4. Setting Up Climbing Anchors

Selecting Anchor Points

The foundation of a secure climbing anchor system lies in the careful selection of anchor points. This choice is crucial whether you’re using natural or artificial anchors.

Natural Anchors

  • Assessment: For natural anchors like rocks or trees, the first step is to assess their stability. Is the rock solid without any cracks or signs of weakness? Is the tree alive, well-rooted, and thick enough?
  • Load-bearing Capacity: The anchor must be capable of supporting not just your weight, but also the additional forces generated during a fall.
  • Environmental Considerations: When using trees, it’s important to minimize damage. Using wide slings or tree protectors can help preserve the bark and health of the tree.

Artificial Anchors

  • Integrity Checks: For bolts or other fixed gear, ensure they are not loose or showing signs of wear. Rust, movement, or cracks around the bolt are red flags.
  • Correct Installation: Make sure that any gear you place, like cams or nuts, is correctly seated and secure. A good practice is to give them a gentle tug to test their stability.

Equalizing Anchors

Equalization is a technique used to distribute the load evenly across multiple anchor points, minimizing the risk on any single point.

Methods and Gear

  • Slings and Cord: I typically use slings or cordelette to create an equalized anchor. The material should be strong and in good condition.
  • Knots: Mastering knots like the overhand or figure-eight on a bight is essential. These knots are used to tie the slings or cord into a secure system.
  • Angle of Forces: The angle between each sling or cord should ideally be no more than 60 degrees. Wider angles increase the force on each anchor point, potentially leading to failure.


  • Backup Systems: Always have a backup in your anchor system. If one point fails, others should be in place to bear the load.
  • Regular Checks: Once set up, I always double-check each component of the anchor system before proceeding.

5. Safety Tips for Climbing Anchors

Safety Tips for Climbing Anchors

Ensuring safety while climbing is not just about using the right gear; it’s also about knowing how to use that gear correctly and consistently following best practices.
