Absolutely. And when it has been determined that a particular mountain has a large buildup of snow, then the conditions are declared unsafe... and they don't allow skiers on that mountain, because they might
trigger the avalanche.
Just because the trigger is small, or a common occurrence on all the other mountains that don't have a buildup of snow, doesn't mean the avalanche is inevitable. We can still prevent it in most cases.
