Snowpack Structure

Snowpack structure refers to how snow crystals are arranged within a layered system on the ground. It includes various levels formed by different snowfall events, each with distinct characteristics like density, temperature, and compactness. These layers influence stability and potential for avalanches. Fresh snow creates a new layer, which can be softer or lighter; over time, layers may harden or become unstable due to temperature changes and melting. Understanding snowpack structure helps assess avalanche risks and predict how snow may behave under stress, essential for safe activities in snowy environments.
