These videos are arranged in the order in which the skills of crevasse rescue normally flow. All videos are produced by the American Mountain Guides Association (AMGA) and provide an excellent reference for one flow through a rescue system.
Made with a picket, both horizontal (t-trench) and vertically placed. The style of anchor you use often depends on the density of the snowpack.
Lots of ways to manage this process, this video presents an effective method.
How to get from self arrest to having an anchor support your fallen climber.
The first piece you placed, while holding a fall in self arrest, might not be that reliable. This is a great method to add a second anchor point. You can consider burying an axe, or other tool if you don't have two pickets.
Here you'll see a technique to prepare the edge of the crevasse so that your rope does not get stuck when you add mechanical advantage
Sometimes, you may have to go down into the crevasse yourself to help your fallen climber. If they need first aid, or got knocked unconscious by their fall, you'll need to get down to them to help.
This is the most complex rope system in the crevasse rescue skillset.
Finally! Combining a 2:1 system with a 3:1 system to get your fallen climber back out of the crevasse.
Combined, these skills should help you review what we've learned, and stay ready to go.
