Learn about glacier hazards. As part of your initial learning on climbing a glacier, be sure to learn glacier rescue techniques. Some important things to understand about glacier hazards include:
- Glaciers have crevasses (i.e., large cracks) and falling down one often means death. Learning to avoid crevasses is the first step; learning to arrest yourself or to help another person when fallen down a crevasse is the next crucial step.
- Crevasses are often very difficult to spot because they are hidden under snow.
- Snowbridges form across glaciers. Sometimes these can be crossed by humans; other times they will break under the weight. The strength of such snowbridges is weather dependent.
