Breaking ice curtains on lead: what would happen in the worst possible scenario?
|
As a novice ice climber with the ice season underway, this scenario has occurred to me a number of times. I'm curious what you might think would happen: |

"One of his most painful experiences happened in his hometown of June Lake on Jan. 29, 1996. He and two friends, Pete Schoerner and Doug Nidever, had decided to attempt a first ascent of a new ice formation that had formed up on a wall just a half mile from their homes. At the last minute, he had to opt out due to some work-related issues. But he watched them from his job site from down below, and then tragedy happened... “I watched Pete take a 130-foot fall when the ice detached from the wall,” Rosnau said. “He died. The following morning, Doug, myself and another friend went up to recover his body, 400 feet up the wall. It remains one of the most painful experiences of my life.” Read more here: tri-cityherald.com/news/loc… |

If the chunk of ice your screw is in falls for any reason it will most likely rip you off and kill you and probably your partner as well. Be careful what you attach yourself to. |

It's not rare. You'll want to continually asses the quality of the ice you are climbing on. My only lead fall on ice was when a large block came off, and both my tools were in that block. Fortunately my last screw was in solid ice. |

That said I have been on many climbs that were pillars, the vast majority of the time they are done as a solo. I have also been on curtains that have cracked and or shifted, sometimes while on them. Here again they are often done as a solo. |

for a real life example of this phenomenon, look for the account of it happening to Canadian Ice legend Barry Blanchard back in the mid-nineties. As I recall, Blanchard was climbing with his wife. He had commenced an unsupported curtain, placed a screw, climbed above to where the ice was adhered to the rock behind it - when the curtain below, with his screw, cut loose. This was before leashless ice tools, so Blanchard was attached to his tools with wrist leashes. His tools placements held, and he did not fall, but the weigh ot the ice in which his screw was placed loaded his leashes heavily enough to dislocate a shoulder. they aborted the climb... knowing the internet, I'm sure the write-up is around somewhere... |

Yet another reason why I likely won't ever ice climb... |

The way I think of a curtain or pillar snapping with you on it is as if the lead climber weighs several tons. A cubic meter of ice (a block 1m x 1m x 1m) weighs almost 1 metric tonne - a curtain or pillar could be several tonnes. The belayer's weight becomes trivial. He/she gets sucked up to the first screw, if pro and rope don't pull or break. Both climber and belayer likely get pounded by tons of breaking ice. In the case of someone like John in the video above having the sense not to place any pro in a pillar, I as a belayer would not even attach myself to the rope. I would wait until the climber is off the pillar and has placed trustworthy pro before threading the belay device and attaching it to myself. Overall, a bad idea. Avoid it... Or make sure a deus ex machina appears at the last minute and throws you a toprope: http://blogs.denverpost.com/sports/2012/07/10/viral-video-ouray-ice-climber-rescued-seconds-big-fall/22111/ I did this once in Yosemite on a rock climb. Pretty effective. Don't count on it though ;) |

Worst scenario? The falling ice starts an avalanche wiping out the power lines below causing a state wide blackout. The cooling system at the nearby nuclear power station fails and the reactor explodes, a satellite sees a nuclear strike and Trump orders a retaliatory strike against Russia, North Korea, Iran, Pakistan and China. They respond and the world becomes a radioactive Armaggedon. |

The good news is that as a novice ice climber you will be staying away from these horror shows. Stay on slabby easier routes. Dial in your technique. Follow a lot. Lead when you are proficient after loads of practice. AND no one will make you climb a hanging curtain like that. If sonething looks unsafe, climb elsewhere. |

I hope we were smart enough not to put nuclear power plants in slide paths. I think the avalanche would have.to be epic enough to block a river (removing coolant source) or some butterfly effect type thing. |

And in case the off-site power source fails, the nuclear power plants have massive diesel generators to power vital equipment, including cooling systems.And then. there is the gravity-fed Refueling Water Storage Tank, then... |

Climb carefully, waiting until above the attachment point before placing a screw. Your tool placements and movement skills are your belay until then. |

I think the question ultimately comes down to how strong the ice is that screw 2 is placed in. Drop tests have shown a very wide range of ice screw strength, ranging from a few kN to 20+kN. If you have a totally bomber placement for screw #2, it's unlikely to come out as the ice tumbles down. Even if it's just a few kN, that's more than enough to take you with it for quite a while, likely all the way to the ground, depending on the terrain it hits as it falls. I really can't imagine this scenario playing out very well. |

Thank you all for the great responses. |

I believe this video is close to what your talking about. |
