Powder Snow Vibration Sensitivity on Mountains

I've seen quite a few suggestions for either giving powder snow gravity, make it move like a liquid, make it harder for players to get out of it with debuffs, or to implement full on avalanches. So I'd like to add my own idea to the pile.

If powder snow does get gravity / liquid movement, I think it would fit well for the powder snow to start moving when disturbed by vibrations. This could realistically trigger avalanche-like events by causing powder snow on the mountainside to flow down, sweeping up anything in its wake if players aren't careful enough.

It'd also be neat if using the archeology brush on natural powder snow (or a kind of "packed snow" block) had the rare chance to drop items and mob drops found in the area as if they had been buried in past avalanches.
