Self-arrest is the technique of stopping yourself after a slip or fall on a snow slope by using an ice axe to dig into the snow and halt your slide before you gather dangerous speed. It is one of the most important and practiced mountaineering safety skills, drilled repeatedly because a real arrest happens in seconds.
How it works
You roll onto the ice axe pick, weight it with your chest, and lift your feet — vital with crampons on, to avoid catching a point.
Why drill it
Snow slides accelerate fast, so arrest must be instinctive — essential for glacier travel and steep snow. Educational only; not a substitute for hands-on instruction.
Frequently asked questions
What is self-arrest?
Self-arrest is the technique of halting an uncontrolled slide down a snow slope by rolling onto the ice axe and driving its pick into the snow while keeping your weight over it. It's the key self-rescue skill for snow travel, used the instant a slip turns into a slide.
How do you self-arrest?
You grip the axe with one hand on the head and one on the shaft, roll toward the head onto your chest, press the pick into the snow with your shoulder and chest weight over it, lift your feet (especially with crampons on), and spread your legs for stability — all in a few seconds.
Can you self-arrest with crampons on?
Yes, but carefully — you must keep your crampon points off the snow during the arrest, because catching a point can flip you or break an ankle. This is why self-arrest with crampons is practiced specifically, lifting the feet rather than digging them in.
