI open water guy certified in '91. Of course, the Navy air tables do go down to 190', and the Rouses opted to go deep air for their fatal U-869 dive. |

From the article secondary link to:
http://www.scubaboard.com/community/threads/shane-thompson.524794/page-2 Shane searched and recovered my husband, Jeff's, body in 175 feet when the city of LaJolla ran out of funds. Shane is our hero & we are devastated by the news of his passing. It is a truly sad event and our family is forever grateful for Shane's ability to share his skill set with others because "you can."

I've been through Santa Rosa, total shithole. Nothing against the diver.
|
|
Just no, no, no, will not go into something like that.
A prayer for him and his family. |

Famous last words from the experts:
"It will never happen to me, because I'm an expert!" Sorry the the family's loss though. |

I've been on numerous dives (around 50, I know this is nothing compared to most)
I have done enough diving to be dangerous. Open water stuff is great but I had considered something more. The subject of cave diving came up and it is very interesting to me. I asked my instructor (long time friend/professional fireman) This man is a great diver and I would feel comfortable doing almost any dive if he were with me. He advised me against cave diving. The fact that he wasn't comfortable doing them, told me that I have no business in underwater caves. I will be limited to admiring them from safe distance |

Running out of air in a confined space in the dark by yourself has to be an incredibly bad way to go.... True that. I remember my first night dive I got separated from my partner and had my torch go out. Thought to myself, no big deal, I'll just slowly ascend, I was only around 30ish feet, no biggie. Couldn't see my bubbles, water was in no way clear and there was no moon. I ended up swimming horizontally for 12 minutes before I realized my plan was not working. Throw yourself in a cave with zero vis? Noooooope. |

By the time Young finally found Thompson, he was already dead. Not sure how your partner has air, finds him, and dude is already dead. He was panicking and breathing faster, using up his air faster. Or, since he was supposed to stay outside the cave went down with less air since he wasn't going to be exerting himself. Either way, as soon as the silt went up cutting off visibility, they both should have left. And they should have had communication gear. |

This isn't some dumb ass who brought his kid with him or deserves a Darwin award or was committing a crime. It's a 43 year old explorer with a family. That guilt that you must have somewhere deep down at piling on and posting something you can't possibly think is funny... I'd listen to it. |

Caves are not a no, they are a HELL NO.
I feel bad for the family, glad they at least recovered the body quickly. |

He didn't follow the plan, according to what I am reading. Going in after saying he was going to stay out.

Been posted here before, but an interesting read about another experienced cave diver.
http://www.outsideonline.com/1922711/raising-dead Ten minutes into his dive, Dave Shaw started to look for the bottom. Utter blackness pressed in on him from all sides, and he directed his high-intensity light downward, hoping for a flash of rock or mud. Shaw, a 50-year-old Aussie, was in an alien world, more than 800 feet below the surface pool that marks the entrance to Bushman's Hole, a remote sinkhole in the Northern Cape province of South Africa and the third-deepest freshwater cave known to man.
