Which anchor method helps distribute load and provide redundancy on irregular surfaces?

• A. Single-point anchor.
• B. Broad, redundant anchor method such as a double anchor with slings and carabiners.
• C. A fixed knot around a tree.
• D. A temporary anchor using a single sling.

Answer: (B)

Distributing the load across multiple points while keeping a backup path is the key idea here. On irregular surfaces, a single contact point can shift, slip, or fail because the load isn’t shared evenly and the surface isn’t uniform. A broad, redundant anchor method uses several anchor points connected with slings and carabiners to form a wider, more stable anchor. This setup spreads the force across multiple points, so no one point bears the entire load, and if one point starts to fail or loosens, the others continue to hold. It can also be adjusted to keep the load path favorable and provides true redundancy by having multiple connection options rather than relying on a single sling or knot. In contrast, single-point anchors or knots around a tree concentrate force in one place and lack the redundancy needed on irregular surfaces, making them more prone to failure under load.
