It should also be mentioned that the circumstances mentioned above might coincide and overlap. Since direct belays rely on fundamentally sound anchors, they may not be an option in some of these extreme scenarios. Belayers may need to insert their own bodies into the system, using stance to supplement the anchor, relying on the anchor as a backup only. Moreover, there is such a thing as a no-win scenario in climbing and in anchoring, when the available resources, the working skill set, or various dire circumstances will not allow an appropriate anchor to be built. When faced with this scenario, a tactical retreat, a call for assistance, or the aid of another climber is preferable to settling for anchors that may well result in catastrophic failure.

THE TRIPLE S: FUNDAMENTALS OF COMPLEX ANCHORS

When anchoring becomes more complicated, a more sophisticated approach positions the anchor builder to answer three basic questions:

Is the anchor strong enough?

Is the anchor secure enough?

Is the anchor as simple as it can be?

This is a broader, more inclusive way to think about anchors than the SERENE-style mnemonic. Call it the Triple S approach. Triple S anchors do not strive to equalize or to eliminate extensions; they strive to distribute load intelligently, minimize extensions, and avoid edge-case failure scenarios. Triple S anchors do not attempt to aggregate strength; they rely on unquestionably strong component parts and anticipate a human factor in that calculation. Triple S anchors do not muddle into unnecessary complexity; they solve the anchoring problem as efficiently as possible.

Strength. An anchor must be adequately strong to sustain all potential loads ap- plied to it. Then, an anchor’s strength must be padded with a margin of error that could account for any number of mistakes that all humans are wont to make. Let’s be conservative and provide ourselves with a 100 percent margin of error. That would mean that any anchor should be strong enough to sustain all potential loads applied to it multiplied by two.

Security. This means that if anything unexpected happens—components fail, the direction of load changes—the anchor must survive those unexpected changes. An anchor that is secure has backups. It has systemic redundancy all the way to the masterpoint. If any single point in the anchor were to fail, other points would pro- vide adequate backups. We make a few exceptions for anchors that are so titanic in nature (large, stable trees and boulders) that we might rely upon these single features alone, but even these features could be rigged in a redundant fashion.

Simplicity. A climber needs to appreciate that any anchor can quickly become convoluted and overly complex if it is rigged to solve phantom hazards or improb- able contingencies, or if it slavishly adheres to anchoring principles that are unachievable. For any given anchor, simplicity refers to the overall amount of time to construct and deconstruct an anchor. Simplicity refers to the overall amount of equipment needed, including rope, slings, carabiners, and any amount of pad- ding or edge protection. All this should be minimized. Simplicity also refers to the number of knots being tied and untied, the number of steps needed to construct the anchor, and the distance the components are separated. All these should be minimized too.

When time, equipment, and number of steps are all minimized, and an anchor still demonstrates adequate strength and security, an anchor will have achieved the best end result our current knowledge and technology can offer.
