Snow anchors: how strong are they?

Описание к видео Snow anchors: how strong are they?

The ENSA equipment testing department studied the strength of different types of snow anchor commonly used by mountain climbers, skiers and rescue workers: snow-stakes, ice-axes, skis, ski poles…etc.
These are known as deadman anchors.
The results suggest that the angle at which a deadman is placed, significantly affects its holding power.
