...determines when snow conditions make avalanches more likely. Snowpacks of differing strength are built up over time and the interfaces between them can be lubricated by finer powder snow. Avalanches can be deadly, but sadly far more people are killed by mudslides and landslides. The processes involved are similar, with layers of rock or soil being lubricated by water. In...
