Avalanche

Avalanches are rapid, destructive flows of snow and ice that tear down mountainsides with tremendous force. Understanding how they form, what triggers them, and how to recognize danger zones matters for anyone spending time in snowy terrain—backcountry skiers, snowmobilers, hikers, and mountain communities. The physics behind avalanche formation involves slope angle, snow layering, temperature changes, and weather patterns that combine in ways that aren't always obvious from ground level.

These guides explain what causes different types of avalanches, how to read terrain and snow conditions for risk assessment, what safety gear and practices reduce exposure, and how to respond if caught in one. You'll learn why certain slopes slide while others don't, how to recognize unstable snow layers, and what rescue procedures work in the critical minutes after an avalanche occurs.
