Too cold to climb
|
I am heading to RR for New Years 1-3 jan. Weather projected to be in the 30-40s. Too cold to climb? |
|
I would say that is a personal choice. I have been on several climbing trips were we woke up every morning with frost all over the tent and temps in the high 20s. We just bundled up, found something in the sun, and had a good time. |
|
I don't know if that's true dylan b aluminiumdesign.net/why-alu… |
|
No offense but I think one anecdote of seeing a carabiner break when dropped doesn't provide sufficient evidence to contradict material sciences research. I guess you're never going to go ice climbing? |

Dylan B. wrote:Definitely too cold to climb. When temps get that low aluminum gets brittle and it increases the risk of microfractures in your caribiners.This is not true. It is of steel and some other metals, but aluminum does not get brittle as the temperature decreases. Dylan B. wrote:No, it's true. I once saw a brand new quickdraw dropped from the first bolt of a sport climb and both of the 'biners snapped in half when they hit the ground. It was only about 45º that day. The aluminum couldn't take the cold.Then why are ice axes made of aluminum? or ice screws? or ice tools? |

Low-Temperature Properties. Aluminum alloys represent a very important class of structural metals for subzero-temperature applications and are used for structural parts for operation at temperatures as low as -270oC. |
|
Just consider jet liners which are made of alluminum. I believe climbing gear is of the same type of alluminum. Aircraft are subjected to many cycles of cooling and warming around -50 degrees and the wings don't snap off. Surely someone will chime in to include numbers on this. |
|
I am in Jtree now. It won't be an option after tomorrow. Its very cold here and chasing sun is an option but the forecast here is also calling for snow NYE. Not sure anything in the region will be climbable after Tuesday:( |

Edit: nummy num nums! |

YOU ARE GOING TO BE HAVING OF THE DYING!! |

From a metallurgical article: |

This thread is pure gold. |

Dylan B. wrote:But I seen it with my own two eyes, I did. Shattered both the caribiners into a hundred parts. Who am I gonna trust? Some anonymous science website or my own two eyes? They probably believe humans come from monkeys when anyone with two eyes can see monkeys got tails and humans don't.no you're correct. thats why ironworkers dont work when it is this cold (in CO currently) because the steel structure of the buildings is too fragile (frah-gee-lay) to walk on |
|
In Norway we climb cold carabiners, cold cams, and it do no break, and all while having the cold nuts also! |
|
way to hijack this thread, Dylan. Refer to guideline #1. |

This is awesome. Ha ha. Thanks for the cold weather advice along with the long string of metal physics lesson. |
