Avalanche Formation

Snowpack formation

The snowpack consists of layers formed by:

  • Variations in temperature, wind, humidity, etc. during storm events.

  • Sun, wind, humidity, temperature, rain, etc. acting on the surface layers of the snow and changing them from their original form.

  • Metamorphism of the sub-surface layers due to internal snowpack conditions (such as temperature, pressure, etc.).

Factors that drive change in the layers of the snowpack are always present; therefore the layers are constantly changing. This change can be rapid (e.g. freeze-thaw of the surface layers) or slow (e.g. long-term metamorphism of the sub-surface layers).
