Scary Gear Pulling Lead Fall Video
|
|
Thanks for the reminder Ron. There is not easy statement or fast solution here. As noted, always nice to have more than one piece between you and the ground. Maybe increase that to multiples if you think you will be falling or the rock is slick and the climber is relying on cams. Some cams have better holding power than others (cam angle, cam material factor in). I trust Metolius and Totems more than Black Diamond for that reason. (still use BD's as well though) Judging placements can be problematical as well. |

I've fallen on gear many times on quartzite at Devils Lake, on small cams. There is also a thread about cams on slick rock: Cams at DL |

I'm pretty sure that if the rock surfaces were perfectly parallel and the rock were frictionless, the placement would fail. Some rock is pretty slick, and some cracks are pretty parallel-sided, soo... Yep. Sounds so much like religion that I just can't even... Makes me think of another weekend activity they might like. |

Also the first cam was actually a BD .3, not a .4. |

|
This video is also a great reminder to periodically check your camera and make sure the lens is clean .... |

Right on, Vincent. |

Whats with the big wall rack?? I have climbed with partners who have climbed for years and notice they place cams perpendicular to the crack instead of in line with potential fall. These are guys with years of trad experience and it blew my mind they made such a rookie mistake. Could your buddy have placed the cams perpendicular? |

The placements that failed could both be easily seen from the ground. Both cams were directly in line with the cracks in which they were placed. No significant rotation could have occurred. |
|
|
How do we explain the cam that actually held? This was placed in the same type of rock. And actually had tons of force placed on it. |
|
|
Too much gear being carried. The climber simply weighed too much |

Well, Josh does raise a fair point, pulling multiple pieces of that size is pretty unusual. But it's good to stay open to possible limitations of the gear, and I (and I guess rgold as well) have seen cams (smaller than these) that looked totally fine and then pulled with a VERY light tug out of a Gunks horizontal. Since that experience I always look for a crystal or ripple or other constriction to put physics on my side a little more, so that I'm not just relying on friction. |

Just trying to help educate others re: the risks. Note: It was somewhat warm and humid. Although it had rained heavily the night before, the rock was completely dry. Ron, thanks for posting this. I appreciate the spirit in which it was posted. Cams can and do pull (obviously), hence the general rule to place them a body length apart at places like Indian Creek. But I'm wondering, if you weren't leading and didn't place the gear, how do you know the above to be true? I look at the video, and (at least from what you can see) the guy appears to be trashing around a bit, which can prompt sloppy placements. Like most others on this thread have already said, the most obvious reason is probably pilot error. |

True Fat Dad, the pilot error is the simplest and most likely explanation in the vast majority of cases. In this case, the gear was placed from decent enough stances. The 'thrashing' didn't ensue until the climber attempted to pull the roof. Was the placement of a cam altered by the thrashing? It is certainly possible. |

What are those weird claw-like pieces of metal in that photo, down the crack by his feet? |

Given that the rock was obviously slick, he should have extended using something better than a draw. Even when rope drag is not an issue, a quickdraw is going to impart a lot more force from rope movement to the cam, thus increasing the probability of it walking into a bad placement. Something like a single length sling or even an alpine would have been a much safer bet. |

Maybe go back there and test the cam placements a bit. With a solid tr backup(!), place them with a tug/without a tug/various positions and extension configurations, bounce test them, take some simulated (tr backed up) lead falls on them. If they pulled do to lack of friction, I'd think you'd be able to replicate the "failure". Be safe out there! |

Seems like it should mimic a perfectly smooth parallel crack pretty well: A lot of vices have a knurled, grooved, or grained surface to hold the work piece, so maybe not. |
