Mentioning the snow in a thread is enough.
And since the avalanche comes from the surface, it counts as well!
Somebody also mentioned being snowed in: You aren't trapped in Kalinor all season! The Woven Gate cannot be used in the beginning of the season, but the snow will eventually be removed. Besides there are other ways out of Kalinor (they cannot be used by humans though).
So you can also accomplish the goal of eating a hot meal on the surface!
