True or False? The Most Enduring Myths About Snow and Ice

Avalanches Are Triggered Only by Loud Noises: Sound vs. Science

The dramatic depiction of avalanches triggered by loud noises in movies has perpetuated a myth that sound alone can cause these deadly snow slides. In truth, avalanches are primarily triggered by weight, such as a skier or new snow, disturbing an unstable snowpack. While sound waves can theoretically trigger an avalanche, the conditions required are rare and unlikely. Avalanches result from complex interactions between snow layers, weather conditions, and terrain. Understanding these factors is crucial for avalanche safety, debunking the notion that noise is a primary cause and emphasizing the importance of proper risk assessment.
