How do Mountain Climbing Anchors Work?

Mountain climbing anchors are essential tools that provide climbers with a secure connection to the rock or ice they are climbing on. They allow climbers to rest, belay, and rappel safely.

There are two main types of mountain climbing anchors: passive and active. Passive anchors, such as nuts, cams, and hexes, rely on friction to hold them in place. Active anchors, such as bolts and pitons, are mechanically connected to the rock.

The choice of which type of anchor to use depends on the terrain, the type of climbing being done, and the climber's experience.

Passive anchors are typically made of aluminum or steel and are designed to fit into cracks or other irregularities in the rock. When a climber places a passive anchor, they twist or hammer it into the crack until it is secure. The anchor then holds by friction between its surface and the rock.

Active anchors are typically made of steel or titanium and are connected to the rock by a bolt or other mechanical device. When a climber places an active anchor, they drill a hole in the rock, insert the anchor, and then tighten it until it is secure.

When choosing a mountain climbing anchor, it is important to consider the following factors:

  • The type of terrain you will be climbing
  • The weight of the climbers and equipment
  • The potential for the anchor to be exposed to falling ice or rock
  • The durability of the anchor
