Top Rope Anchor
|
Hey guys! Just looking for suggestions on how to build an anchor off two boulders with a static rope? |
|
That's fine. |
|
Thank you! Sorry but what do you mean by clip the rope back to itself? |
|
Just how big are these boulders? Do you really need 2? I'd probably just wrap it with a cordellette and tie a figure 8 on a bight. Redundant where it needs to be and much faster. |

1 Tie a bowline on 1 boulder |

Tie a figure 8 on a bight. Use a carabiner (locking or O&O) to attach the figure 8 to the rope that goes back to your masterpoint. |

James, please ignore the advice to use just one boulder. Always go for redundancy unless that is not possible. Your life is worth the extra time. |

Yes, ignore the advice to build an appropriately solid anchor in the off chance that a massive seismic event manages to send a truck-sized Boulder off the cliff yet somehow miraculously doesn't pull you down with it. Redundancy is important, but not for its own sake. A second massive, unmovable Boulder or tree doesn't make you any safer. With big natural anchors, the only real need for redundancy is in the soft goods which can be cut on sharp edges. A knot accomplishes this. |

The issue with only slinging 1 boulder is that it has to be directly in line with the climb otherwise the static line will swing across the edge which could potentially cut it. An additional anchor point will prevent this from happening. Other than that, a single boulder is fine, provided it's big and stable. |
|
OMG. Where to start! |
|
Thanks everyone for the advice! |
|
Again, ignore the advice from the obviously thin-skinned poster who will put convenience over safety. |

YGD!?!? I looked all over (for about 40 sec). What the hell does that mean? |

What the hell does that mean?My guess is this classic: m.youtube.com/watch?v=39fyT… One or two boulders depending on size and proximity to the climb. If u have enough rope and it makes you feel better - and it lines up better - sling em both. Boulder is a relative term. To some it means a rock they can't pick up, which isn't always big enough. If you could climb a route on it, clearly it isn't going anywhere. On the upper end, Boulder is a city. Edit: As stated above, have an experienced anchor builder check your work until you have no further questions about the subject. |

Lol. I'd say a boulder the size of Boulder would be ok as 1 of 5 legs on an anchor, as long as they are dynamically equalized by 2 quads. |
|
Back to the OP, did u mean two fig-8 on a bight for the master point? Trying to figure out how u would do a follow through on that efficiently. |

I second picking up "Climbing Anchors." For instance, in it Long reminds us that not all boulders are good boulders. He cites the SAR method that boulders should be at least the size of fridge, but more importantly, well situated in the wall (not likely to move). Well worth the read. Be safe! |
