Crossrung

Crossrung is a term used in the context of climbing and mountaineering to describe a situation where a climber is caught between two fixed points, such as bolts or anchors, that are not aligned vertically. This can occur in various climbing disciplines, including sport climbing, trad climbing, and mountaineering. The term is derived from the fact that the climber is effectively "crossed" between two "rungs" or fixed points.

Crossrung situations can be challenging and potentially dangerous, as they can lead to a variety of problems, including:

1. Difficulty in moving: Climbers may find it difficult to move their body or limbs freely, which can hinder their ability to climb or descend.

2. Increased risk of injury: The awkward position can increase the risk of injury, particularly to the shoulders, elbows, and wrists.

3. Difficulty in using protection: In trad climbing, crossrung situations can make it difficult to place protection, which can increase the risk of a fall.

To avoid crossrung situations, climbers should carefully assess the route and plan their movements accordingly. In some cases, it may be necessary to use specialized equipment, such as a crossrung sling or a crossrung belay device, to safely navigate the situation. If a climber becomes crossrung, they should take immediate action to resolve the situation, such as moving their body or using a device to free themselves. In extreme cases, a climber may need to be rescued by a partner or a rescue team.
