@Jumpyman--I believe he was saying that just as canary being affected by
poisonous gases in a coal mine being a warning to miners, this small avalanche
that didn't kill anyone is a warning to back-country skiers that larger,
killer avalanches are looming. Seems perfectly apt to me.
What does a little bird in a mine have to do with an avalanche? I am trying to
see the connection. I suppose that the guy quote was referring to the use of
canary to detect poisonous levels of gas in coal mines, but I how does a small
avalanche relate to that?
