Loose snow avalanches occur when a layer of loose, dry snow slides down a slope. This type of avalanche typically starts from a small area, often triggered by a person or natural factors like warming temperatures. As the snow begins to slide, it can gather more snow and increase in size, moving quickly down the mountain. These avalanches are most common on steep slopes, especially those with fresh snowfall. They can be dangerous for skiers and snowboarders, as they can sweep away anyone in their path. Understanding the conditions that lead to loose snow avalanches is crucial for safety in mountainous areas, particularly during winter months.
