snow compaction

Snow compaction refers to the process where snow becomes denser and more tightly packed over time or through external pressure. When snow falls, it’s initially light and airy, but as additional snow accumulates, or when weight from foot traffic, vehicles, or natural factors like wind press down on it, its individual snowflakes are compressed closer together. This increase in density affects the snow’s firmness, stability, and thermal properties. Snow compaction is important for activities like skiing, avalanche prediction, and understanding how snow insulates the ground or gains strength over time.
