What is a sluff? |
A sluff is a layer of loose snow. On rare occasions, an avalanche may be comprised of sluff rolling down a hill, but more frequently it is a dry or wet slab that causes an avalanche.
Most avalanches are triggered simply by gravity acting on heavy snow banks, but sometimes a careless snowmobiler or skier may be the culprit.
